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.
A jig for welding sheet metal workpieces to define a box-like structure having opposed pairs of wall panels and an end panel and lines of juncture therebetween comprising, base means, frame means on said base means and including frame members extending in the direction of said lines of juncture, wall means cooperable with said frame means to receive and releaseably support said work pieces therebetween, said frame members having gas passageway means therein connectable to a source of inert gas and including outlet means for delivering inert gas in the direction of said lines of juncture, said wall means including a fixed wall on said base means having an edge corresponding to one of said lines of juncture and said frame members including a first frame member generally parallel to said edge and movable relative to said fixed wall, means supporting said first frame member on said base means for reciprocating movement between first and second positions along a path toward and away from said wall edge, and means to selectively reciprocate said first frame member between said positions, said first frame member being adjacent said fixed wall when said first frame member is in said first position.
A jig for welding C-shaped and L-shaped sheet metal blanks together to define a box-like structure comprising, base means having opposite ends and opposite sides, frame means on said base means, said frame means including upright frame members adjacent said sides at one of said ends and side frame members spaced above said base means and parallel to a corresponding one of said opposite sides, said frame means further including an end frame member at the other of said ends of said base means, and wall means on said base means, said wall means including end wall members at each of said opposite ends of said base means and sidewall members at each of said opposite sides of said base means, each of said side wall members and at least one of said end wall members being supported on said base means for movement between first and second positions relative to said frame means, said side and one end wall members in said first positions being cooperable with said frame means to support said blanks with adjacent edges thereof defining lines of juncture therebetween for welding, said side and one end wall members in said second positions thereof being displaced from said frame means for said blanks to be received and removed from said frame means, said upright, side and end frame members including gas passageway means connectable to a source of inert gas and having outlet means for directing inert gas between said adjacent edges of said blanks along the lines of juncture therebetween.
