The gas used in welding and cutting metals is _______.
Ethyne
The gas used in welding and cutting metals is Ethyne.Welding and cutting of metals require high temperature. The combustion of ethyne with oxygen produces a flame of over 3,600 K (3,300 °C, 6,000 °F), releasing 11.8 KJ/g, thus making it appropriate for cutting and welding.
