The water pipe network system is an infrastructure of industrial enterprises, and is used for conveying and circulating tap water, fire water, cooling (freezing) water, sewage and the like. In the actual production process, the pipeline is often required to be installed or modified, and welding is inevitably carried out on the pipeline. In the electric arc welding, a grounding loop is connected with a weldment through a grounding clamp, the other end of the grounding loop is connected with a welding holder, then a welding rod on the welding clamp generates strong electric arc due to short circuit when contacting with the weldment, an arc pit is burnt on the weldment, metal on the welding rod is flatly laid in the arc pit, and a welding seam is generated in the process of continuous movement of the arc pit. Due to the fact that the pipe diameters of a plurality of pipelines are large, and the opening degree of the grounding clamp of the electric welding machine is limited, the pipelines cannot be conveniently and stably clamped near a welding seam, and the quality and the efficiency of welding operation are affected. The bottom line clamp can not be clamped at a position far away from quilting, because the electric conductivity of a weldment is not as good as that of a cable, the clamping distance is long, the welding current is insufficient or unstable, even if the welding can be stably carried out, the welding current is larger than that required to be adjusted at the nearest position in an overlapping mode, the load of a welding machine is increased, and electric energy is wasted. In order to meet the welding requirements, a method often adopted by an electric welder is to weld a temporary angle iron on an official channel and clamp a ground wire on the angle iron, so that the operation is inconvenient and unsafe, and certain damage can be caused to the channel.
