In this paper, butt joint welds were conducted on mild steel SS400 and the aims of this research is developed a Plasma-GMAW hybrid welding process for single pass full penetration welding of 12-mm thick mild steel with no groove of thick steel plates. As a result, the single-sided welding in one pass with complete penetration was produced successfully and their mechanical properties were investigated. | Deep penetration welding of 12-mm thick section steels with no groove by Plasma-Gmaw hybrid welding process
