Quizplus · Accepted Answer

Ozone is a gas that is produced by the ultraviolet light in the air in the vicinity of welding operations. Argon and carbon dioxide are commonly used as shielding gases during welding, but they are not produced by the welding process itself. Phosgene is a toxic gas that can be produced when certain materials (such as chlorinated solvents) are subjected to high temperatures, but it is not typically associated with welding operations.
