An arc welding process that uses flux coated rods is called what?

1. MIG welding

2. Stick welding

3. TIG welding

4. Wire welding

The correct answer is: MIG welding

An arc welding process that uses flux coated rods is called stick welding. In stick welding, an electric current forms an arc between the welding rod (which is also known as the electrode) and the metals being joined. The flux coating on the rod melts and creates a gas shield and slag layer, protecting the molten weld pool from atmospheric contamination. This process is often used for its simplicity and versatility in various applications. Option A, MIG welding, involves using a wire electrode on a spool that is fed through a welding gun and is shielded by a gas. Option C, TIG welding, uses a non-consumable tungsten electrode with a separate filler material if needed, and it also uses a shielding gas. Option D, wire welding, can refer to several processes that use a continuous wire feed, such as MIG welding or flux-cored arc welding.
