In the present study, the on-line measurement of the specific index reflecting the welder skill level has been experimentally studied for the purpose of human skill quantification. Three welders with different level of skill performed the TIG (tungsten inert gas arc welding) welding task of first layer on single V groove in a flat position with different welding conditions. It has been confirmed that the specific behavior of the welder with different skill level has been successfully estimated.
