Arc welding is defined as?

• A. friction welding
• B. laser welding
• C. using an electric arc to fuse metal
• D. ultrasonic welding

Answer: (C)

Arc welding is defined as using an electric arc to fuse metal. The electrical arc between an electrode and the workpiece generates the intense heat that melts the metal at the weld zone, allowing the pieces to fuse as the molten metal cools. Depending on the process, filler metal and shielding (gas or flux) may also be involved to protect and complete the weld. This sets arc welding apart from other methods: friction welding relies on heat from friction, laser welding uses a focused laser beam, and ultrasonic welding uses high-frequency vibrations to create the heat and join the materials.
