Among the many important fixtures on the welding table, you can find clamps for welding. They allow you to increase the speed of assembly of nodes and perform them in compliance with the main dimensions according to the drawing.
Industrial samples of clamps of various shapes are produced, but at home it is quite possible to make a reliable and convenient clamp for welding work on your own.
Clamps are produced not only for welding, they are used in carpentry. For locksmith work, similar devices are also produced. A convenient angle clamp for welding is an indispensable tool, without which sometimes you simply cannot do.
Clamps differ in shapes and sizes, they can be designed for a certain size of workpieces or used as a vice for welding with reliable fixation of parts.
There are also clamps designed for welding pipelines. These are designs on hinges and screws that allow clamping a pipe of a certain diameter.
Clamps can use a cam work clamp or a screw to help adjust the distance between the clamps. Several types and sizes of clamps should be present on the welding table, depending on the operations performed and the size of the parts. The simplest and most reliable homemade design welding clamp is a corner fixture, which is quite simple to make.
Structural features of the corner clamp
Angle clamps are designed to connect tubular blanks of various configurations at various angles. This can be an assembly of a frame structure for a gate, ready-made pipeline units or heating registers.
Depending on the angle of connection, clamps for welding can be with a constant joint degree, or with the possibility of setting different angles. Aspects that you need to pay attention to when developing a sketch and making drawings:
- for more reliable joining and fixing of parts, it is necessary to select a sufficient thickness of the clamping jaws. This will avoid large deformations during welding of the structure;
- pay attention to the clamping screws. The best option for a clamp will be nuts, and clamping parts made of copper or copper-plated steel with screw threads. Such a clamping device will last longer. In the absence of screw threads, metric threads can be used, but with the largest pitch;
- the size of the working surface when joining and welding parts. The best way- this is the possibility of welding from 3 sides of the assembly, which is in a clamped position.
The design of the clamp is a base with stops. The stops can be fixed at a certain angle or with the ability to adjust the degree of docking.
For fixing, a nut with a screw screwed into it is welded onto the base. This design allows you to fix workpieces of various sizes. Standard for normal conditions work accepted maximum size of 400 mm. For large sizes it will be necessary to apply the slipway.
Design variations
At the end of the screw, depending on the imagination of the master, you can make a steering wheel for clamping parts. But the simplest and most common clamp design is a small jumper welded or fixed in other ways from a square pipe or bar.
To fix small parts during welding, it is quite enough to make a simple clamp in the form English letter G. To do this, you can make the main frame with this configuration from the profile using undercuts and bends. A nut with a screw is welded on the upper part, and the simplest clamp is ready.
Despite its simplicity, it will securely fix small parts and help with welding. It is better to take a screw with a movable penny on one edge in order to securely fix the workpieces without moving them when tightening.
The most common is a clamp with the ability to adjust depending on the size of the workpiece. This fixture requires mounting it on a hard surface workbench for welding or on a metal craftsman's workbench.
F-shape
In order to facilitate the work, you will need to prepare a few simple clamps. In advance, you need to prepare small trimmings of any profile, a nut with a screw and fixing bolts. Angle clamps for welding are made in 2 stages.
Base
It will take three cuts profile pipe. You can use any profile that is at hand, but it is better to take it with different sizes shelves For example, a 25/60 pipe can serve as an excellent base blank.
Cut off parts with a length of 300, 200, 100 mm. Distribute a smaller segment in the middle of a long one and grab them. It turned out the base 180 mm in width.
From the larger edge, mark and cut corners at 450. A section of a profile about 150 mm long is welded in the middle of the long part of the base. A nut with a clamping screw will be attached to this part.
Cut off a corner or profile along the length of the bevel on the base and grab the pieces to the end of the base. These parts of the structure serve as guides for the blanks and as stops during fixation.
Boil all the joints and clean them well with a grinder with a cleaning stone. The base of the corner clamp for welding is ready, you can proceed to the final part of the assembly.
clamp
It remains to make a clamp. To do this, at the end of the straight cut extending from the base, a nut with a screwed screw is welded at a sufficient distance. To prevent damage to the thread during welding, the screw must be well lubricated with grease or other grease.
Now two parts of 100 mm are cut off, the ends are cut under 450, they are joined and the part is boiled. This will be the clamping bar. It can be made from a corner or a profile. You can bend it in a semicircle. In any case, it is important that it securely fixes parts of the structure.
