| Abstract: | The 2 m long and 50 mm thick plate was welded by the double-sided arc welding process. The welding productivity of the thick plate by double-sided arc welding process was 1. 4 times more than that of the troditional single MAG arc welding, and the mechanical properties of welded joint could meet the requirements. The metallurgical structures in the HAZ by double-sided TIG arc backing welding were the lath martensite, and those in the welding seam were composed of the acicular ferrite and the lath martensite. |
