After brazing a joint in a very tight location, which instrument would be used to determine if the joint is properly brazed?

• A. Magnifying Glass
• B. Endoscope
• C. Inspection Mirror
• D. Bright Flashlight

Answer: (C)

Visual inspection of a brazed joint in a tight space relies on seeing the joint without disassembling components. An inspection mirror lets you view the joint from angles you can’t directly see, reflecting light and allowing you to check the brazed fillet for proper wetting, even coverage, and the absence of gaps or voids. The other tools aren’t as effective for this specific task: a magnifying glass can magnify but won’t help you look around corners; an endoscope is more specialized equipment not usually at hand for basic HVAC brazing inspections; a bright flashlight lights the area but doesn’t improve your line of sight. So, the inspection mirror is the best choice for verifying a properly brazed joint in a very tight location.
