Abstract
The study investigated the effect of an arc-weld made with a tungsten electrode on the mechanical properties, the specific resistivity and microstructure of Inconel 718 alloy. Static tensile tests were carried out on micro-tensile specimens deformed in a static tensile test at temperatures of 600-900 °C and as a reference at room temperature. The results showed strength properties of the joint at a level comparable to the base alloy. Mechanical stability was maintained up to 650-700 °C and deteriorated rapidly at 750 °C, where a phase transformation occurs. The microstructure in the remelting zone shows strong fragmentation of the grains and the presence of a large amount of gamma”-phase (gamma double prime) precipitates forming dendritic structures. The hardness in this zone shows a decrease from 500 HV0,2 of the non-heat affected zone material to 260 HV0,2 in a fusion zone. At the same time, a decrease in the specific resistivity of the remelted material by about 10% compared to native Inconel 718 is observed.
