That certainly looked great from the inside while welding, I was not even aware that kind of work could be done with MIG. Thanks again Bob, I learn something new every episode!
Unless and until they do so, simple formula: mm = in × 25.4 alternatively, mm = in ÷ .03937 Note that the first formula is exact, the second is slightly rounded. The actual constant for the division equation is 1 ÷ 25.4 = .039370079 , but 5 decimal points is usually plenty unless you're doing super close tolerance grinding or something :-)
Great info, Bob. Was great to hear what Tim Kinnaman in RI had to say about you-- if you see him at FabTech this year, you'd be doing all his students a big favor by busting his stones ;) Thanks again.
Dang pesky grounds!!! Lol... Before you mentioned the ground, I was wondering if the tip was loose or a little worn.... I've never been lucky enough to use a nice rotating utensil.... But we used to widen a lot of agricultural wheels... You know, little ones.. LOL, 34"-42" stuff.. no matter how good you are, still a lot of work fitting them back up! Made some nice adjustable roller stands, not powered, but worked great!!! Would sit in a chair, lean inside and use my knee to rotate the wheel. Made a lot of money on those.. but a bad fit, took way too long to make right!! Yet another great video Bob!! Thank you!
Bob Moffatt is it just speed. I’m an apprentice steam fitter at a refinery and our fab shop is starting to use the Lincoln STT stuff. I’m still getting the hang of 6010/7018 out, but should be testing in a couple months. Is practicing at home on one of my short circuit machines even close? I’m not allowed to touch the MIG machines at work yet.
Bob Moffatt Thanks Bob. Your videos have definitely helped me make the best out of my practice, especially before I got into my Local and had the teaching resources that the union provides now. I appreciate it, please keep making quality, industry applicable, and funny content, and I’ll keep sending my classmates and younger apprentices your way on TH-cam.
Off topic but I was wonder do you need a respirator/breathing protection all the time or only during certain operations. I am new to welding and was just wondering
I wish I'd of went somewhere with an instructor like you. I've watched a lot of videos of yours. If I had time and was closer I'd look into trying to attend anything I could that you teach. Do you guys do anything in the evening times?
I have a ? For you. I’m looking to get my 6GR cert from a fixed position. I believe the hall is using. .068 -233 wire. I went to get it before, but I was in a hurry, (headed out of town), I murdered the cover. The pipe is fixed at 45 degrees. Can you school me in the best way to accomplish this test? Thanks for your time.
@ 3:15 the welder starts to act up just like mine did before it fried the board...But on a positive note the board was only fried for 24 hours...Then it self repaired itself....
@@perenberger1 I worked along side a bunch over the years. Just couldn't get in our local. Soon as I moved to Vegas they opened the flood gates and let anyone in. SMH.
Yeah, it’s a little easier now. I had to have a referral or else I would have had to been a helper for a couple years. You older boys have a lot of knowledge and I enjoy learning tricks and tips from you.
Yeah....back in the early 2000's I was doing a lot of steam vessels, carbon steel, pipes, tanks...all welds were full pen, V-up, .035", C02, from the outside....30+ year old Linde MIG power source/feeders. Pipes from 2" up to 24", tanks from 78" OD, 5/16"-1/2"wall....no grinding in there, or on anything outside after the welds...! Poke a wire through, you're out of there... Tests were done on the 1" plate coupons, cut from 1" wall thickness pipe, 6G.... With the newer welding power sources, and mixed gasses these days, that would be a walk in the park... Plenty of TIG stainless there too...also the antique Linde stuff....
@@bobmoffatt4133 ...Employer bought the stuff at an auction, 2 TIG, 3 MIG...I had to de some repairs on them, they were all actually made by Miller. I bought a Miller-Matic 200 in 1981 when they first came out....hi-lo plugs for voltage and 6 position step switch...still works great....I had a welding shop and ran over 300 rolls of .035, 33# rolls.... And, my Mother was born and raised in Topeka, went to KSU and I still have the Jayhawker mascot figurine....so I guess you're alright...……!
Laugh all you want. I was called in for a pipe test. First up was a 6g 6". Not really a problem . No one in my circle had every dreamed of mig on pipe, let alone heard of it. The next test was 2" xtra heavy. 4 tacks. Mig root and one pass dual shield out with a hand rollout. Yeah simple...... I would have rather done the whole thing with 6013...
I'm adding this here because I don't usually do this social media stuff any more just so tall know the US Navy developed 80% of welding processes that are used to this day . And the only thing the navy will use mig (gtaw) for is aluminum that is the only material one can get an mig x-ray qual. in because in any other material it remains to soft to the point of a ER70S-? Remains to soft and must be heat treated and I don't mean a little soft . Fresh out of the navy as a high pressure pipe welder (4955 code ) I worked for a company that built these three chamber cabinets out of 2"plate the largest side of this behemoth was the back it had to weigh unattached by its self 12-15,000 pounds (the finished cabinet was 86,000 pounds ) in layering the plate steel together I would have to flip this piece over and I would do this by either welding a steel ring with a 2" wall thickness on to a side in order to lift it with mig er70s-3 or 1/8 7018 now the 7018 I could apply one healthy bead ( about a 3/8 root), where as the er70s-3 I could put a root and two covers and it would tear at the first attempt at lifting it . Mig is crap and should never ever be used for pipe because no one is out there heat treating it . Now you may say that the Navy ships use mig welding in their construction all the time . You would be wrong the Navy does not the private company that is building the ship is and our crooked goverment in a complete disregard for the safety of its Navy personnel allows these companies to "except responsibility " for any failures.
There is more GMAW and FCAW wire types out there than you can count. Your experience is not evidence that GMAW is not strong or not safe. All welding processes have the ability to produce the same quality welds. Asuming your weld was mild steel (beacuse you used er70 filler) there is no point in heat treating it because the steel is not heat treatable. If you were welding mild steel to a high carbon steel then the joint should be pre heated to at least 450*F for 2" material, welded and left to cool in still air. If you were welding 2 pieces of high carbon steel then you were using the wrong filler. You should have found an er90 or er100 filler, pre heated, welded, cooled under a blanket or sand and then PWHT the weldment. Furthermore using short circuit transfer for anything over 1/4" is not a wise choice. Use spray transfer in position or pulse spray out of position. If you don't have a machine that can do pulse then use FCAW.
I’ve shot x-ray with mig on stainless and carbon steel...interesting enough they shot clean. I guess that means you’re part about aluminum being the only thing you can get an X-ray quality weld is bs.
@@stout8807 You're right. We do GMAW on mild steel and stainless steel all the time. Steel gets UT and SS gets RT. Both pass no problem. I have qualified our procedures for Charpy to 27Joules at -60*C or better on both GMAW and SAW. I also qualify our new welders on GMAW and SAW on 1" coupons and they bend great all the time. We have had failures but its not the wires fault when the entire root is not fused lol.
Geoff Moore what I don’t understand, how people think ER70s6 is different wether it’s mig or tig wire. Most people I talk too that doo pipe with gmaw, run a mig root and either spray, spray pulse, or fcaw the rest of the way out. I’ve done some short circuit all the way downhill on .280 6” and have had great success. I guess some people don’t understand why why there is PQR and a WPS.

