Brazing
Brazing is a method of joining metal parts together, similar to welding but using different temperatures and techniques. It's commonly used in HVAC (Heating, Ventilation, and Air Conditioning) work to connect copper pipes and components. Unlike welding, brazing uses a filler metal that melts at a lower temperature than the pieces being joined, making it ideal for creating strong, leak-proof connections in air conditioning and refrigeration systems. When you see this term in resumes, it indicates that the candidate has hands-on experience with installing and repairing HVAC systems.

Example Interview Questions
Senior Level Questions
Q: How do you ensure quality control when training others in brazing techniques?
Expected Answer: A senior technician should discuss safety procedures, proper flame adjustment, cleaning methods, and testing procedures. They should mention their experience in supervising others and common mistakes to watch for.
Q: What methods do you use to test brazed joints in critical systems?
Expected Answer: Should explain pressure testing, visual inspection techniques, and quality assurance procedures. Should mention specific safety protocols and industry standards they follow.
Mid Level Questions
Q: What safety precautions do you take when brazing?
Expected Answer: Should mention proper ventilation, fire safety equipment, personal protective equipment (PPE), and checking surroundings for flammable materials.
Q: How do you prepare copper pipes for brazing?
Expected Answer: Should explain cleaning processes, proper fitting preparation, and the importance of removing moisture and contaminants before brazing.
Junior Level Questions
Q: What is the difference between brazing and soldering?
Expected Answer: Should explain that brazing uses higher temperatures and creates stronger joints than soldering, and typically uses different filler metals.
Q: What basic tools are needed for brazing?
Expected Answer: Should list torch, filler metals, flux, cleaning materials, and safety equipment as essential tools for brazing work.
