Welded alot of thin wall 316l tubing using this method. Alot of in-position free hand, but since you’re not using filler its easier to prop. Such a smooth and pleasant process when you get the hang of it. Great vid Matt, would love to see more of you on the channel!
Something I do everyday! Glad to see you all showing people what's up with it. There is more to it than what some people think and like any form of welding can be refined into an artform.
"the devils eye" ---> excellent explained . I just started tig welding on thin pipe and your explanation about the devils eye helped me a lot since I had problems with the thin pipe . I tried it today and it worked excellent . thank you very very much for your video and help !! grtz from holland .
Excellent demo & explanation. Really liked this lads delivery style. I’ve tried this stuff & struggle. Approaching 60 now & just not supple enough anymore to go top to bottom in one smooth motion. Thanks for the great video though
Last company I worked for, we did a lot of this type of autogenous welding on tubing known as 8LMP. Same type of material and process, and just like this man in the video explained not much room for error.
maybe you can already do it but if not you are still young enough to master going all the way around without breaking the arc. 6g, start at 4 o'clock down to 6 then uo to 10 o'clock switch hands no break in arc past 12 switch back to right hand around 2 o'clock then continue back down to 4:30, Helmans Mayo-Best Foods, and corporate Budwieser, have sample boards with my welds. i am now 67 long retired just want to pass something on, you are great!
It can vary but most of the time with sanitary you're not going to have a defect that isn't a cut out. Typically grinders aren't allowed as the dust can cause contamination along with embedding particles into the tubing. Remember that this stuff is either putting something in or on someone's body as the end product so contamination on any level is unacceptable.
Great video , can you guys explain how to finish or pull of using the lift tig method without causing any craters ? Or how to terminate the arc with proper gas coverage ? @WeldTube
I can try If you don't have a foot peddle then the best thing to do is once you tie in to the other half of the weld is to begin walking it fast and narrow gradually tilt your torch back starting to long arc until the arc goes out. Then let your post flow sit on top of the end of the weld.
if you do have a foot pedal then it's the same process you just don't long arc it off instead just gradually let off of the foot peddle until the arc breaks.
@@williamhunter277 thanks for the reply I appreciate the help. I’m a welder, stick and mig but tig is something I’m just getting into, the machine I have is only lift tig capable so no foot pedal. So just to be clear, long arc it till the arc terminates and let the gas flow over the weld ?
@@robertogutierrez3593 We all start somewhere man no one was born an expert on this it's our job to pass on as much knowledge as possible. But your doing that while walking it down to a fine point. The finer the point the less likely it is to fisheye or a pinhole.
i work at dairy and farmaceutical plants and that weld will not pass there. It's too dirty in heat affected zone, it should be white like snow on inside
Great weld technique, could've done with a bit less oxygen in the purge. That inside tint wouldn't be acceptable in pharmaceutical. See: ASME BPE color chart.
I do this sort of welding everyday too but why do you Americans not use slope out? Can't see the point in just snapping out as surely your gonna get a pin hole now and then!?!?
About 34 years ago I worked for a company building milk tankers for AMPI. There's nothing quite like a USDA inspection. Every weld inside those tanks had to be finished completely smooth, where you couldn't even tell there was even a weld there. We used flapper wheels on the end of a drill to sand the inside welds down to tank level and then we'd polish them. The manhole in the top and the ports on the back had to be welded the same way. We also ran beads on every joint and seam on the outside too but we just used a MIG for those because they didn't have to be sanitary. It took about two weeks to finish one working with two men crews if I remember correctly and that includes insulation, skin. running gear and fifth wheel mounted and ready to roll down the road. I'm a rig welder too and I only took that job when the oil field collapsed in 1986 and it held me over until I could put my rig back to work.
Food grade welding is so clean it is satisfying with the end result. I've seen 10's of thousands of feet of stainless food grade pipe work and the couple of dairy plants I used to work at. So clean.
