On a job application, John states he has experience soldering pipe. What is the best way to determine his soldering ability?

• A. Review his references
• B. Have him perform a short test off site
• C. Watch John solder pipe
• D. Request a video of previous work at another job site

Answer: (C)

Direct observation of hands-on work is the most reliable way to judge soldering ability. Seeing him actually solder pipe lets you evaluate the real workmanship: how clean and continuous the joints are, how well heat is controlled, whether flux is used correctly, how accurately the fit-up is prepared, and whether the joint holds under a leak test after cooling. It also lets you assess pace, safety practices, and adherence to relevant codes in real job conditions. While references, videos, or a brief off-site test can provide clues, they can’t reliably show current performance under realistic conditions. A live demonstration on the job site gives immediate, tangible evidence of his capability and consistency.
