Friction Stir Welding for Low-Temperature

Friction stir welding for low-melting-point metals, such as aluminum and aluminum alloys, has been used in the aerospace, marine, and transportation industries for many years. Benefits include low distortion, greater weld strength, little or no porosity, no filler metals, little or no postweld repair, no solidification cracking, no welding fumes or gases, improved corrosion resistance, and lower cost in production applications. The process uses tools made from hardened tool steels that are inexpensive to fabricate. Tool steels provide sufficient hardness and abrasion resistance at these temperatures.

A Series

Excellent option for higher strength or thicker aluminum welds with adjustable pins.

H Series

Solid, one-piece tool made from H13 offers all-around good wear.
