Acetylene welding is a process in which like metals are joined by heating them to their melting temperature with an oxy-acetylene flame produced by a torch.
oxygen and acetylene
Because of all the gas combinations used with this process Oxygen and Acetylene, in correct proportions, produce the highest flame temperature.
You answered your own question. Oxygen and Acetylene. Other mixes are now used in place of Acetylene so the process is now called Oxy-Fuel.
Used in welding metals, the reaction of acetylene with oxygen has = -1256.2= -1256.2 .
Oxygen and acetylene tanks feed into your torch. When opened, the gases will mix in a chamber in the torch, then flow out of the torch tip. Using a spark lighter, they will ignite causing a flame. This flame can be adjusted to a neutral flame by moving the knobs on the tank regulators.
You have oxygen and acetylene to blend into the tip for a flame. It will be regulated by adjusting the regulators on the bottles and the welding handle will have adjusting ability for the temperature you need for the metal you are welding.
Acetylene.
Acetylene uses:- welding- metals cutting- feedstock for plastics and acrylic products fabrication
n - Oxygen and Acetylene are the original gasses that are used for welding/cutting. Newer mixtures are slowly replacing Acetylene as a fuel. These gasses don't always reach the temperatures attained by Acetylene. Us old-timers still prefer Acetylene.
By using insulating gloves and using gas welding instead of electric arc welding.
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
