Which activities require a California C-60 Welding Contractor license?

• A. Bidding, contracting, supervising, and performing welding for others on welded structures in shop or field.
• B. Only performing welding in your own shop for private use.
• C. Inspecting welding without a contract and for personal projects.
• D. Welding maintenance for equipment not used in construction.

Answer: (A)

A California C-60 Welding Contractor license is required whenever you bid on, contract for, supervise, and actually weld for others on welded structures in shop or field. That description matches the option that includes those activities—bidding, contracting, supervising, and performing welding for others on welded structures. The license isn’t needed for welding you do only in your own shop for private use, nor for inspecting welding without a contract or for maintenance work on equipment not used in construction. In short, if you’re offering welding services to paying customers as a contractor and taking on projects, the C-60 license is required.
