These advantages of the export welding process of spiral steel pipes have directly established its market position These advantages of the export welding process of spiral steel pipes have directly established its market position 1.High production efficiency On the one hand, the conductive length of the welding wire is shortened, and the current and current density are increased, so the penetration depth of the arc and the welding efficiency of the wire are greatly improved. (Generally, the single-side melting depth can reach 20mm without opening the groove.) On the other hand, due to the heat insulation effect of the flux and slag, there is basically no heat radiation on the arc, and there is little spatter. Increased, but the overall thermal efficiency is still greatly increased. 2.High weld quality The slag has a good protection effect from the air. The welding parameters can be kept stable through automatic adjustment. The technical level of the welder is not high. The weld composition is stable and the mechanical properties are relatively good. 3. Good working conditions In addition to reducing the labor intensity of manual welding operations, it has no arc radiation, which is a unique advantage of submerged arc welding. The export spiral steel pipe is suitable for oil, gas and water pipelines, tap water, gas, pipelines, oil refineries, chemical plants, sewage treatment plants. It is believed that more and more people will choose spiral steel pipes, and the development of the industry will become more and more promising. Post time: Jan-10-2020
