Pipe Manufacturing Process / Methods for Seamless & Welded ...

Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric Resistance Welding; EFW- Electric Fusion Welding; HFW- High-frequency welding; SAW- Submerged Arc Welding (Long seam & Spiral Seam)

Welding Principle of ERW Steel Pipe
Welding Principle of ERW Steel Pipe

The quality of high-frequency welding directly affects the overall strength, quality level and production speed of welded pipe products. Basic principles of high frequency welding. The so-called high frequency is relative to the frequency of the alternating current of 50Hz, and generally refers to the high frequency current of 50KHz~400KHz.
