The common welded defects in the joints are oxide slag,porosity,cracks,etc. The occurrence of weld porosity and cracks could be reduced by removing the oxide film,dirt and oil completely before welding,strengthening the protection for welding pool,etc.
试验过程发现:AZ31镁合金TIG焊和等离子弧焊接时存在的主要缺陷都是气孔和热裂纹,对工件表面的氧化膜和油污进行处理,加强对焊接熔池的保护等工艺措施,可以有效减少焊接气孔和焊缝裂纹的产生。
