- In this one, we have 6 large 316L stainless steel pipe fittings that need to be fit up and welded out. We Tig weld these ones up with the new Dynasty 300 welder. We talk about the process to fit up, and weld out a fitting of this size. hope you guys enjoy!

You could have easily welded all that in the flat position but chose not to in order to show others how to weld when that's not an option. I appreciate your consideration to us all. I really enjoy watching you grow and hope you can keep being a positive influence on generations to come.
Thank you, I try to show real world scenarios for situations that may arise as a fabricator/welder. Thanks for the feedback and thanks for watching!
@@Freedomfabrication777now do it off a tripod pipe vise to add some extra real world! Haha! Good video.
@@TulanePass That's gravy real world, 3" from the wall using a mirror to see the wall side of the weld.
Watching and learning thank you very much 🇬🇧👁️♥️👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
You bet brother, thanks for watching!
Hmmmmm pretty good video, couple things, though. maybe I missed it, but did you mention not bottoming out the fitting into the flange? Also in higher end fab shops they'll give you your money for contaminating ss pipe and fittings by putting them on a CS table, not to mention welding with the gasket surface flat on the table I've work with welding inspectors that would have a stroke if they saw you doing that to their pipe assemblies. I'm aware this is how you do it, but these are pedigree issues in the piping industry. Still a pretty good video and a very nice shop and equipment.
Your spec doesn't call for a gap between the flange and the reducer for expansion?
Excellent work. The welds on the work pieces looked nice and uniform. Yes to see all the tools and gadgets... I have done similar work, and you made it look easy. I have alot of questions but would take up a half page. Thanks for sharing.
Thanks! I would be glad to answer any questions you have. Thanks for watching!
Man it gonna suck wen u call it on the day job viewers like me can't pay u for the content😢 hope we don't get less of it
Great job Stuart, I really like welding stainless and enjoyed the video!
Thank you sir. I also enjoy stainless welding. Very fluid. Thanks for watching.
You doing great job 👏,I'd like to share some of my welding with you mate,but not possible over here 😢 ,if you have some place like IG or Discord I will be pleased to share with you (as professional welder for 22 year's 😅)
Thanks, I appreciate that, and thanks for watching!
Nice work! While it's apparently difficult (reflection/camera focus) to get quality arc shots.....yours looked pretty crisp- Thanks for taking us along.
Thanks, it’s tuff to get your head in there and a camera, all while trying to get a good clear shot. I’ll keep working on it. Thanks for watching!
Nice looking finished product. One point, and it sounds like you’ve certainly welded more socket flanges than I have but, I was taught to always gap the pipe off the flange 1/16-1/8” to avoid weld cracking due to contraction of the weld joint. Your thoughts, please. I do admire that you did all this without a positioner.
Thanks. I have heard that before in regards to the gapping, and I’m sure it doesn’t hurt to do just in case. If I weld the fitting onto a pipeline that has heated fluid running through it, I would do it, but for fittings like these, I’ve never had an issue. I’m sure some would argue that point, but to my knowledge, I’ve never had one crack/leak. I’m sure it’s best practice to be safe rather than sorry. Thanks for the watching!
You may want to invest in a rotary weld positioner with a purge feed integrated into it. This would give you consistent perfect welds once you get the hang of it. They come with a variable speed controller and a foot pedal. I engage the foot pedal (clamp) and then set the speed. This is great for work bench welding. They can be vertical or horizontal…. I just heard you mention a weld positioner!
Yes sir, it’s definitely on the tool wish list. I’ve been wanting a weld position for a while, just haven’t been able to invest in one quite yet. Hoping this year. Thanks for the suggestion, and thanks for watching!
Please don't change a thing I really do enjoy the way you explain things and why they are the way they are and this video I have learned a lot and thank you
Thank you sir, I appreciate that.
I will continue making videos In the same format. Thanks for watching!
Looks really good. I’m not a tig welder. The purging process you used on the root pass was this because of stainless or the tig welding process? What kind of gas did you use?
The purging process was required because it was stainless steel. If you don’t the Stainless will “sugar” where contaminants are introduced into the weld. The gas you use for purging is Argon. Thanks for watching!
Bon Boulo😆😆👍👍
Nice work Patriot brother . :)
@@johnjay5143 Thank you for watching!
👊🏻🇺🇸
Nice video new here I do alot of similar work at my work a lot of type 316 stainless pipe and flange work . I don’t get the socket flanges so I usually have to weld inside and out. And reducers ours are offset I wish they were like yours lol easier to 2 hole. It’s always interesting to see how other people go about set up nice job. Not sure if you heard of it check out kapton tape it’s a high temp tape good for purging and you can get it with no adhesive in the middle of the tape to help with residue sticking not too expensive. Just subscribed 👍
Thanks, I checked out your channel and subscribed as well. Looks like we definitely do a lot of similar work. I’ll check out the kapton tape. Thanks for the suggestion, and thanks for watching!
@@Freedomfabrication777 thanks I’m new ish to the TH-cam video making mostly do Instagram stuff for fun but getting into this TH-cam video making and kinda having fun with it lots of work especially editing for me lol. Good work with your video though I’ll have to check out more . That was a good quality video too
Cool video. A trick I picked up on the yootoobs, get some 3/4" copper pipe, cut them in short lengths, split them lengthwise, flatten them out, then wrap them around the jaws of the lathe chuck. The copper will bite into the threads of the half nipple and won't screw them up but will let you tighten the jaws.
