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.
