Quizplus · Accepted Answer

Filler metal is used in gas welding to help join two pieces of metal together. In gas welding, a flame is used to melt the base metals, and the filler metal is added to the molten pool to form a strong joint upon cooling. Spot welding, seam welding, and projection welding typically do not use filler metal; instead, they rely on the fusion of the parts being welded through the application of pressure and heat.
