Development of Self-shielded Flux Cored Wire and Its Application in Welding of High Strength Pipe Wire Steel

Abstract: Choosing the right welding process and welding materials is critical to the success of a project. Smart choices are often based on a clear understanding of the key characteristics and benefits of each option. This paper reviews the main features of the self-shielded flux-cored welding process in terms of productivity and performance. The 47-year history of the process is reviewed in terms of design and development, and the development of the process in the process and welding consumables is detailed.

I. Overview

Due to the uniqueness and advantages of self-protecting flux cored wire welding process, it has become more and more widely used in welding steel structure, infrastructure construction, offshore platform engineering and pipeline construction industries. These industries make full use of the self-shielding welding process to obtain high quality welds without the need for shielding gas, combined with the superiority of high productivity.........
