Spot welding sheet metal delivers neat, durable joints with minimal distortion in the 0.15-1.0 mm range across galvanized steel, stainless steel, titanium-zinc, aluminium, copper and brass.
From short runs to continuous production for construction – ideal for joining flanges, brackets, hems and overlaps without drilling or additional fasteners.
Scope and Applications
Spot welding sheet metal is a fast, repeatable, and cost-effective joining method that delivers neat joints with minimal distortion of the base material. We handle short production runs as well as continuous manufacturing for sectors such as construction and industrial fabrication. This process is ideal for joining flanges, brackets, hems, and overlaps in thin sheet components without drilling or additional fasteners.
Materials and Thicknesses
Our spot welding process covers a wide range of metals and coatings to meet your specification and end-use requirements.We work with:
Galvanized steel, stainless steel, and titanium-zinc
Aluminium, copper, and brass for non-ferrous applications
Typical sheet thickness range: 0.15–1.0 mm, including multi-sheet stack-ups in various configurations.
Quality and Process Control
Joint durability is ensured through precise selection of squeeze force, current, and weld time, tailored to each geometry and alloy. For every project, we prepare a parameter card, verify nugget size and point spacing, and record test results for full traceability. Our quality control includes visual inspections, peel tests, and routine sampling, supported by calibrated stations and scheduled electrode maintenance.
Process and Parameters
Depending on the alloy and part geometry, we select the optimal electrode tip form and material to distribute heat efficiently and limit the heat-affected zone (HAZ). Controlled upslope and optimized weld pulse duration reduce spatter and surface discoloration, ensuring excellent cosmetic results. We adjust squeeze force and point sequence to maintain dimensional accuracy and stable clamping throughout the process.

FAQ – Spot Welding Sheet Metal
What tolerances are achievable?
Dimensional stability depends on part geometry and point sequence – controlled energy input and squeeze force maintain tolerances in thin-sheet production.
Is spot welding suitable for visible parts?
Yes – with proper electrode selection and parameter control, surface marks are minimized, making it ideal for cosmetic applications.
What material combinations are typical?
Common pairs: steel–steel, galvanized steel–steel, stainless steel–stainless steel, and aluminium–aluminium. Other stacks can be validated through trials.
Do you work with customer-supplied materials?
Yes – we accept consigned materials with full batch identification and quality documentation upon request.
Have a project that requires durable, neat joints in thin sheet?
Send drawings and expected volumes – parameters and a quote will be prepared promptly, and the team will recommend the best stack-up for your part.
