Table 5.

Tensile properties of the base metal (BM), girth weld (GW), seam weld (SW), girth weld HAZ (GH), and seam weld HAZ (SH) acquired in air at room temperature [YS = yield strength, YP = upper yield point, UTS = ultimate tensile strength, e_u = uniform elongation, e_f = elongation to failure, and E = elastic modulus].
