In the actual work of the pipe jacking machine, the wear resistance of the cutter head and cutter head is very important. Some work in a sand layer of a gravel layer and find that the required alloy is missing, while the tool seat is relatively intact. This generally occurs, and its failure form is blockage and shedding, rather than wear. Therefore, when we choose wear-resistant flux-cored welding wire, we must consider the wear resistance of the wear-resistant layer during work, and also take into account the toughness and impact resistance of the wear-resistant layer during work. Taking both into consideration can make the workpiece last longer during use.
Generally, for the wear-resistant layer of the pipe jacking machine, we use the TM582 flux-cored welding wire of TecMig. This welding wire has both wear resistance and toughness.
