The welding deformation not only have bad effect on the good appearance, but also can result in all kinds of weld cracks.
銲接變形不但影響美觀，還可能會引發各種銲接裂紋。
Aluminium alloy's weld adapability is relatively bad, and easy to appear crack and air vent etc. in welding. The reasons are theoretically analyzed.
鋁郃金的可銲接性較差，熔銲時易産生裂紋和氣孔等缺陷，理論分析了缺陷産生的原因。
