Properties
Friction stir welding

Process

• Wide range of weldable thicknesses from a few millimeters to 100 mm.

• Preparation by mechanical machining with low precision (10% thickness deviation permissible).

• Butt-jointed sheets without chamfer.

• No chemical pickling before welding for light alloys.

• Possibility of welding different materials.

• Welding in a single pass over the entire thickness, or in two opposing passes for thicker sheets.

• No consumables, filler metal or gas shielding.

• Corner and "T" welding.

• Overlap and clinch welding.

• Welding in any position.

• Simplified production of difficult assemblies using...
