Pressure pipe Certs?

by Bill

I have a couple of questions. I have certs in 6G pipe with AWS. My first question is: Am I qualified to weld steam pipe at 120 psi.? If not what is the maximum pressure I am still certified for?I know that ASME has there own certs but who determines which certification is needed for these type of welds?


Bill, AWS and ASME certs do overlap a little bit but it is usually up to the engineering authority of your employer or contractor that makes the call on the questions you ask.
