Combining LBW and GMAW results in which significant enhancement?
A) Decreased GMA welding speed
B) Improved strength, ductility, corrosion tolerance, and machinability
C) Reduced weld reinforcement
D) Increased slag

Question

Quizplus · Accepted Answer

Combining LBW (Laser Beam Welding) and GMAW (Gas Metal Arc Welding) results in improved strength, ductility, corrosion tolerance, and machinability. This is due to the high energy density of LBW that results in deep penetration and minimal heat input, while the filler material used in GMAW provides additional strength and ductility to the weld.
