The high-alkali flux with high melting point and fine particles is used in the multi-wire submerged arc welding of longitudinally welded pipes.

Is high frequency welded pipe the best way to weld steel high frequency electric welded steel pipe Submerged arc welding

The diameter of the high-frequency welded pipe is usually very small and does not need to pass through the welding wire, so the possibility of cracking during expansion is small. As far as the welding speed is concerned, the speed can be as high as 200 meters per minute for those with a smaller outer diameter, such as less than 1 inch.Introduction to Welded Pipe Manufacturing - The Process In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
