在石油化工装置检修及工艺管线焊接施工中，焊条离焊接坡口一定距离就会被强力吸附到管道上，焊接时焊条引弧后产生的反向电流磁场与剩磁磁场相互作用使电弧向坡口外偏吹，无法形成熔池和焊缝，使带磁状态下不能实施管道焊接。In the maintenance of petrochemical equipment and the welding construction of process pipelines, the electrode will be strongly adsorbed to the pipe when it is a certain distance away from the welding groove. Blowing outside the mouth makes it impossible to form molten pool and weld seam, so that pipeline welding cannot be carried out in the magnetic state.
目前对于压力管道的坡口区进行焊接前，由于坡口区的磁性超标，进而导致无法对压力管道的坡口区进行焊接，需要人工对压力管道的坡口区进行消磁处理，不仅降低了对压力管道的焊接效率，同时还延长了对压力管道的焊接施工工期。At present, before the welding of the bevel area of the pressure pipe, because the magnetic properties of the bevel area exceed the standard, it is impossible to weld the bevel area of the pressure pipe. It is necessary to manually demagnetize the bevel area of the pressure pipe, which not only reduces the The welding efficiency of the pressure pipeline is improved, and the welding construction period of the pressure pipeline is also extended.

The continuous grounding method is used to increase the temperature of the welding zone and slow down The temperature of the heating zone decreases quickly. When the heating zone changes from bright red to dark red, the welding sound changes, and the deposited metal in the molten pool cannot be fused. Stop welding immediately and reheat.
根据钢管直径加热焊接6-12处，由原来磁性最强的两端转变为连接后的中段，磁性得到弱化，剩余磁性经6-12段的打底焊接处通过，未打底处的磁性可以达到标准小于0.3mT(240A/m）的要求，可以正常焊接。According to the diameter of the steel pipe, it is heated and welded at 6-12 places, and the two ends with the strongest magnetism are transformed into the middle section after the connection. The magnetism is weakened, and the residual magnetism passes through the bottom welding part of the 6-12 section. It meets the standard requirement of less than 0.3mT (240A/m), and can be welded normally.
对于要求较高，有相应无损检测要求的焊缝，可以双面焊的，在完成外圈的焊接后，到管内清除打底层，再进行封底焊，对于只能单面焊的，完成6-12段打底后，根据焊接情况进行处理，其他处能正常焊接的，先进行其他处的打底、填充、盖面焊接，然后再将6-12处的打底处逐一清除后重新进行打底、填充、盖面的焊接；如磁性仍较强，其他处仍无法正常的焊接的应先将6-12的打底处，进行填充或填充+盖面的焊接，也增加磁通量，使其他处能够正常焊接，待其他处正常焊接完成后，再将6-12处的焊缝逐一重新焊接。For welding seams with high requirements and corresponding non-destructive testing requirements, double-sided welding can be performed. After the outer ring is welded, the bottom layer should be removed in the pipe, and then the bottom sealing welding should be performed.
