The angle less than 90 degrees between the electrode axis and a line perpendicular to the weld axis at its point of intersection with the extension of the electrode axis, in a plane determined by the electrode axis and a line tangent to the pipe sugace at the same point. This angle can also be used to partially define the position of guns, torches, rods, and beams. See Figure T-19. See also DRAG ANGLE, PUSH ANGLE, and WORK ANGLE.
