Claims

[Claims for Utility Model Registration] 1. A device for replacing a welding back bar having a stop that comes into contact with the outer surface of a welding part of a workpiece, which includes a pair of circulatingly driven chains installed in parallel, and a chain between the two chains. A plurality of back bars are installed horizontally at intervals in the circulation direction, and any one of these back bars can be freely selected to a predetermined operating position by circulating the two chains, and the back bars can be indexed to the operating position. 1. A welding back bar changing device comprising a locking member that engages with the back bar to lock the back bar in an operating position. 2. Claim 1 characterized in that a spatter cover is provided between the two chains to prevent spatter from scattering to the back bar located at a position other than the operating position, and is foldable inward of the movement locus of the back bar.
The welding back bar replacement device described in .
