222 Modern Welding Copyright Goodheart-Willcox Co., Inc. Uphill welding uses the oval weave or a Z-weave pattern. Weaving creates a wider and flatter weld bead than a stringer bead. See Figure 8-47. There are other weave patterns, but these are the most com- monly used. Practice and develop the feel for each weave tech- nique. Find the one that is comfortable for you and that produces a quality weld bead. All of these weave techniques can be used with both forehand (push) and backhand (pull) travel angles. A B C D E F G Goodheart-Willcox Publisher Figure 8-46. GMAW weld beads. A—Proper current, arc length, and travel speed. B—Current is too low. Bead is narrow. C—Current is too high. Bead is wide with some spatter. D—Nozzle-to-work distance is too long. Bead is inconsistent, narrow, has poor melting at the weld t oe, and has excessive spatter. E—Nozzle-to-work distance is too short. Bead is a little narrow with low reinforcement. F—Travel speed is too slow. Weld bead is very wide with a lot of reinforcement. G—Travel speed is too fast. Weld bead is narrow and has poor melting at the toe of the bead.
