铝合金MIG焊常见焊接缺陷分析及预防措施
Reason analysis and precautionary measure on MIG weld defect of Aluminium alloy
摘要
Abstract
It is easily to cause weld defects in the aluminium alloy welding process because of its nature.The weld defects including pores,cracks, fusion defects,etc.Weld defect will affect quality of products. While welding as one general connection method in the railway vehicle production, the weld joint is the weak and easy to destroyed part in aluminium alloy structure.So assurance the weld joint quality is one of key measure to ensure the safety of railway vehicle working.MIG welding is the main weld method in railway vehicle production by now.It will be introduced about reason analysis,damage,prevention measure and solving measures of the weld defects in this test according the production process.关键词
