Pipe welding certification

Postby Ski-Weld » Mon Mar 07, 2016 11:14 am

Hello everyone!
I am new to the blog, but I have been following Jody on Youtube for some time. Anyways, I have been welding cross-country pipe for 8 years now, and I want to get into power plant and refinery work and need to pass some certs. Everything I have done before has been XX10 (6010, 8010) electrode all welded downhill. What I am needing to tackle now is a 6010 root with a 7018 fill and cap. To my understanding, isn't the 7018 fill and cap done uphill? I am asking this because I am currently taking a night welding course and the instructor is telling me that his test is welded downhill on one side of the pipe and then uphill on the other. Anyone ever heard of this before?

That sounds interesting. I've never heard of it but he may have had a weld procedure written up to cover both. My certs on pipe are technically all up progression.
I have more questions than answers

Procedures that are written in accordance with ASME Sec IX can have uphill and/or downhill progression. There is some allowance for multiple variables to be used in a single coupon so what is being done may be valid.

I just find it confusing since the information I have from Lincoln on 7018 says that it is good for all positions except vertical down. I have class tonight, so I'll be able to go over it more with my instructor to clear things up.

Thanks for the replies

Does anyone know of a 7018 rod that is endorsed by the manufacturer for the vertical down position?
I've looked but had no success yet.

7018 is not a down rod

Supposedly so but there has been alot of talk about it including use in qualified procedures and in formal training. Some state there are specific 7018 rods for this purpose.
Personally I don't think a wps is valid if it nominates a rod for a position not validated by the manufacturer. Also a I don't think a good trainer would do so either.
This is their chance to turn here say into fact.

The 1 in the 7018 means it's designated for any position.

Run a 7018 downhill and take a grinder to it. Then do the same with a 6010.

That's not the point. I want the people who claim to have used down hand 7018 rods to tell us the make and part number of their rods so we can verify with the manufacturer that they actually exist.
