野外管道施工在连片水田、沼泽水网、深丘、山区等特殊地形,大型设备难以进入作业现场,而且大功率电站发电需架设低压输屯线路,其成本高,搬迁困难,架设低压线投入大,且不安全。在管道连头、焊缝返修作业中使用大型设备不合理且费用高。在这些特殊地形、特殊作业中选择移动方便、灵活、轻型自发电手工电弧焊机(AXQ1-300X)及自发电半自动焊机(APQ1-300F或APQ1-300K)将是明智之举。焊接作业中,合理组合作业机组以满足工艺要求,实现优质、高效的焊接是非常重要的。在上述特殊地
Field pipeline construction in contiguous paddy fields, marsh water network, deep mound, mountainous and other special terrain, large-scale equipment difficult to enter the job site, and high-power power plant need to set up low-pressure transmission lines, the high cost, relocation difficulties, set up low-voltage line input Big and insecure. It is not reasonable and expensive to use large equipment in pipe fittings and weld repairs. In these special terrain, special operations easy to move, flexible, light self-powered manual arc welding machine (AXQ1-300X) and self-powered semi-automatic welding machine (APQ1-300F or APQ1-300K) would be wise. Welding operations, the reasonable combination of operating units to meet the technical requirements, to achieve high quality and efficient welding is very important. In the above special
