Friction Stir Lap Welding of Inconel 625 and a High Strength Steel …
A 3 mm thick Inconel 625 plate was friction stir-lap welded onto a marine-grade GL E36 steel substrate using FSLW. Table 1 presents the chemical composition of the Inconel 625 and GL E36 steel materials. Figure 1 a shows the lap joint configuration and the dimensions of both the steel and Inconel 625 plates.
