Paper Abstract

Although welding experiments on light alloys (aluminium or titanium based) have been performed since the beginning of the 1980's, the relative techniques have rarely been applied to production. The major difficulties in laser welding these alloys is only partially due to the differing thermal properties of the materials: another feature of light metals is the high reflectivity to laser radiation of aluminum and the extreme intensity of the plasma generated by laser on titanium. Welding tests were carried out on light alloys under abnormal conditions (controlled atmosphere, special nozzles, non-traditional covering), with various working parameters, have been analysed by means of fractography, Auger spectroscopy, X-rays and electronic and optical microscopes, to check that the quality control specifications of the aerospace industry have been fulfilled.