At a short distance from the inner corner of the clamp, a steel plate 4-5 mm thick is welded. Then burn a hole for the passage of the end of the screw.
Clean the joints with a grinder. The end of the screw is inserted into the hole in the plate, and a retainer is welded to its edge. At the other end, a handle is welded for rotation.
The design of the clamp for welding in the corner version is ready. This is the simplest version of the clamp, which is easy to do with your own hands. You can make a fixture with several fixing screws or with a variable joining angle of the workpieces.
Making an angle vice for a welder is quite simple. Now it remains to attach the clamp rigidly using electric welding to a table or workbench. You can drill holes in the welding table and clamp the clamp for welding with a bolted connection.
The most common clamp will allow you to connect parts at right angles for tie-in or for assembling a wicket or gate.
In order to speed up and simplify the process of work, for example, when working with metal products, you will need a couple of angle clamps! In addition, after welding, the metal clamped into the clamp does not lead away as without it, and the angle remains 90 degrees.
It is not difficult to make an angle clamp with your own hands, it is enough to have on hand small remnants of a profile pipe, a hairpin, and, of course, bolts with nuts, which I think everyone has.
Visually, the clamp can be divided into two parts: the base and the clamping part.
First of all, we make the base from a professional pipe 25 * 60 as shown in the photo.
Base made of profile pipe 25*60
First, you can assemble it on tacks, then completely boil the seams and clean it well with a grinder.
Then, from the same pipe 25 * 60, we cut off two segments of 160 mm each and weld them along the edges. You only need to cook with outside and from the ends, because from inside the workpiece will be pressed and the seam may interfere.
We weld the outer jaws 90 degrees to each other.
The outer and inner clamps must be exactly 90 degrees to each other, after welding, make sure that they have not moved or been pulled away.
The next step is to make a mount for the clamping part.
We cut off a segment from a 40 * 40 pipe 30 mm long and cut off one of the sides, making it the letter "P", then weld it to the base. To fix the screw, we need to drill two holes for 8 and a third (lower) hole for 10, so that the socket wrench goes into it (you will understand why later).
We make a mount for the screw.
With the first part finished, now proceed to the second.
From the same pipe 25 * 60 we make internal clamps (sponges), on the outer sides I got 105 mm.
We press them with clamps to the external clamps and weld them together.
We make internal clamps.
We cut out two triangles 2 mm thick and weld to the internal clamps from above and below. We drill a through (in two triangles) hole at 8.
We weld two triangles and drill a hole.
To fasten the screw in one and the other parts, we weld nuts 8 and 14 together (as shown in the photo). We make two pairs.
We make a mount for the screw.
We screw one nut onto the screw, and for the second we need to prepare it.
We grind the screw in a circle a little more than the width of the nut and cut the thread at the end by 8. We put a washer on it, the main thing is that it be of a smaller diameter than the screw thread, put on a fastener welded from three nuts and tighten the bolt. The mount should rotate freely, and the groove was made so that during the rotation of the screw, the nut would not be screwed onto it, but would rotate freely.
Fastening to the moving part
After that, we fasten the screw to the clamping and main part and make a knob on it, also welded from nuts and a bar (or a long bolt). All the clamp is ready, it remains only to paint and put into action!
Do-it-yourself angle clamp - video
At the time of machining the workpieces to improve the quality, their reliable fixation should be carried out. Otherwise, the task is significantly more complicated, when working with hand tools, the surface may shift. Clamps, which are used for direct clamping and fixing the workpiece, are quite widespread. There are quite a number of different versions of clamps, the master's set often includes an angular one. To seriously reduce costs, the assembly of the mechanism is carried out from improvised materials.
What is an angle clamp?
In most cases, duralumin is used in the manufacture of the main part of the structure. That is why it is characterized by high strength. Ease of use is ensured by the presence of special fasteners. Among the features of the corner clamp, we note the following points:
- In most cases, the tool is used for frame-type parts, as well as various corners and similar structures.
- Often there is a situation when, during the assembly of furniture, individual elements are fixed. This is required when applying glue and carrying out other similar work.
Angle clamp is purchased for locksmiths and typesetters. At the same time, such equipment is also useful when working in a private workshop. Structural elements one can name the following:
- Clamp with two elements acting as a stop.
- A block that is characterized by increased mobility.
