A pipeline test can be won or lost before you ever strike an arc.
Christian and I were doing a little pipe welding practice, so I figured I’d go over some of the basics I’ve learned over the years when fitting up for an X-ray pipeline test.
Line up your seams.
Pay attention to your high-low.
Know where you’re putting your tacks and why.
Understand how that pipe is going to move once you start putting heat into it.
There are a hundred little things an experienced pipeline welder does without even thinking about anymore—but when you’re learning, those little things matter.
This isn’t the only way to do it. It’s just some of what I’ve learned from taking tests, welding X-ray pipe, and working around a lot of good welders over the years.
That’s part of why I like showing Christian this stuff. You can tell somebody how to do it all day, but eventually you’ve got to fit it, tack it, burn it, and learn what that pipe is going to do.
Pipeline welders—what’s the #1 piece of advice you’d give somebody getting ready for their first X-ray test?
