High Frequency Welded Steel Pipe and Straight Arc Welded ...
High Frequency Welded Steel Pipe and Straight Arc Welded ...

Date: 2019-08-14 keywords: ,high frequency welded steel pipe,, straight arc ,welded, seam steel ,pipe, 1. ,High frequency, welding process of straight seam steel ,pipe,: according to the way in which the ,high frequency, current generates heat in the workpiece can be divided into ,high frequency, welding by contact and ,high frequency, welding inductively.

What is the difference between HFW and ERW?
What is the difference between HFW and ERW?

High,-,frequency, welding: ,high,-,frequency, current through the metal conductor, will produce two peculiar effects: skin effect and proximity effect, ,high frequency, welding is performed using these two effects of the ,welded, steel ,pipe,, these two effects is to realize a metal at ,high frequency, welding base.

Manufacturing control of high frequency welding pipe

High,-,frequency, power input to the steel ,pipe, weld part of the heat is called the input heat, the input heat is insufficient, the welding speed is too fast, the edge of the ,pipe, body can not reach the welding temperature, the formation of non-,welded, or not penetrated cracks but the input heat is too large , The welding speed is too slow, prone to over-burning, so that the breakdown of the weld ...

In High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.
