Friction Stir Welding Without Filler or Shielding Gas

What this page covers

• Solid-state welding with no filler material and no shielding gas
• Heat-sensitive materials including aluminium, copper and magnesium alloys
• Dissimilar metal joints such as aluminium to copper and aluminium to magnesium
• Aerospace, new-energy vehicles, battery housings and electronic heat sinks as application directions

What to confirm before ordering

Because the base metal is not melted, distortion and heat damage are lower than in fusion welding. That makes the route attractive for thin or heat-sensitive assemblies. Before ordering, confirm minimum order quantity and lead time for your drawings.

Drawing checklist

Send the drawing with units and scale stated, the material and grade, the critical dimensions and tolerances marked, and the finish required. State the quantity you need checked and the question the part must answer: fit, function or appearance. Uploaded files are used only for the quotation, and non-disclosure agreements are supported.

Quality checks

Parts are inspected with a coordinate measuring machine, a projector and height gauges, with quality control at each production stage, and a dimension report can be provided for a project on request.
