Online measurement of manual welding skill

In the present study, the online 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 levels of skill performed the TIG (tungsten inert gas arc welding) welding task of first layer on a single V groove in flat position with different welding conditions. It is confirmed that the specific behavior of the welder with different skill level has been successfully estimated.
