Properties analysis of Homogeneous Welding joints of the Duplex – Austenitic Steel type Welded with Austenitic Wire

The article presents the structure and properties of dissimilar welded joints based on duplex 2205 and austenitic 316L stainless steels manufactured using Avesta P5 austenitic binder. The purpose of researches was to analyze the impact of joint type and binder material on the mechanical properties of these welded joints. Hardness measurements were carried out in accordance with PN-EN ISO 9015-1: 2011. The tests were carried out using the Vickers method, with a load of 49.03 N (HV5). It was shown that the hardness of welds is intermediate between the hardness of base materials, where hardness in the HAZ (Heat Affected Zone) area is higher on the 2205steel side.
