Proper rods on pipe line

DCALLWELD · Fri Feb 28, 2014 7:19 pm

I am a rig welder and do manly repair work to heavy equipment and structural work as of now. I am looking to get more in to the pipe side of things so to speak. I have been practicing on some 6'' shc 40 with some 6010 uphill root and 7018 uphill cap. Getting better with it, after practice. I just recently got a 7' drop of 12'' shc 40 and was going to "play" pipe line in my back yard. Now I am understanding its a down hill root using 6010 but , what is used for a cap? I am understanding its down hill as well and we have all seen the puddle pass up a 7018 down hill. I am running a miller pipe pro as well does any one have any settings in mind for that machine , also what electrode is used for the cap ? thanks

Here's a video on 6010 downhill, he's rolling the pipe but you can see he shoves the rod in there and goes like mad.

7018 will be uphill as usual.

Ok but I'm I'm talking about cross country pipe line and have head something to the affect that it's dun down hill for faster time . They have also said a 70's series rod or 80's rod is that a 7010 or 8010 they are talking about?

Yep, it's common on pipeline to weld all downhill, usually 6010 root, and sometimes the hot pass, for good control, then another --10 rod the rest of the way. There are 7010, 8010, and 9010 rods. I'd have to look, but there may be higher tensile --10 rods as well, since there is a 11018 rod...

Ok thanks for the video links and ok that's what I was thinking on the 70... Series rods I just wanted to be sure befor I by 50 lbs to practice and find out I have the wrong rods and settings down , thanks to both fist time to use a form in my life and seamed pretty easy and helpful.

ok just got one last question so if the only difference in the 6010 and 7010,,,8010 is strength , they should all have the came welding characteristics. With that being said I could just practice with the 6010 all the way out and should be able to do the same thing when I use the higher strength rods correct?

You are correct. these all rods perform similar.
I've used Lincoln 6010 and Lincoln 8010, couldn't tell much difference.
Same with 7018 and 8018.

6010 is the most common for the root but i have heard of 70+ being used for a root pass. 70+ 80+ are usually fill and cap rods. 6010 7010and 8010 all weld so close to the same practicing with 6010 will be fine. I prefer the lincoln 5P+ over the 5P it runs a lot nicer and is closer to running 70+ and 80+. It is common to see large diameter rod like 5/32 and 3/16" for the fill and cap so keep that in mind. If you plan on mainlining get a ditch box you will need it. As for the amperage on that pipe pro I'd start around 80 ish for 1/8". I'm not a big Miller engine drive guy but ive heard they are pretty good.
