Spot welding
Spot welding joins sheet parts point by point, without filler material. It is quick and leaves little to see on the outside.
How it works
Two electrodes clamp the sheets together and briefly pass a high current through them. The material melts exactly at the contact face and the sheets fuse there.
Where it fits
Spot welding suits overlapping sheet parts where a continuous weld is not needed: enclosures, panels and assemblies where the visible finish matters.
Which materials
Spot welding is done in steel, stainless steel and aluminium. Each of those asks for its own combination of current, time and electrode force; which plate thicknesses are feasible in your case depends on the part.

How does spot welding work?
Two electrodes clamp the sheets together and briefly pass a high current through them. The material melts exactly at the contact face and the sheets fuse there. No filler material is needed, and instead of a continuous weld the joint is made point by point.
Which materials and plate thicknesses can be spot welded?

What we need to quote
If something is missing we will ask. If you are not sure yet yourself, we will look at it with you.
- material and thickness
- the quantities involved
- a drawing: DXF, STEP or a dimensioned PDF
- whether the part still needs finishing or assembly
