Cut Welds

Spot welds are a common metal fabrication technique.

Many household items are assembled using spot welds. Spot welds are small welds that hold two pieces of metal together in place of screws or rivets. If you attempt to service or repair an appliance that is spot-welded together, it is first necessary to cut the spot welds. Spot-weld cutters are available at most home improvement and automotive parts stores. The cutters are inexpensive and relatively easy to use. Does this Spark an idea?


1. Clamp or otherwise secure the spot-welded item to prevent it from moving.

2. Place a metal punch in the center of the spot weld and strike it sharply with a hammer.

3. Chuck the spot weld cutter into a drill according to the drill manufacturer's instructions.

4. Place the center of the spot weld cutter into the depression in the spot weld created by the metal punch.

5. Hold the cutter flush to the welded surface. Drill slowly until the cutter is through the weld.