Bob video never disappoints. Always something to learn from.
Hey Bob, next time can you show the fill and cap using flux core process? Thanks. Great video by the way. I have learned a lot by watching you.
Could you add metric measures for us who don't use inches like wire speed and wire diameter. Thanks for great content.
Unless and until they do so, simple formula: mm = in × 25.4 alternatively, mm = in ÷ .03937 Note that the first formula is exact, the second is slightly rounded.

Would you ever consider a GMAW-P fill and cap? Love the short circuit root, super efficient if you have the right settings
I did this it's called Rmd welding tricky but once you get the hang of it, it goes in like butter
I hate when you clean it before you show the weld.
We will keep that in mind. Sorry about that.
Was thinking the same thing!!!!!! It should be the most important thing in a welding video.
Good stuff Bob👍👍
How does the short circuit compare to the RMD or STT processes that some more advanced production machines have?
Those advance processes are sweet. A bit faster too.

Have you ever worked with Lincoln STT on pipe before Bob?? I did some in open root stainless before with it and it worked great!!
I'm doing this at work now but killing to much time cleaning between passes any tips on what I can do to improve productivity
Thank You Bob.
Good vid. Turn and 🔥 burn!
Awesome speed!.. please show us the weld, before grinding it...
@0.14 Thanks for the shoutout! It's my first outstanding achievement on yt!
That was fast wicked nice
When are you going to do the fill & cap? great video
Well get er done for you. Coming soon
Sweet video!
Good good stuff 👍

what are your settings?
Bob do a video for uphill mig roots
We have.
Were you dragging / going backwards for this?
Yes, the more you point the gun up .. like if u r at about 9 o clock you'll get a thicker root
Nice root

You were whipping the wire pretty fast. What was your wire feed speed? Voltage? You sure do nice work
Camera may have made it looked like I was going back and forth faster than I actually was. I like the tick tock back and forth. 18V, 200-225IPM
Yeah he wasn’t whipping it’s the camera you can’t whip that easy with a positioner.
Man I was hoping he would do a flux core pass since he was talking about it
Coming soon...

Pretty much, but after a while in the one type of welding you end up becoming specialized at that and a little bad/rusty at the other stuff.
would like to see you weld a stainless steel pipe butt joint needle purge i can do it but some cant would help alot of new welders
Thumbs up no 101
