This RSR weld yields higher strengths than traditional spot welds of the materials themselves, with the flexibility to join nearly any combination of steel and aluminium sheets or extrusions a vehicle designer may need.
Welding and fastening expertise yields RSR™ The ideal, most economical joining technology in a mixed material world, would seemingly be some hybrid of welding and mechanical fastening.
As these material classes become mainstream, new joining methods must be developed, commercialised, and validated.RSR upgrades and empowers existing capital Rather than gutting stamping and spot welding cells to replace them with drilling, assembling, and joining cells,
RSR is a small addition that can be made to spot welding guns, while still allowing for backwards compatibilityto steel spot welding.Additionally, the trend for joining advanced aluminium to itself, and ultra-high strength steel, is limited by the formability required for mechanical fastening.
