Final answer:
The statement that structural standards contain more stringent requirements than pressure vessel standards is false. Welder testing standards can be stringent in both areas depending on the specific application and safety requirements.
Step-by-step explanation:
The statement that structural standards tend to contain more stringent qualification and certification requirements than pressure vessel standards for welder testing is False. It's important to understand that both structural and pressure vessel standards can have stringent requirements, but they vary depending on the specific standard and the application for which it is used. For example, in some cases, the American Society of Mechanical Engineers (ASME) pressure vessel code might have more demanding requirements for welder qualification due to the critical nature of pressure-retaining welds. Such codes are designed to ensure safety, reliability, and compliance with regulations. Welder testing ensures that those performing the welds are capable of doing so to the necessary quality levels required by the design.
