SUBMERGED WELDING WITH PULS ARC

, 2022
The features of submerged arc welding with a pulsed arc (SWPA) have been studied. It is shown that an appropriate choice of SWPA parameters makes it possible to change the flows distribution in the weld pool and the thermal cycle characteristics of welding. With a constant heat welding input, the welds made by SWPA have a 20 ... 25% greater penetration

Laser Beam Submerged Arc Hybrid Welding

Physics Procedia, 2012
AbstractThe laser beam-submerged arc hybrid welding method originates from the knowledge that, with increasing penetration depth, the laser beam process has a tendency to pore formation in the lower weld regions. The coupling with the energy-efficient submerged-arc process improves degassing and reduces the tendency to pore formation.
