Abstract

Presented are the results of mechanical tests of EP718 welded joints obtained by robotic melted electrode welding with reduced heat input. According to the results of the study, it has been established that the static strength of welded joints obtained by robotic consumable electrode welding at room and elevated temperatures is in line with the requirements for joints obtained by non-consumable electrode argon-arc welding.
