Abstract
Based on the good mechanical properties,anti-rust performance and lightweight,aluminum al-loy was widely used in aviation,aerospace and other fields.Owing to its unique physical and chemical properties,the weldability of aluminum alloy is poor,and there are several welding defects generated dur-ing the welding process,such as blowholes,cracks,inclusion of slag and so on.The reason of aluminum al-loy (2A14)welding crack and the characteristics of repair welding process were studied;the matters nee-ding attention of aluminum alloy welding crack and the technology of repair welding have been discussed and explored in detail.At the same time,the welding process of repairing that was strict and detailed has been formulated;the repair welding of the flange was successfully completed.关键词
