Quality control in welding is the responsibility of everyone involved in welded fabrication—from the selection of the proper aluminum alloys and forms of welding, to proper metal storage, selection of the joint design and method of edge preparation, selection of the welding process, equipment and filler alloy, establishment of the welding procedure, adequate training of personnel and supervision involved with the welding operations as well as the final weld inspection. Too much emphasis cannot be placed on making a satisfactory weld since repair welding is expensive.

This paper reviews the discontinuities normally encountered in aluminum arc welds, the methods used to detect the weld faults, the possible causes of the discontinuities and means to avoid them.
