摘 要: | 为了保证钻机水龙头鹅颈管对接全熔透焊缝的焊接质量,提高一次探伤合格率,通过对焊接过程中的手法、技巧、焊接电流、电压、焊接速度以及主要操作流程等的反复实践,总结出了一套行之有效的单面焊双面成形焊接操作方法。采用此方法焊接的鹅颈管,经RT检测均未发现超标缺陷,焊缝内部质量和外观质量都达到了设计要求,成功地解决了鹅颈管焊接质量不稳定、一次探伤合格率低的问题,提高了生产效率,降低了生产成本。

Abstract: | In order to guarantee the welding quality of drilling machine gooseneck butt full penetration weld,increase the inspection qualified rate at a time, it summarized a set of effective one-side welding double-side forming method through repeated practice from some aspects during welding process,such as techniques, skills, welding current, voltage,welding speed and main operation process. After RT detection,it did not find the exceeding standard defects on gooseneck,which welded by using the above welding method. Both the internal quality and appearance quality of weld reached the design requirements,it successfully solved the problems of gooseneck,including unstable welding quality and low detection qualified rate at a time,increased production efficiency and reduced production cost. |
