Seemingly simple welding work, as a rule, requires a fairly professional and responsible approach. Because to perform high-quality and reliable work, you will need special tools. Such a tool can be an angle clamp for welding, which makes it possible to carry out welding work much easier and faster.
An angle clamp is a kind of universal clamp that holds the surfaces being processed during welding. Such a device firmly compresses the necessary elements at a certain angle and thereby makes the process of welding and processing materials more convenient . This is the first most important equipment for any welder, and it is impossible to do without it without causing damage to productivity and extreme inconvenience in work. Clamps can come in different sizes and shapes. Quick-release options are considered especially convenient. In general, for constant welding work, professionals recommend having a set of clamps of different configurations.
Options for 90 degree clamps for welding
With the help of modern 90-degree equipment, preparation for welding and assembly work is simplified and facilitated as much as possible.
- Professional clamp.
A standard professional tool will provide fast, strong and precise fixation of various welding elements at the same time. This mechanism is easily adjusted and easily dismantled, saving working time. This is the main advantage of the equipment.
The welding tool is made of blued metal. When ordering a product, it can be delivered in separate parts, and the dimensions of the ordered elements can be specified individually. The existing horizontal bar is height adjustable using a lock located on the cross. Clamping pressure can be set and controlled by turning the hexagon on the handle with a suitable wrench.

- Professional XL class clamp.
The tool is an improved version of the standard tool for applications where increased clamping pressure is required during the welding process. The material for making the equipment is blued iron 35x14 mm.
Like the standard professional model, it is also possible to order vertical and horizontal elements separately and according to individual sizes.
- Professional clamp with 360 degree rotation.
This tool is unique in that it can work in a full circle range, while the usual standard mechanism is limited in rotation by 45 or 90 degrees. In other words, here the movable bar is fixed at absolutely any angle. The clamping force can also be adjusted by turning the recessed hex nut located at the top of the handle. This model is made of blued iron 30x14 mm.
- Quick-release professional clamp.
Designed for quick and reliable fixation of workpieces during welding. The clamping force is adjusted by changing the distance to the existing system holes. The quick-clamping mechanism itself is located on a horizontal bar, which, like the hardened vertical bar, can be made to individual sizes.
The vertical element has a circular cross-section of 28 mm. The standard length of the strip can be 300, 500 and 800 mm. The package also includes two types of cast iron crosses without a wing, 67 and 69 mm, respectively. During the production process, the element is hardened.
- Professional clamp equipped with a cam clamp.
It also ensures strong and quick clamping of parts to be welded thanks to the vertical clamp located at the top of the tool. A similar clamping mechanism can be equipped with both standard professional equipment and a tool with a movable bar at 45 and 90 degrees.
- Quick-release standard clamp.
It has a very simple design with a precise locking mechanism that provides fairly strong and fast clamping of workpieces. Products are available in several standard sizes in the length range 200–400 mm.
- Universal clamp for welding.
This device successfully combines the useful qualities of a standard tool and the mobility of the equipment at 45 and 90 degrees. The result was a flexible clamp with a bar that moved in the range from -42 to 42 degrees. The position of the movable bar can be changed by rotating the corresponding screw. This ensures flexible fixation. The latter can be either straight or at an angle of several degrees.
The position of the horizontal round bar, 200 mm long, is also adjustable. Together with the rotating screw, this feature offers more options for positioning the tool. The structure of moving elements is placed on a vertical tube 250 mm long, fixed with a special ring in the hole of the welding table. The kit also includes a 135mm threaded screw.
- Basic screw clamp for 90 degree welding.
Used for quick and accurate fixation of parts at a strictly right angle. The device itself can rotate 360 degrees, which makes it possible to install it on the table in any position. The vertical bar is fixed in the hole of the welding table with an existing ring.
- Basic 180 degree screw clamp.
It differs from the previous type in that it fixes the workpieces at an angle of 180 degrees to the table holes. The adjustment range in the horizontal plane is 45–180 mm from the vertical element. The length of the tool screw is 100 mm.
- Quick-release clamp with adapter.
The built-in adapter allows the tool to be used in any hole in Type 28 welding tables. The combination of this tool with a stop makes its use as flexible as possible.
- Quick-release horizontal clamp with adapter.
Equipped with a removable adapter, which makes it possible to use a horizontal clamp on tables of type 28. The universal stop provides the design with maximum functionality.
- Quick-release clamp for welding at 100 and 160 degrees.
This device can also be used in any holes of type 28 welding tables. The degree of pressure within a certain range is adjusted by the corresponding screw.
- Basic clamp.
Designed to work exclusively on type 16 welding and assembly tables. The mechanism is quite simple, but at the same time provides reliable fixation. The distance between the tool and the workpiece can be changed by rotating it. This equipment can be used to fix products made of different materials, for which it is necessary to change the prism.
- Clamp with a round tube.
This tool is also designed for type 16 tables. It is easy to adjust, easy to use, and has a long service life. It is possible to order vertical and horizontal elements separately according to individual sizes. Thanks to the presence of a replaceable prism, workpieces made of different materials can be processed.
Classification of devices
Usually they use a trivial classification, according to which all tools for welding are divided into installation and fastening. Installation tools help to adjust the makers with the required degree of accuracy. Classic devices include squares, stops, and templates.
Fastening devices provide fixation of parts in the installed position; these are clamps, ties or spacers.
DIY F-shaped version
To make such a clamp, any scraps of profile metal are suitable. You will also need a nut, a screw, and some mounting bolts. The whole process is conventionally divided into two stages.
- The first step is to make the foundation. There are no special requirements for the profile, but as an example, you can consider a base made of a 25x60 mm pipe. You need to make three blanks with a length of 100, 200 and 300 mm. If you decide to make a clamp with fixed jaws, then the blanks are assembled in the shape of the letter “F” and a nut is welded to the end of the middle part. After making the screw with the clamp, the clamp will be ready.
- To make a clamp with a movable jaw, it is necessary to ensure free movement of the middle part along the base. Using a grinder and a welding machine, in any available way, make a mandrel for the middle part, which is loosely put on the long part of the base.
The clamp is made from a part of a screw with a plate at the end. For convenient use, you need to make a handle. The most trivial method of making a clamp with an adjustable jaw is described, but the movable jaw is not fixed. The fact is that when the screw rotates, a redistribution of forces occurs such that the middle part (the movable jaw) becomes slightly skewed on the base, which prevents it from moving. This type of clamp is considered self-locking.
Where can I buy
The clamps themselves are not a rare commodity, so there are usually no difficulties in purchasing them. Let us highlight just a few features of the purchase that may be of interest to the consumer.
First of all, clamps of various sizes can be found in specialized stores that sell tools. Indeed, there is no strict gradation for certain types of work, so welding clamps can also be purchased in the department of tools for carpentry.
However, it should be remembered that the tool must be made of metal. No wooden or plastic elements are allowed.
The jaws and threaded part must be strong, since when fixing metal products they bear a large load.
On the official website of the welding equipment manufacturer there is a section that allows you to organize the purchase of products online. If there are clamps in the catalog, you can buy them from an official distributor or directly from the manufacturer. This purchasing method is considered the most acceptable, since the proposed clamps are most likely adapted specifically for welding work.
You can also buy clamps in an online store not related to welding activities. In this case, the customer is at risk, since it is impossible to assess the quality of the mechanism and material from the description alone. The first two methods are the most acceptable.
