摘要： A spot welding system includes a spot welding gun, a robot, and a tip dresser that polishes a face of electrode. The tip dresser includes a blade that cuts the face of the electrode and a blade driving motor that rotates the blade. A dresser control section of a control device detects torque of the blade driving motor. When the torque of the blade driving motor exceeds a predetermined torque upper limit value, the dresser control section carries out speed reduction control that reduces the rotation speed of the blade driving motor.

摘要： A method is disclosed for using welding electrodes with a spherically-domed welding face having concentric contoured features formed into the face for better contact with workpiece surfaces. The concentric contoured features may be initially formed by rotating a cutting tool with a contoured cutting edge, the cutting edge being in engagement with the electrode face. A similar practice may be followed to re-create the weld face surface geometry if it becomes eroded or malformed during welding use. A suitable tool may have a blade-like geometry, with a mounting portion for supporting and positioning the tool in a rotating holder and a cutting edge. The cutting edge may have a contour complementary to that of the weld face and extend at least from the center of the weld face to at least the radial extent of the concentric contoured features.
