  • The most effective as well as most economical welding procedure for the welding hollow cylindrical parts


  • Welding head with linear motor
  • Integrated process control for quality assurance
  • PC-controlled
  • Welding time approx. 800 msec with dia. 30 mm


  • Minimum plate thickness ≈ 1 mm, maximum plate thickness ≈ 4 mm
  • Minimum wall thickness of pad in the welding section ≈ 1 mm
  • Welding of end caps on pipes
  • Gas tight to over 250 bar (M10)


  • Even and minimal heat input (low distortion)
  • Very short welding time (≤1 second) and consequently short cycle time in production
  • No welding commodities required
  • Minimum upsetting force
  • Small and even welding collar
  • Only one-sided accessibility to the work piece required
  • No reworking of work piece or welding element (thread)
