FABRICATION AND TENSILE TESTING OF LAPPED WELDED AL PLATE

Abstract

This study was aimed at establishment of a model that can predict tensile strength of gas welded lap
joints. In present study six samples of the aluminum are produced by varying their overlap length. These
three plates are fabricated by gas welding technique. To know the tensile strength of the lapped joints, these
plates are tested on universal testing machine. It is found that more the overlap length more the strength of
the weld.Finally, estimation of the tensile strength and the fracture portion of the joints were achieved. This
estimation made good accordance with the experimental results.
