After any method used to join the copper tubing, what is the first task to perform?

• A. Pressurized Leak Test
• B. Apply Heat
• C. Clean And Inspect The Joint
• D. Store The Assembled System

Answer: (A)

Cleaning and inspecting the joint is the first step after finishing any joining method. Cleaning removes flux residues and oxidation that can hide defects and interfere with the sealing and inspection process. A thorough clean also makes it possible to see how well the filler metal has wetted the joint and to spot issues like gaps, voids, misalignment, or cold joints. By verifying these details right away, you ensure there are no hidden problems that could cause leaks when the system is put under pressure. Only after the joint is clean and looks sound should you proceed to a leak test to confirm the system’s integrity. Storing the assembled system isn’t the immediate next task after joining.
