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.
