Abstract
A welding tip () for spot welding a first part () formed of conductive metal, for example aluminum, to a second part () formed of aluminum or another conductive metal, such as steel, is provided. The welding tip () includes a notch () at a distal end () and a convex contact surface () extending radially outwardly and upwardly from the notch () for engaging a surface of the first part (). The rotating welding tip () forms a depression () on the surface of the first part () during the welding process. The notch () creates a pin () in the center of the depression () which provides a fixed axis of rotation for the rotating welding tip () and prevents the welding tip () from moving radially relative to the fixed axis, thereby improving the quality of the final spot weld () and reducing process time.
