FRICTION STIR SPOT WELDING

For low-temperature applications, the friction stir spot welding tool is available as a single solid tungsten carbide unit.

For higher temperature steel applications, the friction stir spot welding tool comes with a smaller steel tool holder and with separate tips with PCBN and CMM tips.

Optimizing tool geometry to produce more heat or achieve more efficient “stirring” offers two main benefits: improved breaking and mixing of the oxide layer and more efficient heat generation, yielding higher welding speeds and, of course, enhanced quality.

The simple pin-shaped, nonprofiled tool creates frictional heat and is very useful if enough downforce can be applied.
