Spot Welding

Reliable resistance welds at production speed — pedestal and robotic cells for sheet metal assemblies up to 6 mm combined thickness.

Resistance spot welding joins overlapping sheet metal components with minimal heat distortion and no filler material. Pedestal machines handle single-point production work, while robotic spot welding cells deliver consistent multi-point welds on higher-volume assemblies. Weld schedules are programmed and locked for each joint to guarantee nugget size and pull-through strength on every part.

Frequently Asked Questions

We perform peel and chisel tests on the first-off and at set intervals. Weld schedules log current, time and force per joint for traceability.
Yes — we adjust electrode force and current for galvanised coatings and use regular tip dressing to maintain contact quality.
Up to 6 mm combined (e.g. 3 mm + 3 mm). For thicker or dissimilar thickness stacks, we assess weldability before quoting.
