An approach was proposed to create the technology for TIG welding of structure elements of complex geometric shapes of stainless steel using a adaptive robotic system, which allows adapting to changes in the surface shape of workpieces during welding process and minimizing the probability of arising the defected welded joints and temper colors on the workpiece surface. The technology of robotic non-consumable electrode welding of fillet joint of thin-sheet structure elements of stainless steel of AiSi 304, 210, 430 grades with a thickness of joined sheets from 0.8 to 1.5 mm was developed. The results of welding experiments showed that the developed algorithms of interaction between technical means of adaptation can be used in automatic control systems for TIG welding process. 5 Ref., 2 Tables, 10 Figures.
