How are welded tubes primarily formed?

Welded tubes are primarily formed by rolling flat strips of metal into a tubular shape. This process involves taking a flat sheet or strip of metal and rolling it to create a cylindrical shape. Once the edges of the strip meet, they are welded together, typically using methods such as high-frequency electric resistance welding or multi-pass welding techniques. This production method is efficient and allows for the creation of tubes of various diameters and wall thicknesses, depending on the specifications required for their intended application.

This process is commonly used in the manufacturing of various types of welded tubes, including those for structural applications, automotive components, and more. It is favored for its versatility and ability to produce long lengths of tube with consistent quality. The use of flat strips also allows for better control over the material properties and dimensions of the final product.
