spot welding
Localized metal joining
Spot welding is a method of joining metal sheets by applying heat and pressure at specific points rather than along a continuous seam.
Electrodes clamp the pieces together and pass current through them, fusing the metal at that spot.
The technique is fast and efficient, widely used in automobile manufacturing: The car body is held together by thousands of spot welds.
