Research on the Process of Aluminium Alloy Short Cycle Dyawn Arc Stud Welding
Suitable welding process parameters are the necessary conditions for obtaining excellent welded joints in short-cycle drawn arc stud welding of aluminium alloy.The optimization of stud welding parameters for 6063-T6 aluminium alloy extruded profiles with thickness of 2.5 mm was studied.The influence of welding current,weld time and other parameters on the appearance,mechani-cal properties,metallographic structure and regional structure characteristics of welded joints was analyzed by controlling variables.Af-ter optimization,better welding parameters were obtained and the quality of the welded joint met the requirements of ISO 14555:2017.
