Abstract

The welding distortion of aluminum alloy end walls was taken as the example. The reasons of welding distortion of Al alloy end walls with plate-girder structure were analyzed and a suit of process program for producing end walls was summarized with preferable assembly sequence

high assembly quality

suitable welding procedure and prefabricated distortion to reduce welding distortion. By these means

the difficulty of repair and workload were reduced

the efficiency of production was increased

and high standard quality products were made.
