What are the implications of welding over

Even though welds on welds are common, there are nevertheless some potential concerns. Of particular importance are any differences between the welding procedures of the two overlapping welds. If the heat inputs are different, such as when a multi-pass girth weld overlaps a single-pass seam weld, the cooling rate of the weld metal in the two cases will be different. Thus the weld metal, which
