【摘要】 对表面阳极化铝型材分别在不同母材表面预处理和采用不同填充材料情况下的焊接工艺进行了试验研究。结果表明 ,采用钨极氩弧焊方法 ,在两种预处理条件下 ,用 Al- Si焊丝施焊获得的接头组织致密 ,未发现有气孔、夹杂和微裂纹等缺陷 ,接头性能明显优于用纯 Al焊丝获得的接头更多还原

【Abstract】 Under the condition of different pretreatment technology and by using different filler materials,the welding technology of anodizing shaped aluminium alloy was investigated.The results show that the joint structure with Al-Si filler material is dense,no gas holes,no inclusions nor microcracking can be found,and the joint properties with Al-Si is obviously better than that of with pure Al by means of tungsten inert gas arc welding.更多还原
