| Abstract | This work aimed to evaluate the welding quality and the sustainability of an automatic metal active gas with mixinggases (MAG-M) process for welding the valve boss on liquefied petroleum gas (LPG) upper cylinder half, in comparison to thepresently used automatic submerged arc welding (SAW) process. The weld quality of MAG-M welding samples met the ASMEstandards, comparably to the SAW welding samples. In addition, the MAG-M welding process for welding LPG valve bosses ispreferable over the SAW welding process on the condition that >73,339 pieces are processed. However, the welding fumes andnoises from this process have stronger environmental and social effects than those from SAW welding. Besides, the SAWprocess is preferable in LPG valve boss production up to 73,339 pieces. The solid waste or slag generated in this welding processshould be managed. |
