Where can you weld anode to tank?

Where can you weld anode to tank?

• A. Anywhere on the tank
• B. Only on saddle plates
• C. Only on the valve stem
• D. Never weld anode to tank

Answer: (B)

Anodes are used to protect the tank from corrosion by providing a sacrificial metal that corrodes instead of the steel. They must be welded to the tank in a spot that ensures solid electrical contact with the metal surface. The saddle plates are the proper place because they’re structural, accessible for welding, and provide a continuous metal path to the rest of the tank, so the protective current can reach the entire tank surface effectively. Welding an anode to the valve stem or placing it anywhere else can risk damaging the valve or coatings and may not give a reliable electrical connection. So, the correct location is on the saddle plates.
