What is resistance welding?
The two pieces of metal to be joined are squeezed together by the electrodes on the welding machine so they are in good electrical contact.
Then electric current is passed through them, heating them until they begin to melt at the spot where they are in contact.
The molten metal from the two pieces flows together; then the current is turned off and the molten metal solidifies, forming a solid metallic connection between the two pieces.
The term “Resistance Welding” comes from the fact that it is the electrical property of resistance of the metal being welded that causes heat to be generated when current flows through it.
- We offer a variety of welding processes from resistance welding to inline welding of wire and profile tape.
- We also help to reduce the amount of silver used on electrical contacts by embossing the base metal stamping.
- Automatic welding is often the most cost effective solution to join precious metal contact materials to springs and terminals.
