What does W47.1 certify about a company?

• A. It certifies the product
• B. It certifies the capability in welding and the qualification of personnel and welding procedures
• C. It certifies only personnel
• D. It certifies the equipment

Answer: (B)

W47.1 certification for a company verifies the ability to weld to required standards, demonstrated through qualified personnel and qualified welding procedures. This means the shop has shown its welders are capable of performing the required welds and that the welding procedures it uses have been tested and proven to produce acceptable joints. It’s about the shop’s overall welding capability and the qualification of the people and procedures behind it, not about certifying a specific product or the equipment used.
