The Anesthesiologist
AnswerNitrogen is used to prevent porousity in the welding member by preventing oxygen and air from entering the molten metal during the welding process. Other gases are also used for this purpose such as Argon, Helium, Carbon Dioxide, and the gases given off when the flux burns away during SMAW (stick) welding.They provides a shielding effect which make a barrier between the outside oxygen and molten metal.The formation of oxide reduce the strength of the weld.
methane gas
Toxic gases.

Sure. Nuclear power plants give off effectively no gases of any kind.
The Anesthesiologist
anesthesiologist
It is an anaesthetist.
an anesthesiologist, I assume. I don't know quite what you mean by "gases". They administer anesthetic gases in addition to other agents
A funny term is a gas passer but the proper term is an anesthesiologist. She is a medical doctor (MD) who cares for a patient before, during and immediately following a surgical or medical procedure by administering appropriate anesthesia and monitoring the patient for reactions and complications, and to ensure comfort and manage pain.
The waste gate controls the boost coming out of a turbo by bleeding off exhaust gases/pressure to the turbo's turbine. By control the amount of gases/pressure the turbine see's, it controls the turbo's speed/pressure.
Exhaust stroke.
Respiratory
Glowing gases observed during combustion is called a "flame."
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
gases emitted during volcano eruptions are basically oxides of shulphur,etc
exchange of gases and nutrients in the blood; pumps blood and controls heart
