ABSTRACT:
Welding jig apparatus for holding bar stock workpieces in an intersecting and aligned relationship to form a metal grating structure includes a number of elongated radial cams located in a spaced apart relationship to each other and in two parallel rows on a work surface. Workpieces are located between adjacent cam faces of cams opposite one another in the two rows when the cams are in a nonclamping position. The workpieces are clamped into the desired position by arcuate cam surfaces when the cams are rotated to clamping position. The work surface is tiltable to one of a number of work positions to facilitate the welding of intersecting workpieces into the grating structure.
