How to make a welding clamp for any welding angle

To quickly and evenly weld pipes, rods and other rolled metal at an angle, it is very convenient to use a special clamp. It holds parts stronger than magnets, and is also capable of being adjusted to different joining angles. This is a really useful device for a welder, which is not difficult to make yourself.

Basic materials:

• pipe 100 mm;
  
• corner 50x50 mm;
  
• strip 50 mm;
  
• M16 studs – 2 pcs.;
  
• bolts M10, M16;
  
• regular and extended nuts, washers M10, M16, M20.

The process of making a clamp for welding

You need to cut a piece 7-10 cm long from the pipe. A cutout 16 mm wide is made in the center, halfway around the circle.


Next you need to prepare 2 pieces of angle along the length of the pipe. An M16 bolt with a machined head is welded into the center of one of them.

The angle with the bolt is inserted into the slot in the pipe. From the inside, an M20 nut is put on it and an M16 is screwed on.

You need to move the corner to the edge of the groove and clamp it. Then a second one is placed close to it and welded to the pipe.

Strips 15 cm long are welded to the corners at right angles. It is important that the metal does not bend during welding and that the angle is maintained.

At the next stage, 2 stops are made for clamping the clamp. To do this, 2 rings are cut from a 3/4 inch tube.

Washers are welded to their sides. On one side you need to weld a small washer so that the head of the M10 bolt does not pass through it.

To make the clamp you need to prepare 2 M16 studs. A head is welded to them at one end; M20 nuts can be used as it.

From the second one, M10 nuts are welded to the end. The latter are machined in order to screw extended M16 nuts onto the studs.


The stops are screwed to the studs with M10 bolts.

Next you need to weld them with elongated nuts to the strips at the corners. For this purpose, spacers made of rods are used.

After welding, the clamp is painted.

Its movable corner must be installed exactly opposite the welded one in order to maintain a right angle. Then marks are made on the pipe with a hacksaw along its edges. After this, you should move the moving angle to 45 degrees, and also put notches.

Based on the marks, it will be possible to set the clamp at the desired angle and clamp pipes or other rolled products on it for welding. The result is a very convenient, useful design that allows you to weld even metal structures.
