Spot Welder (Spot Welding)

This is used to permanently join thin plate.  As electricity flows from one electrode to another and resistance to the flow is encountered, heat is produced.  The heat produced is of a high enough temperature to melt, or better, fuse the two pieces of metal together, joining these permanently  to each other.  When the electrodes are removed a spot can be seen where this fusion has taken place.

This method is commonly used in industry for joining car panels together to produce the body of the car.

On display here are a range of methods commonly used to permanently join metal to metal.
