This model 120V, 14 ton (28K lb max., 124.54 kN max.) forge force, vertically configured, inertia friction welder has an 3,000 max. RPM rating and can weld 1.7 in sq (1,097 mm sq) max. tubular area. This vertical spindle hybrid inertia friction welder joins the steel halves of an airbag gas generator cartridge that is filled with propellant (not shown).
Rotary Friction Welding is a solid-state process in which one part is rotated at high speed and is pressed against another part that is held stationary. The resulting friction heats the parts, causing them to forge together.
