About 6-G or 6-GR welding certificate

[Dean125125]

Hello to everyone , i am new to this forum and i am happy to find such a place , for first i would like to ask you , what kind of certificate is this - 6-G or 6-GR welding certificate - . Please answer , i don't know because i am from Macedonia , and where can i get such certificate .
Thanks to all who are going to post .

It is a position of pipe welding, sometimes called "Arkansas Bellhole." It's done with the pipe in a 45 degree angle. It is not one single certification though. You certify on things based on many variables, such as base metal, filler metal, process, and more. The position is only one of these variables.

Another name for it is 'skunk', once you know what your doing it's easier than the normal 5G.

6G and 6GR are the positions in which the qualification tests are performed by the person qualifying.
These can be found in Codes such as AWS D1.1 or ASME Section IX.
Log onto AWS.org and you'll find D1.1 there.

Brian, I'm sure you had a SLIGHT slip of wording here, and know better, based on the sound of your post...but I don't want to have the original poster mislted by it if he catches it.

6G and 6GR is not THE only positions used. In other words, you can qualify in other positions, such as 1G (flat), 2G (horizontal), etc..

The 6G is most common, as passing it will also qualify you for all other positions.

Personally, I've always heard 6G, not 6GR, but I'm betting that it's the same thing, correct?

6GR is just 6G with a restriction plate to make it that much harder.

I have heard of that, just not called 6GR. I've never had to take a test with a restriction, but of course after many years in the field, you run into the real deal, not just a simulation.

I don't recall any of the codes calling out a specific size plate, or distance from the weld, though. Have you guys run into this anywhere, or is it just whatever the company wants to do with it?

The last 6GR I took was on 2" sch 120 with carbon tig root followed by pass of 309 tig then 309 smaw fill with 7018 cap according to our QC/wps guy it's suppost to qualify you for more materials I took my test at an aws certified school in barberton oh look in the phone book and see if you can find anything in your area or call some local welding shops that are in the pressure vessel industry they should know where to tell you where to go.

I've been a few places that they had you test on carbon pipe, but with stainless filler. It qualified you on stainless and carbon steel pipe. It's the way some codes are written, but I don't agree with this one. It's MUCH easier to weld carbon steel pipe with stainless filler than stainless pipe with stainless filler.

I've never heard of them having a test with a carbon root and stainless filler the rest of the way.

That s/s wire on carbon is a good cheat when your doing amonia (sp) when the oil won't stop running. Bang a purge up it the do the bottom with the s/s filler through the oil then carry on like normal with the carbon wire. An old sneaky welder told me that one.

As for testing with ss on carbon pipe, well that's making it to easy.

Here is a page with a picture showing the 6GR setup. http://www.weldinginspectionsvcs.com/6grSample.htm

seems that you can take the 6G test and if you pass it, and through some companies are pre-qualified for welding in other positions, 1,2,3,4G positions
I would rather run a 6G heli-arc than 4G anyday

AWS D1.1 and ASME IX both say that welding 6g covers you for all other positions.
