Abstract

Purpose: The aim of the article was to obtain high-quality connectors for the automotive industry and antenna structures. Design/methodology/approach: For the welding joint the duplex steel and parameters of TIG welding process were chosen. The mechanical properties of the joint were carefully checked. Findings: Relations between process parameters and the quality of welds. Research limitations/implications: In the future, it can be suggested to investigate the effect of micro addition of nitrogen in gaseous shielding mixtures of the welding process. Practical implications: The development allows to obtain high-quality welded joints made of duplex steel. The solution can be implemented in the automotive industry or for the production of antenna structures. Social implications: Modifying the welding method will not affect the environment and production management methods. Originality/value: The article is addressed to manufacturers of stainless steel for automotive industry and to manufacturers of antenna instrumentation. Keywords: welding, 1.4462, duplex, automotive, antenna. Category of the paper: Research or technical papers.
