Seamless Steel Pipe Weld Treatment
Seamless steel pipes have no obvious welds during the manufacturing process because they are formed by overall heating and rolling. However, weld seam preparation is usually a step in the production of steel pipes related to welding, especially for steel pipes made by welding, such as long welded seam steel pipes. The following are some steps and methods for welding seams.

Repair of S355 LSAW Steel Pipe Transverse Crack
With the development of the national economy, thick-walled LSAW steel pipes are increasingly used in offshore platforms, high-temperature and high-pressure vessels, wind power pipe piles and other fields. The production of such steel pipes generally uses D36 steel, S355 steel and structural steel plates with Z-direction properties. The plate thickness is large, the carbon content is high, and the carbon equivalent is high. The weldability is poor and the hardenability tends to increase. The welding performance of the joint is reduced and cold cracks are prone to occur, especially transverse cracks. This article will take S355 LSAW steel pipe as an example to explain how to repair transverse cracks. Continue reading to learn more.
