Question

which process is capable of cutting thicker carbon steel?

oxy-fuel cutting
plasma arc cutting

Explanation:

Compare process mechanisms

Oxy-fuel cutting relies on a chemical reaction between oxygen and the base metal (iron) at elevated temperatures to oxidize and blow away the metal. Plasma arc cutting uses a high-velocity jet of ionized gas (plasma) to melt and blow away the material.

Analyze thickness capabilities

Plasma arc cutting is highly efficient and fast on thin to medium materials, typically up to 2 inches (approx. 50 mm) for heavy-duty industrial systems. Oxy-fuel cutting, however, can easily cut carbon steel up to 10 to 20 inches (250 to 500 mm) or even thicker, making it the superior choice for very thick carbon steel.

Answer:

• Oxy-Fuel Cutting (Correct answer)
• Plasma Arc Cutting
