영문 초록

It is well known that solidification cracking often occurs in welds of root pass for one-side welding under the conditions of high welding currents and speeds. In this study, the solidification cracking in SPPV490 was investigated by using FCAW with 4 types of welding wires and welding conditions of 200～280A and 2.8～ 4.2mm/sec. In order to compare the result of cracking in SPPV490, the experiments were also conducted with SWS400 and SM45C as base compared metals. As the results, all the cracks formed in some welding conditions were observed near the center of weld bead. The cracking tendency with bead was extended under the condition of higher welding currents.
