Final answer:
The Canadian Welding Bureau issues a nontransferable card to welders who qualify for the vertical down process of welding. If a welder does not qualify on a standard test assembly, no card is issued.
Step-by-step explanation:
The type of identification card issued by the Canadian Welding Bureau to welders who qualify for the vertical down process of welding is nontransferable. This means that the card cannot be transferred to another individual. It is specific to the person who qualified for the vertical down process of welding.
Welders who meet the qualifications for this process are issued a nontransferable card as proof of their skills and certification. The card serves as an identification and verification of their ability to perform the vertical down process of welding.
The Canadian Welding Bureau does not issue a card if the welder did not qualify on a standard test assembly. Therefore, the correct answer to this question is D) no card is issued because the welder did not qualify on a standard test assembly.
