Thank you for the reply. Agreed, this is a serious business, everyone needs to treat it as though their family is the person depending on these systems. Appreciate your comments and concerns.

Great observation and comments. I fully agree and from your comments, it sounds like you are brazing correctly. Thank you for watching and providing feedback. Please check out our NITC updated Medical Gas Brazing Video at th-cam.com/video/aPnRrEuVvlQ/w-d-xo.html and additional braze test information on our website at www.nationalitc.com under "Medical Gas Brazing Processes"

Heat, under the right circumstances, can and will rise

Hello Mike, we have developed a newer video and it is available on TH-cam and the National ITC website at th-cam.com/video/aPnRrEuVvlQ/w-d-xo.html Please check it out. It does show the penetration after sectioning as well as a lot of other up to date useful information regarding compliant Medical Gas brazing. Thanks for the comment. dj@nationalitc.com

Thanks for watching and posting a comment.

You made good money doing medgas? Where you union? What state are you in

I know it's been a year since this comment but I think it's the most helpful, by far. I just left the field to start up a High School vocational program within Local 166. It's been great and I'm trying to put a little bit of everything in front of these high schoolers so they can decide which side of the trades is for them. I really appreciate your explanation on this process. I wasn't doing enough hospital work and let my cert drop a few years ago. I was looking up videos as a refresher course. I just want the high schoolers to see the process for a day or two and move on. I'll be utilizing your details within my conversation. I like to teach the overkill style of brazing MedGas uses prior to simple refrigeration brazing because it's easier to water your training down a little for something not so critical but it's hard to amp up the details that medgas requires. I learned medgas first so when I did refrigeration everyone else would do a swipe/cap method and move on while I would push some filler into it prior to a cap. Good stuff. Thank you again from Local 166

@@cdays01 wow! Thanks for the positive feedback. I'm happy I was able to help a brother out. Good luck with your endeavors there. Is it something the UA is sponsoring or endorsing? These days, it's only the rich schools that still offer any kind of vocational training like this, where the kids are least likely to need to know. I think we share some of the same philosophy when it comes to brazing. I load the cup from 5 to 11 o'clock, going clockwise, then from 7 to 1 counterclockwise (I don't like to get to 12 before I know the rest of the cup is full, in case there's a cascade effect that could cause holidays), then 10:30ish to 1:30ish, then turn the torch down a little for the cap. I like to heat the rod about 2 or 3 inches from the tip so i can give it about a 45° bend in it. That way, no matter what position you're approaching from, you'll always be able to get the right angle on it. ..and I use 100% of every rod. Melting 2 rods together end to end doesn't have to be a big production. You can do it on your ladder. Hold the tips of the rods together like chopsticks. Melt them together in that position. Then, while they're still hot, straighten them out right away. I don't mean to be preachy. I'm just thinking about things that might help. I learned how to braze back in jr high school, in the 70s (the late 70's, a'hem.. I'm not that old.. lol), then onto oxy acet welding and i still do a bit of it here at home. Did you know you can braze with copper wire? Use boric acid for flux. Termite poison is a great source of boric acid. Heat the wire briefly then dip it into the boric acid. ..and you can braze stainless steel if you use this kind of black brazing flux. Its really nasty stuff. Use in ventilated space. ..very well ventilated and avoid skin contact. Its very irritating. ..my point is that maybe you can save a few bucks by getting the kids acclaimed to using a torch by first brazing with 14 or 12 gage copper wire on some carbon steel coupons.. idk Thanks again for the positive feedback brother

@@jdog4534​​⁠ I’m going to try that brazing with wire out (outside the solder braze lab). We started a weld program about 3 years ago with high schoolers and it was very successful. So, they approached me with the idea to make our own general trades program. It’s been incredible. The junior can move right into a paid intern role their senior year and our contractors are eating it up. Out of my 20 students (40 next year) 3 were hired as apprentices and 13 were hired as interns for next year. I’m a year long screen process basically. The kids get great experience either way. Even if they decided it’s not for them they’ll be making 40% of journeyman wages while going to school. The community loves it, our members are finally sold on it, and the kids are gaining more than they ever could have from an in school program. Really great stuff going on at Local 166. Proud to be a part of it. Thanks again for the information. We don’t get to leave a lot in this world but passing on knowledge is a major gift we often take for granted.

