ABSTRACT:
A process for spot-welding hydroformed members allows at least one hydroformed member to be positioned with an end butted against a lateral side of the second hydroformed member. A structural shell member sandwiches the joint around the two hydroformed members to provide a surface to which each of the hydroformed members can be spot-welded. The U-shaped structural support receives the lateral side of one hydroformed member in the bight portion thereof and has arms that are positioned against the perpendicularly positioned second hydroformed member. Each of the hydroformed members are formed with access openings therein to allow spot-welding electrodes to be positioned against an appropriate wall of the hydroformed member and the adjacent portion of the U-shaped structural shell member. The joint is rigidly formed by spot-welding each of the hydroformed members to the structural support. The process is particularly adapted for utilization in the manufacture of automotive frames.