He really went into detail and for me he was easy to understand nothing negative against anyone else they all do great i might have a more difficult time understanding people when learning but he was definitely a very good teacher thanks guys
I’m the same way man idk if I’m a dumbass sometimes or people just suck at explaining things, I like to give people the benefit of the doubt and just consider myself an idiot but then there’s dudes like him who make it clear as day for me on the first shot.
Super helpful as an engineer designing some of these sanitary tube applications to see what the weld process should look like and things to look out for to make the design easier to weld and a better end product. The video is a great resource when you can't go bug your welders in the shop for a demo!
I use a #4 on a stubby gas lens with a 1/16" tungsten stick out. I also run 42 amps on 2". 5 cfh on purge and 25 cfh on a ck swivel head rig. Important to note that your purge can be ruined if the pipe is colder than the ambient air temp. Condensation will accumulate on the pipe i.d.
You just pointed out something i never thought about.... condensation inside the pipe. Could explain alot of defaults i had in some of my full pen welds. Thnx for that, i will consider this next time.
So stoked this was covered I live a Dairy Town and this is right up the alley of what I wanted to see thanks hopefully we see more of the Sanitary welding thanks 🙏
A coworker just sent me this excellent video. I thought this could only be done at an acceptable level with orbital equipment. Edges still need to be faced however. Great technique Matt! Thanks for sharing. We put this into practice immediately with similar results. :)
Excellent demonstration! Working for an FDA facility producing soaps, lotions, and hand sanitizers, I weld sanitary all. the. time. This was very informative and answered a couple of lingering questions I've had about how to perfect my craft.
Hey man I’m a certified welder for pharmaceutical tubing and I run piping where even dust in the tube I’m unacceptable. If you want any tips on sanitary piping I’m sure I can give you a little bit of everything that you’d want to know.
@@richardmaschack2150 I’m a beginner welder but considering it as a career. I assume that this type of welding is pretty hard versus other tig pipe because of the lack of room for contamination?
Hey dude sanitary means no need filler wire or any metal to supply just melt it two sides or both sides always take a look on devils eye thats the word i learned from you bro,good info keep it up,im also a welder gtaw/smaw combi and gtaw/fcaw combi pipe welder,never been welding that kind of pipe sanitary welding,i want to experience that also that was interesting.
Nice vid. The only sort of thing missing for me was where to purge from and to. I was under the impression run the purge from low spot out of a higher spot. Argon is heavier than oxygen. Would love a run through on how to do long lengths of continuous pipe.
I am currently a mechanic at Tropicana and sanitary welding is the only thing holding me back from getting my full pay, and you made this so much more simpler to understand and the one thing killing me was learning these tips.
I'm interested to know why your purged from the top of the spool and not the bottom ? I was always taught to treat the argon like water filling a bucket , inlet at the lowest point and vent at the highest to help evacuate all the atmosphere more smoothly. Good video thanks for the content. Best regards Canada
Matt, Thanks for getting back. The HH 300 is a bit heavy and I slip on the smooth stainless. I have seen where some guys grind a groove or slot in their gas cup. Is this helpful. Thanks again for a very professional presentation . Tim
A few things to remember on purging tube. Not all flow meters are alike and your readings on your flow meter have a relationship with your outlet orifice. Meaning the smaller the outlet orifice the lower the flow to maintain good pressure. Letting the purge gas blow in your ear and weld profile appearance will educate you on your flow meter settings. Also it’s best to purge from a low point if possible. Welding joints of tube together is more sensitive to hi and low pressure than welding a fitting on a piece of tube and generally welding tube to fitting or fitting to fitting takes a couple more amps than tube to tube. Also pay attention to how far your plugs are from your weld, burning them up if bad form. This gentleman is using heat tape for his outlet dam which is common with sanitary guys but sometimes expensive depending on where you find it. I’ll often use good heavy duty aluminum foil, both work fine if your weld would be to close to your outlet plug. Now y’all go get to work I’m retiring in a few more years lol.

