... Abstract Hybrid laser arc welding (HLAW) is a metal joining process that combines laser beam welding (LBW) and arc welding in the same weld pool. This article provides a discussion on the major process variables for two modes of operation of HLAW, namely, stabilization mode and penetration mode...

... and laser-arc hybrid welds ( Ref 13 , 15 – 17 ). Without careful control of keyhole-mode melting, keyholes can become unstable and repeatedly form and collapse, leaving voids inside the deposit that consist of entrapped vapor ( Ref 18 ). The root of keyhole porosity is initiated by the generation of a deep...
