ABSTRACT:
A welding apparatus and method for forming arc welds of thin sheet material. The apparatus forms a first pool of molten material and then discontinues the welding to permit a portion of that pool to solidify and then reestablishes a new arc at point along the periphery of the solidified previous pool and continuing this operation to form the finished weld bead. Thus, lower welding heats may be employed and greater tolerance in the welding method and apparatus is possible.
