A spot weld is a join that has been spot-welded.
Spot welds are made by pressing electrodes against both sides of the metal parts to be joinedand passing a high current through them.
Spot welds are mainly used for joining parts which will be stressed in such as way that thewelds are in shear.

If two pieces of metal, especially wires or sheets, are spot-welded, they are joined by melting small circular areas on the metal using heat from an electric current and pressure.
The metal sheets are spot-welded by concentrating an electric current on a small spot, melting the metal there andforming a weld.
On ice-skates, the steel blade is spot-welded to the tubular frame.
