ABSTRACT:
A method and system for multiple pass welding that includes a welding torch mounted on the arm of an industrial robot. The robot has a data processor with a memory and the coordinates of a first path are inputted to the data processor and are stored in the memory. The welding torch is then moved along the first path by the robot to make a first weld of a workpiece (or workpieces). A second weld of the workpiece is made by moving the welding torch along a second path which is offset from the first by a predetermined positional increment. The positional increment is established by positional coordinate increments which are inputted to the data processor by a robot user before or after the first weld has been made. The user may also input a weld torch angle increment to change the angle of the welding torch with respect to the first path. Subsequent welding passes are made by moving the welding torch along additional paths which are also offset from the first path.
