HBS-MARC-3

Pad Welding Machine PC-M3 for pad welding with rotating arc.
 

Application

 

  • The most innovative process for welding pad type elements
  • To be used for nearly any application in metal working industry: The very low heat input avoids any distortion of the work piece and you get a perfect gas-tight weld with high and dynamic loading capacity
  • The most effective as well as most economical welding procedure for the welding hollow cylindrical parts
  • Closed and pressure sealed weld all-over
  • The welding requirements are manifold, reaching from the simplest static firmness to dynamic demanded gas tight connections at high temperature and pressure
  • Austenitic stainless steel (1.4301 and similar), low alloys (RSt 37-2 / S 235J2G3)
  • High productivity together with low manufacturing costs
  • No need for additional welding cons
  • Free programmable welding head

 

Process variants

 

  • Pad welding with magnetic rotating arc
