Introduction to Welded Pipe Manufacturing - The Process Piping

The weld power is applied directly to the pipe, which makes this process more electrically efficient than high frequency induction welding. Because it is more efficient, it is well-suited to large diameter and high wall thickness pipe production.

Welded Pipe Manufacturing Processe - HardHat Engineer

In HFW welding, a high-frequency current is used to create weld joints. Whereas, in EFW welding process, the external high energy electric arc is used to create a weld joint. Once the welding is done, the excess weld material from outside and inside of the pipe is removed with the help of trimmer tools.

API 5L Welded Steel Pipe - Material - The Welding

Based on the welding frequency, the IF welding for low frequency and the ultra-IF welding for high frequency. In case of thin-walled pipe, there is a high frequency weld used typically in case of contact welding and induction welding. When the usage is for a small-diameter pipe, they make use of DC welding. There is a high frequency welding process used to manufacture pipes that are comprehensive and is of ERW type.

Pipe Manufacturing Process – Seamless and Welded Pipe

Welded Pipe Manufacturing Process. Once the circular section is rolled from the plate, the pipe can be welded with or without filler material. Welded pipe can be manufactured in large size without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow.

What is high frequency (HF) induction welding? - TWI

High frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape. The faying edges are brought together between squeeze rolls to produce a V at the point of welding, with an included angle of typically 2-5° for steel.

Production process of high frequency welded pipe

The production process of high frequency welded pipe depends on the type of product. It needs a series of processes from raw material to finished product. The completion of these processes requires a variety of mechanical equipment and welding, electrical control, and testing device.
