Chapter 3 Welding Joints, Positions, and Symbols 69 Figure 3-44. Travel angle in a groove weld. The travel angle is measured from the electrode axis to a line perpendicular to the weld axis in the plane defi ned by the weld axis and the electrode axis. A—The weld axis and a line perpendicular to the weld axis are shown. B—The plane determined by the weld axis and the electrode axis is shown. C—The travel angle is shown.
