HBS-MARC-3
Pad Welding Machine PC-M3Â 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
