Induction leak testing uses which detection aid to reveal leaks?

Induction leak testing uses which detection aid to reveal leaks?

• A. Smoke or Soapy Solution to Reveal Leaks
• B. Visual Inspection Only
• C. Temperature Measurement
• D. Ultrasonic Listening

Answer: (A)

When testing an induction system for leaks, applying a soap solution to joints and suspect areas creates visible bubbles where gas is escaping. This bubble test gives an immediate, location-specific indication of leaks, so you can see exactly where the leak is and how large it is. It’s simple, quick, and effective for identifying leaks along hoses, clamps, and fittings. Visual inspection alone can miss leaks that aren’t visibly open, temperature measurement won’t reliably show a leak unless there’s a detectable thermal difference, and ultrasonic listening requires special gear and conditions. The soap solution approach provides a clear, direct signal of leaks, which is why it’s the best choice here.
