How to ensure quality of high frequency welded pipe in

How does high frequency induction welding work?How does high frequency induction welding work?There are two types of High Frequency ERW processes. In High Frequency Induction Welding, the weld current is transmitted to the material through a work coil in front of the weld point. The work coil does not contact the pipe. The electrical current is induced into the pipe material through magnetic fields that surround the pipe.Introduction to Welded Pipe Manufacturing (pipe) Why do HFW steel pipes have a high welding speed?Why do HFW steel pipes have a high welding speed?Since the speed is very high, the contacted plate edge could be heated and melted in shore time, then extruded through docking process. and In the welding process, HFW steel pipes do not need to add filling meta. So it has fast welding speed and high efficiency in production.Differences between ERW Steel Pipe and HFW Steel Pipe(pipe) How to Guarantee the Product Quality of ERW High

Smooth appearance, high precision, low cost and small weld reinforcement, which is beneficial to the coating of 3PE anticorrosive coating. The welding methods of high frequency welded steel pipe and submerged arc welded pipe are significantly different. Since welding is completed instantly at high speed, it is much more difficult to ensure welding quality than submerged arc welding.

People also askWhat do you mean by high frequency welding?What do you mean by high frequency welding?High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.Differences between ERW Steel Pipe and HFW Steel Pipe(pipe) Process Flow and Precautions of High Frequency Welded

1. The influence of raw materials on the welding quality of steel pipes. The main factors affecting the quality of raw materials are the unstable mechanical properties of the steel strip, the surface defects of the steel strip and the large deviation of geometric dimensions. 2. In the production process of high-frequency welded pipes, how to ensure that the product quality meets the requirements of (pipe) Production process of high frequency welded pipe(steel) 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.
