WPSAmerica.com AWS D1.1 (Structural Welding Code-Steel) 5-Guide (Preheat) The need for and the temperature of preheat are dependent upon a number of factors such as chemical analysis, degree of restraint of the parts being joined, elevated temperature, mechanical properties, and material thicknesses.
When welding two different material groups, the minimum preheat temperature required shall be the higher temperature for the material to be welded. For prequalified procedures, preheat applicable to the higher strength group, as per Note 1 of Table 3.1-AWS D1.1. Also, thickness referred to for the minimum preheat is the greater of the nominal thicknesses at the weld of the parts to be joined. AWS D1.1, Table 4.5: Decrease from preheat and interpass temperature above 25 F (15 C) [100 F (55 C) for GTAW] is essential variable.
