摘要
Abstract
The influence of welding process parameters on weld forming are analyzed by experiment on welding process of 16 mm thickness 5083 aluminum-alloy of VPPAW (variable polarity plasma arc welding) welding.Welding procedure for the aluminum-alloy tank without groove of VPPAW welding in argon shielded preheated before or helium argon mixture gas shielded was studied and the specific welding process specification was established.The results show that some defects can be avoided effectively such as uneven preheating of long weld and local undercut at the back of weld in the workpiece welded in helium argon mixture gas shielded.In addition,this welding process can decrease heat input and improve welding efficiency, the weld both face and back sides are defect-free in visul test and the weld quality attains radiographic test 1 level.lt is satisfied to the design requirements of high voltage switchgear equipment.关键词
