Spiral steel pipe manufacturers use welding rods and welding wire which is better

- Nov 12, 2020-

The welding before the spiral steel pipe manufacturers basically used the welding rod to complete the welding, but following the development of our era, the electrode was gradually replaced by double-sided submerged arc welding. Why is Xiaobian saying this? In fact, our previous application of manual welding and double-sided submerged arc welding are protected by slag, but we have developed flux by hand-welded slag. Here we talk about the technology and rise of double-sided submerged arc welding.


We all understand that manual welding needs to be stopped. For double-sided submerged arc welding, there is no need to stop. This method is completely automated, and the welding is performed under the submerged arc, so his heat exchange and protection. The quality is stronger than manual welding, and the quality of the welding is also relatively high. This is because the submerged arc welding is caused by the electric submerged arc under the flux, so he can also use large current and improve the welding efficiency. The welding process reduces manual waste.

Short DescriptionSpiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications.
