摘要:
螺旋埋弧焊管焊接质量与成型合缝质量密不可分,成型合缝控制不好会产生气孔、夹渣、焊偏等焊接缺陷。简要介绍了螺旋埋弧焊管成型工艺及理想的成型合缝的条件。结合生产工艺,分析了间隙异常、错位和非对称3种异常合缝产生的原因、对焊接过程的影响以及异常合缝的形成过程及分布特点,并结合生产经验给出了相应的控制预防措施。在焊管生产过程中,应严格控制每一道工序,确保成型合缝均匀、稳定,为焊接提供良好的工艺条件。
Abstract:
The welding quality of SAWH pipe and the quality of forming joint close are inseparable,poor forming joint close will cause some welding defects,such as gas pocket,slag inclusion,deviation etc. In this article,it briefly introduced SAWH pipe forming process and ideal forming joint close conditions. Combined with process,it analyzed forming reason,the effect on welding procedure,forming process and distribution characteristics of 3 kinds of abnormal forming joint close,including abnormal gap,dislocation and asymmetry. It also gave corresponding control and prevention measures. During production course,it should strictly control each working procedure to ensure uniform and stable forming joint close,and provide good process conditions for welding.
