AHSS steel welding with micro-jet cooling in mobile platforms

This paper focuses on the weldability of advanced high-strength steels (AHSS), commonly used by the automotive industry and civil engineering. These steels have found application in the construction of mobile platforms mounted on vehicles. AHSS significantly outperform other materials when it comes to performance flexibility and mass reduction potential. This article verifies whether the application of micro-jet cooling technology during the welding process might help to overcome these issues. The aim of this article is to choose welding parameters in the process with micro-jet cooling to obtain the best mechanical properties of the welded structure (elongation). The best welding parameters for these difficult-to-weld constructions are presented in detail.
