Correct option is A
The complete resistance spot weld cycle is typically divided into four parts:
1. Squeeze Time: The electrodes apply pressure to the materials to be welded, ensuring proper contact.
2. Weld Time: Electrical current is passed through the electrodes, generating heat at the contact point and forming the weld.
3. Hold Time: The pressure is maintained while the weld cools and solidifies.
4. Off Time: The electrodes are released, and the welded materials are removed from the welding machine.
These four stages ensure a strong and consistent weld is produced.
