Apprentice's Third Soldering Attempt and Correction

What happens here

Damion attempts his third solder joint, working on a fitting that proved problematic during the demonstration. He carefully heats the joint and applies solder. After cooling, the instructor inspects the joint and determines it is not satisfactory due to incomplete solder flow and signs of potential leakage. The decision is made to cut out the faulty joint and redo it, emphasizing that perfection isn't expected initially.

Goal: Attempt a challenging joint, identify failure, and learn to correct mistakes.
