Abstract针对新型铜/不锈钢单缝直焊型电解铜永久阴极板焊接接头的特殊要求,采用S201,S231和CuNi-7三种不同Ni含量的焊丝对T2紫铜与316L不锈钢进行GTAW焊,并对接头微观组织、成分、电导率和耐腐蚀性进行了分析.结果表明,三种不同Ni含量的焊丝所得焊缝界面清晰、无明显的宏观焊缝缺陷,但Ni含量的增加会对焊缝表面成形有一定影响;Ni含量低时会使钢侧焊缝中产生少量微裂纹,而随着Ni含量的增加焊缝中条状和块状 Ni-Cr-Fe相随之增加;随着焊缝中Ni含量的增加,铜/不锈钢接头的电导率有所下降,这与焊缝中存在的Ni-Cr-Fe相数量成反比;铜/钢接头中Ni含量的增加可较为明显地提高铜/钢接头在酸性条件下的耐腐蚀性能.
