Answer: B. Remove all dirt, grease, oxides, and coatings from the joint area using mechanical cleaning or chemical flux
Proper soldering requires clean surfaces free of dirt, grease, and oxides. Mechanical cleaning (wire brush, sandpaper, emery cloth) and/or chemical flux removes contaminants to allow proper solder wetting and adhesion.
What is 'Galvalume' and how does it differ from standard galvanized steel?

- D. A brand name for stainless steel
Answer: B. Steel coated with an aluminum-zinc alloy (55% aluminum, 43.4% zinc, 1.6% silicon) providing superior corrosion and heat resistance
