Joints and seams
Joints for welding must not have any gaps and must be made carefully.
If a burr is created during filing, this can be used as additional material for welding.
Preparation
Joints that are to be filled must be well finished and must not have any gaps, otherwise additional material must be used.
If a burr is created during filing, this can be welded in very well as additional material
Metal
The metal should be so thin that it can be penetrated at least 2/3 of the way through with a spot weld so that there is no cavity on the opposite side after welding.
Use welding wire
If the joint is not optimally prepared, a indentation may occur during welding, which may then have to be filled with wire filler.
If the workpiece is too thick, a V-joint should be created.
This is then filled layer by layer with a welding wire of the same alloy.
The welding wire should not be thicker than 0.4 mm
Stapling
First tack the parts together with one or two spot welds.
You can then adjust the angle and concentrate the seam welding wire.
Start welding
Always hold the handpiece at a right angle to the workpiece to achieve the best penetration depth and stability.
Always place the electrode on the edge of the previous welding spot so that the spots overlap.
Make sure that less welding power is required in the edge areas than on surfaces.
To prevent the edges from melting off, hold a piece of metal of the same alloy next to the seam so that it absorbs the excess energy.
Pulse time
You can always weld seams with different power levels.
The higher the power, the larger the welding points.
This is faster, but causes more work when trimming.
For joints that you can only weld from one side or for thicker material, you can weld with a slightly longer pulse to improve the penetration depth.
To do this, however, the parts must first be completely sealed with the normal pulse time
Seal holes
Small holes in the joint can be plugged by inserting the electrode vertically from above.
Larger holes are best closed by moving the electrode across the hole, placing it against the previous welding point and pulling the hole closed.
