Abstract: A welding electrode for an electric resistance welding process. The welding electrode includes a body extending along a center axis and terminating axially at a weld face for contacting a work face. The weld face defines a center along the axis and defines an outer edge spaced radially from the center. A plurality of senates are defined along the weld face. Each of the serrates projects axially away from the weld face and extends radially from the center axis to the outer edge of the weld face. A higher density of the plurality of serrates is formed proximate to the center axis than proximate to the outer circumference of the weld face. Methods for using the welding electrode and forming the senates on the welding electrode are also provided.

Abstract: A low-cost tip dressing cutter causing no accumulation of swarf around a breaker is provided. A surface of a breaker 5 facing a cutting plate 4 corresponds to a recessed surface 52. The diameter of the recessed surface 52 gradually decreases with increasing distance from the outer periphery of the recessed surface 52 facing the cutting plate 4 in a direction opposite to the cutting plate 4. A through hole 51 is formed at the center of the breaker 5, A screw 6 inserted through the through hole 51 is screwed to a fastening hole 33a of a holder 3 to attach the cutting plate 4 to the breaker 5.

Abstract: A small camera module is simply assembled in a short time, while reducing displacement of a camera relative to the first and second frames. Specifically, the camera module is assembled by bending a pair of clips to engage engaging portions of the clips with engaging recesses of the first and second frames to fix the first frame, camera holders, and the second frame, with the first and second frames located at both sides of each camera holder with a housing recess facing outward, and using resilient force of each of the clips to press the camera with a projection of the clip.
