In GMAW welding used mostly at the scene of a welding industry, welders can not see controlpanels in internal welds of vehicles and tanks, and can not adjust the current and voltage properlyduring the welding, which is caused by distance from the working area. Therefore, welders have tomove to control the current and voltage by stopping welding. This, however, can result in the weldingdefects by momentary cooling. In this research related to the existing GMAW welding methods and themanners with the remote control torch their performances were evaluated by comparing and analyzingthe welds of V-type butt using SM50A 6 mm and welding structural rolled steels. As the result ofconducting the visual inspection and bending test one by one against the V-type butt welds, the amountof spatter by the remote control torch method showed reducing effects about five times lower and it hada performance that did not affect the weld defects by displaying suitable effects on the bending test ofwelds. Consequently, the experimental study on the possibility of replacement and compatibility with theexisting commercial welder for the remote control torch was performed.
