However subsequent extension of the use of this process to other ferrous and non-ferrous metals led to the use of CO 2 nitrogen as well as the mixtures of argon helium oxygen hydrogen CO 2 and the like.

Example of gas welding. The electrodes used in carbon arc weldin. As initially this process was used mainly for welding aluminium and stainless steels with inert gas shielding it is more popularly known as metal inert gas MIG welding. This is because gas pressure welding is superior to other joining methods in its workability.

There are 10 different gases including Argon CO 2 Oxygen Helium Nitrogen Hydrogen Acetylene Propane Propylene and Compressed Air. Gas Welding Principle Equipment 3D animation - YouTube. This heat is further used to melt interface surfaces of welding plates which are held together to form a joint.

Gas welding involves the use of a gas-fed flame torch to heat the metal work piece and the filler material to create a weld. Oxy-acetylene gas welding Oxy-gasoline gas welding MAPP gas welding Butane or propane welding Hydrogen gas welding. This is what makes it a best suit for the underwater welding process.

This type of welding is used for small torches to make jewelry. Thanks to these features the neutral flame is the most used option for gas welding but its not always the best choice. For example an oxidizing flame produces oxidation while a carburizing flame produces iron carbide.

Hydrogen gas welding works off electrolysis where water is split into hydrogen and oxygen is used as well. If the filler material is used it is fed directly into the weld area manually. In radiation mode of heat transfer the.

The combination of the to gases results in sufficient heat to produce molten metal. Most of these gases in large quantities would damage the weld but when used in small controlled quantities can improve weld characteristics. It melts the other refractory metals as well.
