A welding jig is provided for supporting C-shaped and L-shaped sheet metal blanks during welding thereof to form a dishwasher housing. The welding jig includes a frame against which the panels of the blanks are disposed with adjacent edges in positions to be welded, and the blank panels are held against the frame by corresponding wall plates during the welding operation. Certain members of the frame are disposed along the lines of juncture between the blanks and are provided with passageways for delivering inert gas to the line of juncture between the blanks during the welding operation. One of the frame members is displaceable relative to a fixed wall of the jig to facilitate the introduction and removal of the blanks, and the remaining walls of the jig are movable relative to the frame for the latter purpose.
