PURPOSE: A multi-functional large article welding device is provided to smoothly weld a welding member by moving the welding member back and forth to adhere to the surface of a workpiece, thereby maximizing the workability and a processing quality. CONSTITUTION: A multi-functional large article welding device includes a body (110), a lifting member (120), a fixing member (130), first and second moving members (140,160), a supporting member (150), an assisting member (170), and a submerged welding member (180), or welding member (200). The welding member is installed on a side of the assisting member to be moved back and forth. The second moving member is moved in left and right sides while the fixing member fixes one end portion of a workpiece so that the submerged welding member or the welding member performs a welding task on the surface of the workpiece. |