- Lever mechanism, due to which the transfer of high force is ensured.
- A screw that is used to clamp a moving part into position.
- Slider for fixture designed for weaker clamping of the workpiece.
Knowing the main elements of the corner clamp, you can make it yourself. In this case, the most various materials, most often a metal characterized by increased resistance to high humidity.
Clamp types
There are several types of clamps that can provide reliable fixation of workpieces. All of them are conditionally divided into three main categories:
- Simple ones are designed to fix the product relative to the working part of the workbench.
- Corner ones are characterized by a design that allows you to fix two parts relative to each other in the desired position.
- Volumetric are characterized by more complex design, which allows fixing three workpieces relative to each other in the required position.
The first type is characterized by a C-shape, which has a special bracket with a threaded clamp. The workpiece can be very different - plastic, wood, metal and many other materials. The second type is extremely common, as it is required to perform large jobs of the same type.
Factory fixtures are very expensive, but are characterized by higher operational characteristics. The corner version is made on the basis of a simple design. The main characteristics, as well as strength, largely depend on the type of material used.
Plywood clamps
When assembling furniture, chipboard sheets are often used, which are considered a very common material. They can be fixed relative to each other at a right angle. To carry out such work, a tool is required that can be assembled independently. A clamp is created from plywood using the following materials:
- The base is made using plywood or chipboard, thickness is about 8-12 mm.
- The emphasis is created by using a rectangular or square bar from various types of wood.
- You will also need a hacksaw to work.
- A drill with various drill bits is also required.
After finding all the required materials and tools, you can proceed to the direct assembly of the mechanism. The sequence of actions is as follows:
- Plywood is used to create two triangles with legs, the length of which is 30-40 cm. In this case, it is important to maintain an angle of 90 degrees between the sides of the triangle, since otherwise the resulting product will be characterized by low accuracy.
- A hole is drilled in each corner of the created blanks. Their size is selected in accordance with what clamps will be used.
Having created the product in question, you can begin to use a home-made design. Due to the use of a metal fixing element, high reliability of fastening is ensured, since even a slight displacement of the workpiece can lead to serious defects.
Angle clamps for metal workpieces
The use of a clamping device is also possible if it is necessary to ensure reliable fixation. metal elements. Also, for fastening metal parts, angle clamps are used, made using metal. This is due to the fact that metal blanks must be fixed more securely, since serious stress occurs during processing.
It should be borne in mind that a metal corner clamp is made in the same way as a wooden one.
It uses as a basis sheet metal, the thickness of which is 8-10 mm. To significantly increase the fastening, individual elements are welded.
Tool Benefits
The tool in question has a fairly large number of advantages. The main ones are the following:
- Long service life. As practice shows, an angle clamp can last for several years, the main thing is not to make a critical effort. Otherwise, there is a possibility of deformation of the main elements.
- The device is reliable. With the correct use of the fixture, the possibility of displacement of the workpieces is excluded.
- At the time of work, reliable fixation of the workpieces relative to each other is ensured. Due to this, the most favorable conditions for processing the workpiece are provided.
- Wide scope. In some cases, bonding is carried out, in others processing.
- Relatively low cost. Even industrial mechanisms are inexpensive. At the same time, there are simply a huge number of different versions on sale.
- The possibility of assembling the structure with your own hands. Due to this, you can significantly save money, since improvised materials are used during work. Homemade mechanism practically not inferior to the industrial one, it is also characterized by a wide range of applications.
In general, we can say that there are just a huge number of different advantages that determine the distribution of angle clamps.
Purpose
Angle clamp has become very widespread. At the same time, the main purpose is only one - fixing the workpieces relative to each other. Among the features we note the following:
- When machining, it is necessary to carry out reliable fixation. Otherwise, there is a possibility of a significant decrease in the quality of the resulting surface.
- The corner version provides strong pressure and secure fixation of the two elements when they are glued together.
The design of the clamp may vary slightly, it all depends on the specific case. When fixing fragile materials, an elastic gasket is used, which eliminates the possibility of damage to the surface layer.
Terms of use
There are several different rules regarding the use of the device. Among the features we note the following:
- Care must be taken to ensure that the surface is completely adjacent to the working part of the tool.
- When clamping, pay attention to the applied force. Too high a value causes damage to the surface layer.
- Do not forget that the angle clamp itself must also be securely fastened during the machining of the workpiece. Otherwise, the processing will be much more difficult.
