Abstract

A Study for the Weldability, Welding Position and Welded Joint Performance on the FCAW of HSA800 Steel HSA800;TMCP;FCAW;Weldability;Welding position;Welded joint performance;Homogeneity; In this research, 10 specimens of FCAW welding with positions of 1G and 3G were tested to confirm the weldability, welding positions, and welded joint performance of 60mm HSA800 steel. The test results showed that FCAW 1G and 3G satisfied HSA800 steel's KS and the criteria for homogeneity of strength, indicating a good weld zones. However, according to the tensile test results of weld zone, 3G position FCAW welding requires improvement of welding techniques and methods.
