Chapter 3 Welding Joints, Positions, and Symbols 71 Figure 3-47. Travel angles on a groove weld. Push travel angles, or forehand welding, has the fl ame, gun, or electrode pointing in the direction of travel. Drag travel angles, or backhand welding, has the fl ame, gun, or electrode pointing opposite the direction of travel. Perpendicular to weld axis Push travel angle Plane defined by weld axis and electrode axis Weld axis Electrode axis Drag travel angle Figure 3-48. Travel and work angles on a fi llet weld. Work angles can range from to 0° to 90°. Typical work angles for fi llet welds are 30° to 60° and would be measured from the vertical piece in this illustration. Perpendicular to weld axis Drag travel angle Weld axis Plane defined by weld axis and electrode axis Push travel angle
