ABSTRACT:
A method of joining together two relatively thin work pieces by arc welding is disclosed. The work pieces are rotated relative to a welding electrode so that the welding electrode is moved at relatively high speed over a path of contact between the work pieces where the weld is to be made. The power density at the work pieces is controlled so that it is necessary to make several passes of the electrode over the path of contact between the work pieces to make the weld. This welding procedure produces a weld of high quality without the use of complex current programming which is required when using conventional arc welding procedures.
