The forming characteristics of electric resistance welding (ERW) tube manufacturing processes have been analyzed in detail. Two typical ERW tube forming processes with and without cage forming section are compared to make high-strength steel tube and pipe for various applications. The technical challenges during tube forming are presented, such as eliminating the strip edge buckles when making thin wall tube and reducing the flat spot on the tube surface for improving tube quality. The mill setup and optimizing tooling design, as well as key parameters to check at the mill, are proposed. This paper describes the fundamental tube deformation, which is essential to clearly understand the forming process for achieving better performance of ERW tube mills.