The simplicity of the mechanism determines that it is quite simple to use it. It does not require any special skills.
How to make a carpentry clamp with your own hands step by step instructions with drawings?
If you need to reduce costs, a do-it-yourself corner clamp can be created from various improvised materials. On the Internet you can find a fairly large number of different drawings, according to which the device is assembled. It should be borne in mind that it is important to choose the right material. An angle clamp for welding can only be made using metal, since a hot alloy can damage wood. For the manufacture of an angle clamp, which will be used when assembling furniture, the following materials are required:
- Plate.
- Two bars.
- Bolts made of corrosion-resistant metal.
- Self-tapping screws.
- Some of the tools that are often found in the home kit.
For assembling furniture, a home-made design is only suitable when using soft sponges, which exclude the possibility of damage to the surface layer. The build instructions are as follows:
- Two long slats are placed on the desktop, one with an edge, the second with a wider part.
- Using a drill, several holes are created, which are required to connect individual elements.
- One of the plates is attached to the bottom of the bar, after which the second is fixed in parallel. You can adjust the gap using a self-tapping screw.
- A hole is drilled at the ends and a plate is attached to them. An angle of 90 degrees must be strictly maintained between the individual elements.
On the Internet you can find a drawing and specification that are used when self-manufacturing corner clamp. When considering how to make an angle clamp with your own hands, pay attention to the fact that all individual elements should be fixed relative to each other with high accuracy.
In conclusion, we note that it is practically impossible to do without the considered device. Moreover, it is inexpensive, can last for a long period. It is recommended to purchase metal with increased protection against moisture, as corrosion can significantly reduce the service life.
In this article, I will show you how you can make a simple 90° angle clamp for welding profiles and pipes. A good angle clamp in the store is quite expensive. The handmade angle clamp is 100% accurate, assembled from improvised materials and almost eternal.
Step 1: We collect all the necessary materials and cut the blanks
To assemble the right angle welder, I used a 0.47 x 0.47 cm steel angle and a steel strip. The corner is suitable, in principle, any, but I advise you to use thicker metal. I took 2 pieces of an angle piece 25 cm each, a steel strip cut into pieces 15 and 38 cm, the cuts were made at an angle of 45 ° on each side (the length of the short sides is given). You only need to arrange all the parts so that the clamp remains rigid after welding.
Step 2: Clamp Drawings
The top is open, I left 1.9 cm between the inner edges. This gap allows you to combine the pipes in the center and approach them by welding. A gap of less than 2.5 cm leaves versatility in use, with a gap of more than 2.5 cm, a pipe can already slip into it when welding.
In the photo - a top view, from this side it is not necessary to cook! All seams must be done from the bottom side, only this way they will not interfere either when using the top side or when using the bottom.
Step 3: Assemble the Clamp and Check the Angle
After sanding the metal surface, assemble the angle clamp with 4 regular clamps. Check the inner corner for accuracy with a metal square. With the exact coincidence of the sides of the square with the sides of the clamp, the square should not play at all.
Step 4: Start welding from the back
Once you have your clamp assembled, turn it over and start tack welding with reverse side. First, I boiled one side and let it cool. The side must be done immediately completely so that the parts do not move relative to each other.
After the welding of one side is completed, turn the clamp over and check the angle again. Then we grab the other side. After that, we check the angle again. It is very important to allow the metal to cool between welding the two sides. Then you can compensate for the angle error if the metal leads when welding. Do not remove the C-clamps until the angle clamp is finished.
Although I have made such devices before, when making this particular one, I found an angle error when checking with a square after welding one side. I simply cut the tacks, and reattached the steel parts with C-clamps. After that, the angle turned out to be straight, as it should be.
Step 5: Finish Welding
After welding is completed, we check the correctness of the right angle with different squares. Sometimes it happens that the square has led and its angle is no longer straight. Therefore, it is better to play it safe and check the right angle with different squares. Please note that the photo shows that I cut off the protruding outer corners of the lower crossbar. After welding, I simply sanded the entire surface with a petal wheel.
How to fix a wrong angle
If the angle doesn't come out exactly 90°, or if she's moved after falling off the workbench, it can be corrected. First you need to find dents in the metal. In any dent, you can simply put a clamp welding machine. Then place a straight piece of metal into the clamp and check the angle with a square. Level the clamp with a file until the angle is equal to 90°.
