Gas welding.

The flame temperature when burning Propane in Oxygen is 2800 degree C
• The flame temperature when burning Acetylene in Oxygen is 3100 degree C
Propane (also called LPG—liquefied petroleum gas—or LP gas) is a widely used fuel. It is transported and stored as a very cold liquid, and can cause a “freeze burn” or frostbite if in contact with the skin.
The liquid propane is turned into a gas inside a tank or a cylinder. In its natural form, propane is colourless and odourless. To make propane easier to detect in the event of a leak or spill, manufacturers add a chemical compound to give it a distinctive smell.
Welding
Firstly: Propane cannot be used for Gas Welding. When acetylene burns in oxygen, it creates a reducing zone that cleans the steel surface. Propane do not have a reducing zone like acetylene and can hence not be used for Gas Welding.
Acetylene has more versitility to do welding, heating, anealing, cutting and many other options,because it has high flame temperature.
Propane is used for fueling your home's furnace because of low boiling point.
acetylene
because this is highly flammable and easily available
