Welding systems with magnetically moved arc – Institute of Materials Science

Welding systems with magnetically moved arc (MBL)

Pressure welding with a magnetically moved arc allows the end-face joining of hollow profiles. An arc is ignited between the joining partners and set in rotation by means of an externally applied magnetic field. The arc rotation ensures uniform heating and melting of the joining zone. The joint is joined by defined pressing.

KUKA H5000/1000

The KUKA H5000/1000 system for welding with the magnetically moved arc was retrofitted at the Institute of Materials Science. The system allows MBP welding processes with up to five controlled process phases and complete recording and documentation of all relevant process variables during the welding process.
