Effect of the Rolling Direction to the Ultimate Tensile Strength of Butt Welds for ASTM A36 Steel

The objective of the paper is to give different results on the ultimate tensile strength (UTS) of the weld with samples cut from three different positions on the ASTM A36 steel plate. Specifically, every two samples are cut respectively in the rolling direction (RD), perpendicular to the RD, and 45 degrees to the RD. Three butt welds are made using the flux-cored arc welding (FCAW) technology. The results show that the UTS of R1-R2 weld is higher than C1-C2 and T1-T2 welds.
