Work Angle
The angle less than 90 degrees between a line that is perpendicular to the cylindrical pipe surface at the point of intersection of the weld axis and the extension of the electrode axis, and a plane determined by the electrode axis and a line tangent to the pipe at the same point. In a Tjoint, the line is perpendicular to the nonbutting member. This angle can also be used to partially define the position of guns, torches, rods and beams.
