OAW stands for?

OAW stands for?

• A. Oxy-arc welding
• B. Oxy-acetylene welding
• C. Oxygen-arc welding
• D. Oxygen welding

Answer: (B)

OAW is the standard shorthand for oxyacetylene welding, a process that uses a flame produced by burning acetylene gas in oxygen to heat and melt metal for welding. The fuel is acetylene and the oxidizer is oxygen, and this combination creates a versatile flame used with a hand-held torch. That specificity is why this term is correct: oxyacetylene welding is the well-established name for the method. Other options don’t fit because they either imply an electric arc or don’t name the fuel gas clearly. Oxy-arc welding isn’t a commonly used term and would suggest an arc process, which isn’t how oxyacetylene welding works. Oxygen welding alone is vague and doesn’t identify the fuel gas (acetylene) that makes the process distinct.
