本文提供了一种无需切断焊缝返修处的塔器和管道即可对内表面无衬垫的管道进行返修焊接,返修质量好,作业过程省时省力的铝镁合金管道焊缝返修方法,解决了现有技术中存在的铝镁合金管道焊缝返修时需要割断返修部位的管道,甚至增加辅助接口,从而导致焊接作业量增加,浪费人力物力等的技术问题。 This article provides a method for rework welding of aluminum-magnesium alloy pipelines without reworking the inner surface of the pipe without reworking the tower and piping at the weld repair, repairing the welds with good quality, and saving time and labor during the operation. In the prior art, when the weld of the aluminum-magnesium alloy pipe is repaired, the pipe of the repaired part needs to be cut off, and even the auxiliary interface is added, which leads to the increase of welding work load and the waste of manpower and material resources.
