Welding assembly of a large sized shipping container made of aluminum alloy

This paper focused on the welding construction process for a large sized shipping container about 7 m in length, which is a whole welding assembly made of aluminum alloy 5A06-H112 with 5 mm in thickness. The process investigation covers specialties of welding material selection, pre-welding preparations, tack welding assembly, welding parameters' regulation, welding sequence control and deformation control, followed by post-welding inspections and welding defect repair. The results show that the designed process can meet the specifications of the container's welding assembly.
