Final answer:
Laser Welding is similar to spot welding as both use high-energy sources to melt and fuse metals at the joint. This method is precise and does not require any extra soldering material.
Step-by-step explanation:
A bonding process similar to spot welding of metals is C) Laser Welding. Spot welding and laser welding both utilize high-energy sources to locally melt the metal at the joint, enabling them to fuse together upon cooling. Both processes are used for their precision and ability to join metals without the need for additional soldering material. Unlike adhesive bonding, which uses chemical substances to bond materials, and ultrasonic welding, which uses high-frequency vibrations, laser welding uses a concentrated beam of light to generate the heat necessary for joining metals. Friction stir welding, meanwhile, is a solid-state joining process using a non-consumable tool to generate frictional heat and plastic deformation at the welding point.
