Red Seal Welding Practice Exam

Question: 1 / 400

What are oxy-fuel fittings and connections made of?

Steel

Copper

Brass alloy

Oxy-fuel fittings and connections are a vital part of any welding or cutting system. They are responsible for delivering the fuel and oxygen gases to the welding torch and ensuring a steady and controlled flow. While steel and aluminum are both strong and durable materials, they are not suitable for use with oxygen as they can react and cause dangerous sparks or explosions. Copper, on the other hand, is a softer and more malleable material that is vulnerable to corrosion and can lead to leaks. Brass alloy, however, is specifically designed to be used with oxygen and other fuel gases in welding and cutting applications. It is resistant to corrosion, can withstand high pressures, and offers a reliable and safe connection for the delivery of gases. Therefore, the correct answer is brass alloy, making options A, B, and D incorrect.
