PURPOSE:To perform unmanned welding, by providing an arc length controller and a torch adjusting mechanism controller, and determining a torch aim position in a weld-layer direction and a weld-bead width direction. CONSTITUTION:The titled welder is equipped with the arc length controller 13 which adjusts the aim position of the weld layer direction each weld bead layer and the torch adjusting mechanism controller 16 which makes a breadthwise aim position adjustment and performs continuous multilayer welding. The said controller 13 detects an arc current generated between a base metal and an electrode to adjust arc length l to a set value and holds it, and also adjusts the aim position of the torch in the weld bead layer direction to prescribed positions S1 and S2 of respective layers. The said controller 16 has a setting part for setting the position order of the aim position of the torch in the weld bead width direction and moves and adjusts the welding torch 2 to the breadthwise torch aim position of the prescribed bead of each layer. |
