Abstract
In a process for separating overlapping sheet metal panels, which are welded together by a series of spot-welds, the portion of each spot-weld in one of the panels is removed by drilling or milling after which pressure is applied by means of a tool, driven by a pneumatic hammer device, to the remaining portion of the spot-weld in the other panel forcing the other panel away from the one panel and separating of the panels without substantial damage to the panels. Alternatively, a hole saw may be used to separate the spot-weld from the one panel before pressure is applied to the spot-weld to separate the panels.
