What should be the thickness of steel backing on a weld?
Steel backing on welds transverse to the stress direction should be removed and the joint ground flat. Otherwise, the weld could be prone to cracking as shown in Figure 11b. Backing has a recommended minimum thickness to prevent melt-through. For example, for SMAW it is 3/16 inches.See all results for this questionWhat kind of pipe is double submerged arc welded?Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications.
