In the 15CrMo steel pipe welding process, the short arc welding method is adopted to replace the electrode quickly and agile, to reduce the number of arc lifting and arc extinguishing as far as possible, to prevent air from entering the gas hole produced in the molten pool, and to grind the arc place carefully.
The middle layer 15CrMo steel pipe welding wave is wider, generally using the saw-shaped transport strip method for continuous arc welding. When the 15CrMo steel pipe cover surface is welded, the crescent movement bar method can be used, the swing is a little slow and steady, so that the welding wave is uniform and beautiful in the 15CrMo steel pipe.
The weld of 15CrMo steel pipe should be welded at once. If you are forced to interrupt for some reason, you must take measures to prevent cracks in accordance with the requirements of the process. Only after the 15CrMo steel pipe welding process is preheated before welding can the welding continue.
