The angle less than 90 degrees between a line perpendicular to the major workpiece sugace and a plane determined by the electrode axis and the weld axis. In a T-joint or a corner joint, the line is perpendicular to the nonbutting membel: This angle can also be used to partially define the position of guns, torches, rods, and beams. See DRAG ANGLE, PUSH ANGLE, and TRAVEL ANGLE.
