Ultra wear-resistant composite pipe What problems should be paid attention to during welding?
(1) Before welding the super wear-resistant composite pipe, check whether the power line of the welding machine is in good contact, whether the output plug is deformed, whether there is sediment or electric oxide layer, and eliminate various factors that may cause poor welding contact;
(2) When using the welding machine, we should pay attention to whether the welding machine is constant current welding or constant pressure welding. There is a big difference between the welding parameters of the two. It has been proved by long-term practice that our company generally adopts manual constant current welding, which not only has good welding effect, but also has relatively less time;
(3) When the welding machine uses the electricity generated by the generator, the output power of the generator should be greater than the output power of the welding machine. The welding personnel should pay attention to the change of the voltage on the welding machine display screen. When the voltage is not enough, the parameters on the welding machine cannot be adjusted. Even if it is adjusted, it will fall down. In this case, the output voltage of the generator needs to be adjusted to the voltage required by the welding machine;
(4) During the welding of super wear-resistant composite pipe, the welding personnel should pay attention to the changes of current, voltage and time on the display screen of the electric fusion welder to ensure that the welding process parameters of pipe fittings are met. The welding parameters of pipe fittings change slightly with the changes of climate and ambient temperature. The welding personnel should pay attention to adjusting the welding parameters
