welding wire without gas in united states

Welding | Encyclopedia

Gas welding, also called oxyfuel gas welding (OFW), refers to a group of welding processes that use gas as the source of heat energy. Oxyacetylene and oxyhydrogen are two types of fuel gases used. Acetylene is commonly used for welding because, when coined with oxygen , the flame temperature can reach 5,600°F (3,093°C), the highest temperature produced by any fuel gas-oxygen coination.
