Abstract
The process of robotic TOPTIG welding of thin-walled T-joints and butt joints of nickel alloy Inconel 718 was developed. The welding installation TOPTIG 220 DC provides a wide range of adjusting the parameters in the process of non-consumable electrode inert gas welding with mechanized filler wire feed and possibility of robotizing welding in the places with a limited access to the weld zone. Based on the results of investigations of robotic TOPTIG welding, the technological features of making T-joints and butt joints of thin-walled parts of Inconel 718 alloy were determined. The measuring system of the installation provides registration of technological parameters of welding process, signaling about deviations from the preset values, formation of database on welding technologies and the possibility of their viewing. The carried out certification showed that the developed welding technology meets the requirements of standards ЕN ISO 15614-1 and ЕN ISO 15613. 7 Ref., 1 Table, 7 Figures.
