Final answer:
A welder who has qualified to CSA Standard W47.1 is automatically qualified at a new certified company, although additional assessments or training might be required by the company's policies.
Step-by-step explanation:
When a welder who has qualified to CSA Standard W47.1 moves from one certified company to another, the welder's qualifications are typically transferable provided that the new company is also certified under the same standard. CSA Standard W47.1 outlines the requirements for welders concerning qualification tests, and certification protocols are put in place to ensure the consistency of welding quality across the industry. Therefore, if the welder has already qualified under this standard, they would be recognized as qualified at the new company without having to requalify with a new test assembly.
However, it's important to note that while the qualification itself may transfer, specific company policies or project requirements might necessitate additional testing or training. The certification is based on the welder's ability to perform to the standards set by CSA W47.1. Companies are responsible for ensuring that the welders employed are capable of performing the work according to the code and often will assess the skills of the welder as per their own quality control programs. It is always best for the welder to check with the new employer about their policies.
In summary, the correct answer to the question is b. Is automatically qualified at the new company, with the understanding that additional assessments or training may be required depending on the new company's policies.
