ABSTRACT:
An improved pressure welding technique permits high speed room temperature seam bonding of metal sheets. A metal interlay is placed between the faying surfaces to be bonded and the assembly is compressed until the interlay is properly spread over the faying surfaces. The interlay has a cross-section designed to produce a highly differential flow when subjected to external compressive loads. This differential flow causes shear movement between the interlay and the faying surfaces which effects the weld. Joining speeds in excess of 10 feet per second are possible, with a reduction in sheet thickness of about 5 percent.
