What are the welding methods of geological steel pipes?
Manual welding: The length of the arc depends on the thickness of the gap between the electric welding electrode and the geological steel pipe, and it is adjusted by hand.
In order to make geological steel pipes more meet the construction requirements, we may need to weld the pipe fittings. Incorrect welding techniques can easily lead to false welding or inaccurate welding, which in turn will lead to the performance of the pipe fittings is degraded and the service life is reduced.It can be seen that it is necessary to master the correct welding method.Our commonly used welding methods are manual welding, metal pole gas shielded welding, inert gas shielded welding, argon arc welding, high frequency welding, etc. Xiaobian introduced these welding methods in detail.
1.Manual welding: The length of the arc depends on the thickness of the gap between the electric welding electrode and the geological steel pipe, and it is adjusted by hand. Moreover, when it becomes the arc carrier, the electric welding electrode is also a supplementary material for the weld. This is a widely used welding method.
2.Metal gas shielded welding: The arc is stable and heated under the shielding of the shielded gas, and the pipe fittings melt under their own arc.The welding method has good versatility, so it is widely used.
3.Inert gas shielded welding: An arc is generated between the refractory tungsten welding wire and the pipe fittings.
4.Argon arc welding: This welding method has good adaptability, high welding quality and good welding permeability, but the welding speed is not high.
5.High-frequency welding: it has a lower power supply, and can achieve a higher welding speed for steel pipes of different materials and outer diameter and wall thickness.
The welding methods of geological steel pipes mainly have the above points. Each welding method has its own unique characteristics, and the applicable fields are different. Therefore, we should choose the appropriate welding method according to the use environment and the nature of the pipe fittings.
