一、问题的提出我单位加工制造的某一种储箱,按使用要求结构材料选用LF_3铝合金。整个储箱由园筒、箱底和隔板等另件经滚焊而成。滚焊前要对所有的另件表面进行酸洗或碱洗处理,清除另件表面Al_2O_3膜和油污,尽量减小另件的接触电阻,保证焊接质量。滚焊的工作情况如图1。 First, the question put forward I process a certain kind of tank manufactured by the use of structural materials selected LF_3 aluminum alloy. The entire tank from the cylinder, box bottom and other pieces by the Barrel welding. Before the welding, all the other parts should be pickled or alkali-washed to remove the Al 2 O 3 film and oil from the other parts, minimize the contact resistance of other parts and ensure the welding quality. Rolling the work shown in Figure 1.
