Robot FCAW Technique Hytrodynamic Torque Converter

According to the weld connector shape of top cover joint block of hytrodynamic torque converter, dynamic balance characteristic in use, higher seam metal performance index and zero defect for welding quality. To meet the requrirements, the robot+position-changeable flexible welding system is used to solve the key technical problems of geometric dimension consistency, symmetry, in space position and metal filling homogeneity. The rational arrangement among the welding power of the robot system, position changer and wire feeder is described. The FCAW technological parameters of the top cover joint block of the hydrodynamic torque converter and the technological measures of preventing the welding defect are determined through the technological test.
