HOW TO Back Purge Stainless Steel Tube and Schedule Pipe + TIPS

Today we will be talking about HOW TO Back Purge stainless tube and pipe + TIPS. We will be using Silicon purge plugs from @Tigaesthetics and I will be going over the essentials needed to make a good quality Back purge. We will be showing examples of Carbide Precipitation as well as good atmosphere free purges on stainless steel tube and pipe. Titanium is basically the same method but you really don't want to see any oxidation on It like you'll see on stainless steel. Titanium is much more sensitive to complete changes in the materials structure when you don't back purge correctly. In the video I will post a link to another video in this series called "How to properly prep stainless tube".. You would be surprised at how many people in the industry are not back purging their products and that is constantly resulting in Cracking and constant repair. Pair that with a race car or something that needs to perform and the two just don't go together.. GOOD QUALITY WELDS are key to any product.
Don't be discouraged if you are having trouble getting a good Back Purge.. Just follow these steps and try your best. If you have any questions regarding welding and fabrication I'm 100% open to answering all of them if you message me on my instagram account attached below..
Be sure to check out my last video on HOW TO PREP STAINLESS STEEL TUBE because we will be going in order in this series from Material Prep to Back purging, Fit up and Pie cut exhausts.. We are going to cover the basics on this topic to make sure that each and every one of you are up to speed and feeling comfortable during the Welding and fabrication process of exhausts and stainless steel.

Running a water line in a beverage facility now, this video answered my question perfectly!

[@hourglassingenuity103]

That’s fantastic!

[@marklowe7431]

I'm stunned at the quality in these videos both the knowledge and the teaching ability.

[@alexweeks4203]

Excellent video, Brad! As usual with your videos, I appreciate the quality of the video and the accuracy of the information outlined in the video. It’s nice to hear standard terms for things like carbide precipitation, and pointing out that “sugaring” is more or less the slang equivalent. It makes it easier to know exactly what you mean.

[@ndav8r]

I TIG weld vintage SS auto trim, and at .011" thin, back purging is a must! I also weld in Aerospace which I back purge almost everything there...can't get by any certified tests without it!

[@dhanwatiesukhai2524]

Thanks Brad ! , very much appreciated that you're making these videos. I'm tremendously grateful for the time you're putting into the explanations for various aspects of different processes. Im Andrew from NYC.

Hey Andrew! Thank you, I appreciate you for watching and thanks for commenting! Absolutely, I enjoy trying to explain things and I’m more than happy to help anywhere I can! Have a great day.

[@garybendickson7262]

Well Done I like how you explain out fit up & purge I work in the food industry & are Stainless welds whether 304 or 316 have to be perfect so I 100% agree that everything has to be as close to perfect as can be . I see from your shop you must do a lot of Turbo conversions that sure would be fun in my books . I like your V band connector your systems must be first class & beautiful to look at would love to see some under hood shots of cars you have done & what the system looks like after the Turbo. Wow really nice !

[@sethstrohm7877]

Brad, you have so much knowledge. I recently stumbled across your channel a few months ago, because im taking my welding to the next level. I was wondering why you stopped making videos? Did you start a new channel? The welding community could very much benefit from your experience

what amperage are you running at? cup size? and purge cfh with them slick plugs you got. and cfh for the torch? good looking welds, looks like all your parts sitting behind you have all the same type of craftmanship in them too

[@fabricationsolutions7067]

Awesome

[@powerneedy]

Great video! I do have a quick question though, where can I find the scotch brite for the bench grinder?

[@fdrfab]

3M sells them.

[@viniciuszamith]

How can I purge straight plates, such as a square sink for example?.

[@adamlloyd2688]

Awesome video as always, what sort of amp are you running?

[@hourglassingenuity103]

Thanks Adam! I run 65 amps on the machine and typically use 80-85% of the pedal.. I have the extra amperage there to utilize really penetrating on restarts and widening the toe width quickly to get going again and avoiding unnecessary concentrated heat input by hanging around too long. 👊🏻

What if you can fuse with no burn through ? Serious question, thank you.

Ever use solar flux?

I have seen it used but my background is in automotive fab and Aerospace and I would never be in the situation to absolutely have to use that method. Great alternative in a pinch though. 👍🏻

[@ckgrant5373]

Where does @tigasethetics sell his products?

[@hourglassingenuity103]

I just put the link in the description. My apologies. Here is the link to his site.. www.tigaesthetics.com/shop

[@YszapHun]

9:40 I do not suggest using any tape, whether it's masking tape or PET tape because all of them leave some kind of glue residue, and when a pipe is tacked together it's impossible to remove all of the tape residue without getting some of that inside the joint, between the two metals.

[@hourglassingenuity103]

Whether it is Tube or pipe.. Powder coating tape leaves no residue.. that’s why I use it... I appreciate your input and I can promise you my recommendation works and works well. I have welded plenty of aerospace parts using this method that have very strict requirements and I have also used this same method to weld many many titanium and stainless tube assemblies. Have a great weekend!

[@YszapHun]

@@hourglassingenuity103 Just did a check as to what powder coating tape means for you, but it's the same PET tape of what I thought it was. I believe in your experience, if you say that it leaves no residue. I hadn't yet done any weld job that needed X-ray but I would imagine that it would have left residue (I am extremely meticulous about cleanliness). I really like that you read and answer all relevant comments, you're a cool guy.

[@hourglassingenuity103]

YszapHun I try and read and answer every comment if I can! I really appreciate your opinion on the topic and I enjoy reading your comments because you seem very educated. I have never had any trouble with residue but I have had massive amounts of trouble with using scotch brite on a tacked joint and introducing fibers into the joint and have contamination issues that way. Either way, so many ways to do something! Thank you for your time and engagement. 🙌🏻

[@brandonpejsa]

YszapHun don’t know if PET tape is the same as kapton tape. But kapton tape has been the go to for many. And as brad said, it doesn’t leave residue.

[@bradvincet1848]

You would be appalled if you saw some of the shit that people do in the building trades. "Back purge? Nah, that takes to long besides it's not really necessary for what we're doing." I hear that all the time, and we're a skilled trade.

[@MK_Jynx]

Came for purging tips but got distracted when I saw the s13

[@seansmith4440]

Why is having a diffuser on the purge so important? Argon is heavier than oxygen. Just like the water example, filling up a glass is going to be the same if the water is diffused or not. It's still going to remove the air exactly the same as it fills up from the bottom.

Basically junk? Very harsh judgement when not stating for which application it is considered junk part. 99% post turbo exhaust parts are not purged and I have made many exhausts with or without purge. Not a single cracking after years of use. When in contact with liquid, intake, or very high temperatures all 100% purged when using austenitic steel and high nickel alloys.

[@hourglassingenuity103]

Not harsh at all. Anything that isn’t purged is low quality. Sorry. 🤷🏻‍♂️. I don’t know who this 99% of post turbo exhaust parts that isn’t being purged is.. but that’s False info. I literally don’t know anyone who doesn’t purge exhaust parts in this industry.. and I know a lot of people in it. Sorry to hurt your feelings.. have a good day.
