Laser Beam Submerged Arc Hybrid Welding

open access: yesPhysics Procedia, 2011
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 combination with the energy efficient submerged arc process improves the degassing and reduces the tendency to pore formation.
