摘要
分析了316L不锈钢分离器的焊接性和焊接工艺特点,根据其特点制定其焊接工艺:采用焊条电弧焊填充、盖面,采用氩弧焊打底,焊条电弧焊选用WSE-315型焊机、焊条A022,氩弧焊采用TIG400型号焊机、焊丝H00Cr19Ni12Mo2Cu2,采用V形坡口,坡口角度70°。焊后进行接头检验,结果表明,焊接接头成形良好,无咬边、凹陷、气孔、夹渣等缺陷;力学性能指标良好;焊道熔合较好,熔深满足要求。
Analysis of the welding of 316L stainless steel separator and its welding process characteristics,make according to the welding process and its characteristics：filling and covering by shielded metal arc, welding,argon arc welding with SMAW selection, type WSE-315 welding,A022 welding rod,argon arc welding using TIG400 type welding machine,welding wire of H00Cr19Ni12Mo2Cu2, using the V groove,groove angle 70°.For joint test results show that, after welding,forming a good weld joint,undercut,depression, porosity,slag and other defects;index of mechanical performance is good;the bead fusion penetration is better,to meet the requirements of.
