You can gas-weld low-carbon steel with great success, using the inexpensive mild-steel welding rod you can buy at any hardware store.
No, chlorine gas cannot melt stainless steel.
Pressurized cylinders for LPG are made of steel.
hydrogen methane
Yes. Argon gas welding is often used for killed steel welding to inhibit the oxidation of the steel.
That greatly depends on the type of steel you are welding, but you should be safe with a CO2 Argon mix, otherwise known as Steel mix, it is good for mild to medium grade steel.
carbon steel pipe used for oil and gas transmissions
Carbon dioxide gas is formed in steel cans when storing fruit. This occurs due to the respiration process of the fruit, where oxygen is consumed and carbon dioxide is produced in the sealed environment of the can.
Carbon cannot be broken down. It is an element. When you burn carbon you get carbon dioxide, but that forms from combining carbon with oxygen.
A gas cannot boil. Boiling is the transition from liquid to gas.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
Yes, aluminum can be welded together using various welding techniques such as TIG (tungsten inert gas), MIG (metal inert gas), and stick welding. Proper preparation, equipment, and technique are important for achieving a strong and clean weld when working with aluminum.
You can't change the chemical properties of a compound without changing what the compound is. Carbon dioxide cannot become a combustible gas and still be carbon dioxide.