Great suggestion. I’ll give that a try. I’ve been thinking about tapping the jaws in my lathe and adding some copper soft jaws. Have you ever done that?
@@Freedomfabrication777 I haven't. But is on my to-do list.
@@MyLilMule You and me both. That one could be tricky.
@@Freedomfabrication777 Just need a good carbide end mill to get past the hardened layer. Then drill and tap. I don't think it will be too bad. Too many other things going on to worry about it right now.
Man I feel like I was at work watching this one. The last job I was on was a completely all stainless job. I don't have tig certs so I was just a fitter but I fit for a lot of the guys and girl on the job. Stainless ain't no joke, I enjoy fitting it with the pulling aspects, kept me on my toes 😂
Stainless is tuff. The pulling aspect can definitely keep you guessing. I do enjoy the challenge of it though. Probably wasn’t all that fun to watch if you felt like you were at work. Lol. Sorry about that.
Nice to see how other people go about fitting so i enjoyed @Freedomfabrication777
And you were also kind enough to show those tungsten grinds when necessary. I just happen to need regrinds ALOT more often... I think my filler wire defy gravity and jumps onto the tungsten like it's posesed. 😅
You have a very nice shop setup.
Thanks! It’s a work in progress. Thanks for watching!
Is that jig on the rotary tool home made, or is it an accessory available from Milly, or aftermarket?
It’s an aftermarket tungsten grinder sold with the Milwaukee rotary tool. I forget the brand at the moment, but I’m sure google will help you find it. Thanks for watching!
I looked last night. It’s a “sharpie” brand grinder. You can get them at either arc-zone.com or Amazon.
@@Freedomfabrication777 cool thanks👍
Dynasty and skills for the win brotha!
Thanks man, I’m a work in progress. Just ask my wife! 😂
Same with me brotha @@Freedomfabrication777 🤣
Aloha from Seattle! I love your videos! I learn a lot of stuff from you and other fabrication guys on TH-cam. Safety issues are fascinating to me, for obvious reasons, so my upcoming comment here about using your lathe with the tie strings from your hoodie being loose, is for newbies like me noticing this and being aware, than a comment aimed at you for spite. The beauty of your videos go beyond what you may think. Keep at it! Good work! - Joe 😊🤙
Joe from Seattle, thanks for feedback on the videos. I’m always trying to improve the videos for the viewers. Hopefully that reflects in the finished product. As far as the hoodie strings go, it’s better safe than sorry. I appreciate the advice, and I will pay more attention to that in the future. Thanks for watching!
Another great video! Your videos have inspired me to get into a weld shop that does similar work to you (anything/everything) as a part time gig on top of my full time stainless tig job! Excited to start learning different weld processes and fabrication. Thanks again for the awesome content man.
Thank you, that means a lot. It seems surreal to hear someone say that I have inspired them to get more involved in welding. I’m glad to hear that you are. The world needs more talented, hard working people to build, and fix things. If you ever have any questions, feel free to reach out. Not sure I’ll have the right answer, but glad to help you continue to better yourself. Thanks for sharing that, it made my day, and thanks for watching!
Nice work! I loved all the tips! The camera/audio quality was noticeably better!
Thanks brother, glad to hear it. Thanks for watching!
Nice work. What is the brand electrode sharpener?
The tungsten Sharpener is a “Sharpie” brand. You can get them at arc-zone.com or Amazon. com And I love mine. Thanks for watching!
@Freedomfabrication777 I'm wondering why I cldnt comment, also I had to subscribe to ur channel again, also what was the pressure while purging, coming from tank
@@charlesmecum5009 I’m not sure why some people randomly get unsubscribed from the channel. You’re not the first person I’ve heard of having that same problem. The purge gas pressure was about 7 cfm.
Nice, that new Miller shure makes for a nice finished product. I know your work is nice regardless of the machine. 👌
Thank you, and yes, that machine is the Cadillac of the TIG welding world IMO. Thanks for watching!
I enjoy the shop modifications. Another great video per usual! Already looking forward to the next project 👊
Thanks brother, I appreciate that. I’ll keep the shop mods coming then. Thanks as always for watching.
As someone who’s been trying to get into welding for pipe fitting this video was very informative and a great breakdown for others who don’t know how to fit stainless along with welders learning the pull ect. Great video man
Thanks, Glad to hear it. The trade needs good hands. I’m happy to answer any questions that I can. Thanks for watching!
A+
Coming from you, that’s saying a lot! Thanks brother.
It doesn't count unless we get to see the root!
Kidding, great video as always!
I hope you could see it good enough to judge. Lol. Thanks for watching!
running that gravity band saw to cut stainless, does it not impregnate carbon into the nipple?
I haven’t had an issue with it. Plus I machine the surface material off with the lathe, so that should eliminate any chance of contamination as well.
For the record 316 stainless already has a very small amount of carbon properties within it as most stainless steels do. People obsess over this carbon contamination way more than necessary. As long as you keep it clean as you go, it will be fine. I would be way more concerned over the fact that he didn't allow a 1/6th to 3/32" gap between the reducer and the flange to allow for weld shrinkage that puts unnecessary stress on the joint and can lead to cracks.
