Abstract | The invention discloses a welding method of a pipeline weld joint hidden part. The welding method comprises the following steps that an opening of a concrete trench is projected by taking a leakage point as a center to form a projection path; a plurality of through holes are cut in the pipeline through which the projection path passes; the leakage point is welded through the through holes; and thethrough holes are sequentially spliced and welded from inside to outside. According to the welding method of the pipeline weld joint hidden part, the hidden part of the pipeline weld joint can be welded under the condition that the pipeline is not disassembled, the pipeline with the leakage point does not need to be jacked up, the welding maintenance cost is reduced, the welding efficiency is improved, the operation is simple and easy to implement, and the requirements for technicians are reduced.
本发明公开了一种管道焊缝隐蔽部位焊接方法,包括:以漏点为中心向混凝土地沟的开口处进行投射,形成投射路径;在投射路径经过的管道切割出若干通孔;穿过通孔对漏点进行焊接;由里至外依次对通孔进行拼装焊接。使用本发明提供的管道焊缝隐蔽部位焊接方法,可以 |
