High-Frequency Longitudinal Welding Technology for Steel Pipes

The rapid transformation and development of high-frequency longitudinal welded steel pipes has become an advanced scientific technology and is increasingly refined. From the initial roll forming to the later pass roll forming, and then to flexible forming, straight-edge forming, and combinations with other rigid frames, intelligent forming has already been achieved to a certain extent. In addition to welding and power supply technologies in the steel pipe welding process, it has now evolved into a fully solid-state system starting from the pipe forming stage, significantly increasing the thermal energy output compared to the original setup.

Researchers have been dedicated to addressing existing issues in high-frequency welding technology, proposing practical solutions to improve and correct the problems. By focusing on strengthening the welding zone, they have developed new welding technologies and quality control methods, significantly reducing the risk of incomplete welds, and achieving welding performance that is very close to the base material. This improves overall product performance and quality, and it is widely used in critical applications such as oil well pipes.
