The fuel used for welding metals is a mixture of:
Ethyne and oxygen
Ethyne and hydrogen
Ethyne and carbon dioxide
Ethyne and nitrogen
Acetylene (ethyne) is used for oxy-acetylene welding at very high temperatures and these temperatures are obtained when ethyne burns in oxygen.
A mixture of oxygen and ethyne is burnt for welding can you tell why a mixture of ethyne and air is not used?
