Joining and Testing Bimetallic Automotive Panels

Reflecting the need for field testing of bimetallic automotive body sheet; an extensive program was planned in 1974. Adhesive bonded and weld bonded panels (2036 aluminum and 5182 aluminum with 1010 steel) were prepared and exposed at atmospheric test sites at Pompano Beach, Florida; Phoenix, Arizona; Chicago, Illinois; and Richmond, Virginia.

Exposures were made in 1975-76 and 1- and 2-yr removals and evaluations are reported in this paper.

“In-plant” and “After-market” repaired aluminum panels were exposed at the same time. These results are reported here.
