Abstract

To achieve metal constructions with high importance, it can be used different steels, but steel OL 52.4k has a very wide use due to technological properties and mechanical they present. Metallographic structure of materials of a welded joint is influenced by conditions that occur in the process of welding. In the researches there have been studied the influence of parameters of welding regime on the system of metallographic structure of materials from a welded joint in corner in “T” form. There was taken into account welding process MAG using three welding regimes and using steel plates from OL 52.4k steel with a thickness of 10 / mm.

Keywords

parameters of welding regime; metallographic structure; joint welded in corner in „T” form; welding process MAG
