I know I could dig through the aws site and find this answer, but this is easier and more interesting.
I have a guy working for me that had worked for the same company for 20 years as a journey man millwright and needs to get his his certification. He is a very good welder, actually a excellent welder-fabricator, but needs to get his cert. What does he need to do to test ? I couldnt even tell you where his knowledge comes from, I think it was on the job? or school probably 25 years ago. we are located in southern Wisconsin.
