Describe how the correct diameter of filler metal will help control the weld bead width, buildup, and penetration.
What will be an ideal response?
Selecting the proper size or correct diameter of filler metal will help control the weld bead width, buildup, and penetration. A large diameter filler rod can be used as a heat sink (something to draw off excessive heat) to keep the molten weld pool narrow, with little penetration and high buildup. As the diameter of the filler wire is decreased, the heat-absorbing effect decreases, and the molten weld pool becomes wider, with deeper penetration and reduced buildup. On thin metal, it may be necessary to use a large diameter filler rod to control burn-through. On thick metal, a small diameter filler rod may be used to increase penetration.
