Abstract
Deformations around the end of puddle during welding on 2mm thick aluminum alloy sheets were measured by a new contactless method, by means of film recording. Moreover, the accuracy of this measuring method was investigated. The effects of welding conditions, the rigidity of test pieces and the measuring location on test piece on the deformation characteristics which occurs in the transverse direction of welding seam near the end of puddle during welding were investigated. Their results were adopted to investigate initiating and propagating mechanism of solidification crack. Moreover using the measured deformation speed the reasonable specimen size and the shape were investigated for the solidification crack susceptibility test of thin sheet.
