Every welding standard and code has specific acceptance criteria. One must know what standard is being used to provide a valid response.

Even ASME piping codes can have multiple responses to this inquiry depending on the operating temperature or service class. A piping system operating at high temperature or classified for high pressure fluid service is more restrictive than for other applications.
