Sapa Extrusions North America announces the completion of a joint development project with H.F. Webster Inc. that extends Sapa's friction stir welding capabilities.

  • Uses frictional heat and mechanical mixing to join aluminum materials
  • Creates a stronger, lighter bond with consistent weld properties without distortion from heat input and emissions from traditional arc welding
  • Offers improved ductility, fracture strengths and toughness
  • Allows production of two-sided welds up to 55 ft. long with expansion capability to 75 ft. long in aluminum material as much as 30mm thick
