Explain why the use of GMA welding can help reduce waste of filler metals.
What will be an ideal response?
GMA welding's 98% deposition rate of filler metal into the weld makes it one of the most efficient welding processes. Filler metal carries a high cost when it does not get deposited into the weld because of spatter or electrode stubs and becomes wasted material. Using GMA welding will reduce waste.
