The welding method of thick-walled steel pipe should be selected according to the material and wall thickness of the thick-walled steel pipe. Because different welding methods have different arc heat and arc force, they also have different characteristics.
The characteristics of tungsten arc welding are small current density, stable arc combustion, good weld formation, especially suitable for thin plate welding, but thick plate welding will not be selected;
The characteristics of the plasma arc are high arc column temperature, large energy density, good straightness of the plasma arc, its rigidity and flexibility have a wide adjustment range, and the work is stable, but the operation is more complicated;
Submerged arc welding has the characteristics of deep penetration and high wire deposition rate, so the welding speed can be greatly improved, the welding cost is lower, but the labor conditions and environment are relatively poor.
It can be seen that different welding methods have different capabilities and different operating costs. According to the material and wall thickness of thick-walled steel pipes, a reasonable choice of welding method is a very important task to ensure welding quality, increase productivity, and reduce costs.You can obtain more information and introduction about the product by logging on www.rd-steel.com
