Abstract: The main frame of a bearing type small truck frame is made of sheet metal longitudinal beams and round tube beams. Previously CO2 gas protection welding process was completed by manual on its producing line, the welding quality was poor, high manufacturing cost and serious environmental pollution. Therefore, on the welding line arc welding process was upgraded and transformed with robots. This paper introduces the planning and implementation process of the transformation, briefly analyzes the difficulties and the overcoming methods, empirical reveals the appropriate process parameters of the arc welding robot, and publishes the operation effect of the arc welding robot after the upgrading transformation for peer reference.
