处理无锡焊管内焊撕裂的小技巧

文章出处:作者:人气:2发表时间:2018/6/29 15:24:10【

  无锡焊管是焊缝与钢管纵向平行的焊管,生产工艺简单,生产效率高,成本低,发展较快,一般情况下,自由边的曲率都比较理想,递送边则不同,由于受客观条件的限制,递送边变形不如自由边变形充分,直缝钢管生产厂家当变形不足达到一定程度时,递送边向外翘曲的力致使内焊撕裂。

  无锡焊管幸运飞艇不倍投计划出现这种情况的原因在于成型缝间隙变化过大、带钢边缘有小毛刺或小缺口、成型错边,焊丝直径不均匀、焊丝接头不光滑、焊丝硬度不均匀造成送丝不均匀、金属毛刺导致的电嘴处瞬间短路。出现这种情况,不必进行大的调整,可以在条件允许的情况下尽可能将带钢边缘处理光滑并保持成型稳定。