Always great vids but idk if anyone else caught it just found it funny that on the 305 he has miller killer but yet running a miller dynasty haha 😄
I have a dynasty 210. Fuckin love it
Saludos desde Puerto Rico, los soldadores de aqui queremos un video similar pero en español, gracias soy fiel seguidor..
You didn’t show tacking the other piece of pipe. I was just curious on how you did that.
beautiful work!!
Belo trabalho 🇧🇷
Nice work man! You just got an IG follower.
Thanks Cory! 👊🏻💯
Great info, thanks!
Any reason why you don't have the pipe on rollers so you can spin the pipe while your running a bead?
That would be too easy! Lol, trying to make it like welding in the rack, believe me I roll out as much as I can, but not always an option.
You are awesome thanks for the info
Does it make the length of the tube shorter at all when fusing with the base metal only?
Top notch aloy metals welder 💪
Thanks brother! 🙏🏻
How do you get rid of the fish eye on your stops? With the pedal you can ease off and it’s not a problem but it’s a problem for me on the lift arc.
What do you do with defects are you allowed to grind them out on sanitary pipe or will the contaminate?
Not familiar with this, but i have heard about "Use a file ONLY" on sanitary tubing tests
Where I’ve done work it’s always a cut out repair
It can vary but most of the time with sanitary you're not going to have a defect that isn't a cut out. Typically grinders aren't allowed as the dust can cause contamination along with embedding particles into the tubing. Remember that this stuff is either putting something in or on someone's body as the end product so contamination on any level is unacceptable.
Great video,when I learned ,what you call the devil's eye I was told it's the man in the boat..
Superb!!
Nitido soldadura sanitaria I'm a welder too from N.Y long island I work do some of that thank you for the video.
What's the yellow material on the end? Celophane?
Is there a specific tungsten that is required for food grade welding? sorry. noob in school over here
I use 2% Lanthanated for pretty much everything
This helped me!
Impressive
Totally awesome
I weld same pipes in Norway from time to time but inspector say i must use 1 mm filler becouse of the steamer preshure when they clean the pipes.
I realize there are probably several factors to consider, but how thick of 304 can you go before you need to bring in a filler?
You can do sanitary welds by hand? 😐 every electro polished tube I’ve ever seen welded was orbital welded
Absolutely! Orbital welding is great but not very common in plant shut downs
Muy bueno 👌👌👌,cual es el mejor tungsteno para inoxidable?
How wide should your puddle be at the end is it like 1/8 wide
Great weld anyone know what helmet he was using ?
where can the locals buy the clamps to cut this pipe clean with a porta band that's how we did it in the day but wasn't perfect cut
Why not use the high frequency of the miller?
Well, let's see what the South Coast has for u- OH SHIT THATS MY WELDING TEACHER!

Thanks man learn something new
i work at dairy and farmaceutical plants and that weld will not pass there. It's too dirty in heat affected zone, it should be white like snow on inside
What was the lens called sounds cool 😎
What's the name on that purge kit?
Purge kit.
Nice weld,good explaining but too much colour inside.
No chance to pickle or brush.
Great weld technique, could've done with a bit less oxygen in the purge. That inside tint wouldn't be acceptable in pharmaceutical. See: ASME BPE color chart.
Sanitary welds....cool story bro
This is all I do. All food grade stuff
Hey brother could be get some more pipefitter videos!! That first was was 💯💯💯

Not too wide and no color inside...no undercut....wiggle away
Autogenous=Fusing
The more you know🦚🌈
Took too long to get to the welding.
$$$$.....money sir. money
I do this sort of welding everyday too but why do you Americans not use slope out? Can't see the point in just snapping out as surely your gonna get a pin hole now and then!?!?
Using that big of a jumbo cup/torch set up is completely unnecessary and a huge waste of argon

One important thing you didn’t talk about was the size of the purge hole in your heat tape.
One thing you can do to check that is to lick your knuckle and put it infront of the hole, if it feels cold then its enough purge flow.