Step 6: Angle clamp in action
A homemade corner clamp can be used both outside and inside. That is why all the welds are made on the underside. The photo shows examples of use, if I were going to weld these pipes, I would additionally secure them with ordinary clamps. The last photo shows an example of adding a vertical element. This also explains why the gap between the arms should not be too large - otherwise the vertical pipe would slip into the hole.
Be careful when welding pipes externally - the inside bend radius of the elbow can interfere with clamping the pipe with a clamp. Be sure to check this point before you start welding pipes.
At first glance, fairly simple welding work usually requires a responsible professional approach. To obtain the highest quality results, it is necessary to additionally use special tools, fixtures, one of which is an angle clamp for welding, made by hand according to the drawings. With such a tool, welded joints metal products performed much faster and easier.
Clamp- This is a universal device that is suitable for any kind of work with metal structures. The tool is one of the most important accessories for experienced welders. Its absence leads to inconvenience in the performance of work, respectively, a decrease in labor productivity.
Clamps for welding are manufactured in a wide variety of parameters, they can have a constant or adjustable throat size. Quick clamps are very convenient when clamping metal samples is carried out by means of a cam mechanism.
It is easy to make welding fixtures yourself at home. Many craftsmen believe that various devices used for the convenience of welding, purchased in a store, do not differ in the necessary reliability. It is better to make them by hand.
To make such a tool, you will need the following components:
- steel sheet, thickness 9-11 mm;
- nuts - 3 pieces;
- large diameter washer;
- a pipe blank, which must have an external thread similar to the thread of a nut.
Manufacturing instructions
The scheme for making a clamp at home looks something like this:
- First of all, it is necessary to cut 3 strips of different lengths from a metal sheet - 10, 25, 50 cm, the same width - 4 cm.
- Next, we prepare 2 rectangular plates, which will be needed to fasten the moving part, resting on the static section of the fixture.
- We weld the auxiliary to the base of the clamp. By connecting all of the listed elements, you should get an L-shaped design.
- The next rectangular sheet is welded to the smaller side of the fixture, the washers are welded together.
- We apply nuts to the movable structural element (we put them “on edge”). In this case, the unscrewed rod to the base of the clamp must be parallel.
- Welding is carried out from the outside of the first rectangular sheet. And the movable mechanism is attached from the inside along the edges.
- The last stage in the manufacture of the clamp is to weld the washers flat to the rod.
A do-it-yourself device makes it possible to hold overall structures made of pipe-rolling parts without the slightest shift.
Angle clamp
The corner fixture is a universal fixing device that is used to fasten and hold products when they are welded. Such an auxiliary mechanism compresses the parts firmly enough at a set angle, which greatly facilitates the work of the welder.
Clamps are made different shapes, sizes. The most convenient option is quick-clamping devices.
For constant welding work, it is recommended to have full set excellent in design, tool parameters.
Angle clamp design
Such devices allow you to weld metal products not only at a right angle. Factory fixtures are made in several modifications, they can be used to connect pipes at different angles - 30-90º.
Features of angular type devices:
- clamping jaws are made of greater thickness, due to which the degree of rigidity of the joints of parts increases, the welding seam does not bend during welding;
- additionally, copper clamping screws are used, which do not allow soldering of the threaded sections of the clamp when they are splashed with molten metal, respectively, increase the operating period of the equipment;
- to perform welding with electrodes at set angles in the areas where products are joined, the clamp makes the working area larger.
The design of the device is a base in the form of a frame and a movable mechanism. The movable part of the device is often additionally equipped with a clamping lever (screw), which allows you to adjust the degree of compression of the products.
Due to its good mobility, the device is able to fix metal products of various sections and parameters. For the most comfortable welding, increasing productivity, you can use several of these devices of different configurations at the same time. Most of the tools produced are designed for welding metal samples with a diameter of up to 39 cm.
On corner clamps for welding, special T-shaped handles are provided, which make it possible to transfer the force generated during work to the workpieces. And staples made of cast iron can withstand the highest temperatures.
When choosing an angle clamp, it is necessary to take into account the type of work to be done. For example:
- G-clamps are most often used to securely hold metal specimens that are thin.
- F-clamps with adjustable clamping mechanism are used when processing thick metal specimens.
Quick-clamping devices can be mounted in a garage, workshop, and other premises on desktops that have a flat surface.
