Welding technology of spiral pipe

The spiral pipe is a method of welding the arc under the flux layer, and the heat generated by the arc burning between the welding wire and the flux layer is formed by melting the welding flux and the base metal. This welding technology as long as the change in forming angle, you can use the same width of the strip to produce a variety of caliber steel pipe.

Double-sided spiral pipe welding technology has the advantage of its welding is continuous bending forming, so the length of steel pipe length is not limited; weld spiral evenly distributed throughout the steel pipe circumference, so the steel pipe size accuracy, strength High; easy to change the size, suitable for small batch, multi-species steel production.
