OUT-OF-PLANE DISTORTION CAUSED BY FILLET WELDS IN ALUMINUM

Out-of-plane distortion caused by angular changes at fillet welds on aluminum structural panels was analysed in two steps, namely, the experimental and the analytical. In the experimental step, a series of data were obtained from test specimens with varying thicknesses, which were fillet welded to either a single frame or to three equally spaced frames. The results of the tests were analysed and were then compared with those available for steel panels. It was found that although the distortions of the aluminum panels were larger when the same amount of consumed weld metal is considered, the steel panels have shown larger distortion if the same fillet size is taken as a parameter. In the second step, this behavior of the aluminum was studied and an analytical investigation concerning the free joint angular distortion was developed, assuming that the distortion will be caused by a point heat source moving in a straight line. The theoretical analysis was based on the incremental strain method theory and the thermal, elastic-plastic angular deformations were estimated for the aluminum and steel panels for the simpler case of the free-joints, because the free-joint angular distortion is directly related to the distortion of the contrained joint panels.