@@jdog4534seems like you are a goldmine of plumber wisdom, im 20 years old i live in northern kentucky, i just 4 weeks ago got my journeys man license and now i am thankful for the opportunity to be taking a medgas certification course. Just today i brazed for the first time in preparation for my course coming up in 12 days. I at first had no idea what to expect but im glad i stumbled across this video it is extremely informative and even better your multiple comments. Thank you for taking time out of ur day to inform others and share your knowledge this is some 1 in a million advice youd only get by finding the perfect mentor, if it wasnt for the internet i would of never got to read this comment. Thanks again

The practical portion of the ASSE 6010 may be performed at the training provider’s facility or any contractor’s or manufacture’s facility that can provide a safe, well lit, appropriately equipped location for testing. An essential requirement is the brazer performance qualification test must be supervised by a designated company representative meeting the requirements of ASME BPV Code, Section IX, Part GC. The company is required to own a qualified braze procedure, similar or exact to the procedure being used for the brazer performance qualification test. A Brazer Qualification Record (BQR15) must be completed by the Designated Company Representative for each Brazer participating in the test session. The completed BQR must be submitted to NITC with the properly prepared braze test coupons. If additional information is required, please send an email to: brazing@nationalitc.com , thank you for your inquiry.

@@djbnola1 thank you for your quick response. I appreciate it. I'll have to look for a facility that can provide the 32 hour class and the practical.

iliketakingshowers you are very welcome. Please send me an email and we can continue the conversation. Thanks again.

Congratulations David on obtaining your Medical Gas 6010 Installer Certification. Please check our updated MedGas Braze Video at th-cam.com/video/aPnRrEuVvlQ/w-d-xo.html .

Right on brutha! UA all the way!

Good deal 👍

What is the difference between a cert and license in terms of medgas?

@@manillagorilla1986the certification is what is required by the code, the license is usually what is required by the state or authority having jurisdiction (AHJ). Most states accept the Certification as a prerequisite to obtain the license. Not all states require a license but if a project is being installed to the NFPA 99, then the Installer must have a current ASSE 6010 Certification. Hope that makes sense. Thanks for viewing the video.

James Piworski, you are probably correct The video was shot at one of the A&Js back in the 90s It is a bit dated, but still relevant to the industry. Please check out the updated braze video on the NITC website www.nationalitc.com Thanks for the comments

I somewhat disagree. I mean that rosebud is the size I use when brazing 6"Ø. I would go down a size or 2 on the rosebud. But I usually braze with an almost neutral flame and heat until everything is bright orange then jam that rod in so I feel constant contact with the edge of the coupling. From 7 to 2 o'clock, then from 5 to 10 o'clock, then 3 to 11 then 9 to 1. Knock off that dingleberry then cap it. If no dingleberry then joint is starving. There won't be any carbon inside the pipe. It doesn't matter what the outside looks like. Not for the test. If you're putting up show pipe, then I would agree to take the time to make it look good but not at the cost of having holidays in the system that can harbor germs and whatnot. On big hospital or laboratory jobs where the med gas crew is 15 to 20 hands, it's been my experience that there are always 4 to 6 of them who have no business holding a torch but their work passes the pressure tests on jobs because you could forego the whole 100% full part and just cap it and it will hold 150 to 300 psi.

Yes, please check out the updated video for Medical Gas Brazing that was produced in 2015. th-cam.com/video/aPnRrEuVvlQ/w-d-xo.html There is also a "step by step medical gas braze instructions" presentation available at www.nationalitc.com that has detailed illustrations. Thank you for asking. DJ

Very good observation. Please check out the updated 2015 video at th-cam.com/video/aPnRrEuVvlQ/w-d-xo.html Thank you for viewing. DJ

Thank you for viewing the video and for your comments. Yes, this video was made back when the Medical Gas Piping Industry was getting started. It is dated and it shows. However, it is still a great demonstration video, which is why we posted it. All of the items you address may be found in the NFPA99 and ASME BPV Section IX Codes, which are applicable to Medical Gas System Piping brazing. We have recently published a new updated video which addresses all of items you commented on, along with additional information on what to look for during inspection. The video and additional information may be found on the National ITC Corporation website at www.nationalitc.com. Thank you again for your comments and we hope you enjoyed the video.

@TCudahey, yes you are correct. Bcup filler wire is used when brazing copper to copper medical gas piping. Bag with flux is used when brazing dissimilar metals such as copper to bronze or brass. But even so this was a very instructional video on brazing a medical gas coupon for the asse 6010 installer certification.

Lol you seem like you know why we didn't see the bend test performed. He had way too much rod left for there to be enough rod to fill both cups. I doubt he even got full penetration at the 6 o'clock. You have to jam it in there hard so that you feel the contact of the rod against the edge of that coupling no matter how fast its melting. We always test with that liquidy 5% crap but use the 15% honey stuff on the job. I remember when the 15% was $30 a pound. Last time I checked, the 5% was $45 a pound and the 0% was $30 a pound. The 15% was around $150 a pound 😳

Hi Sherwood, thanks for checking out the video. This one dates back to the early to mid nineties, as you can tell from the side burns and paisley print shirt. Please check out the updated version on the National ITC website. Www.nationalitc.com DJ
