Titanium is actually pretty easy to weld. But following procedure is super important.
Argon shield is way more important than more commonly welded metals like carbon, stainless, and aluminum.
Shielding the back side of the puddle is absolutely necessary.
Argon purity is more important as well.
What works on stainless steel will not necessarily yield acceptable results on tig welding titanium.
In this video, I welded a simple butt joint in 1G. But I still ran into a few issues with my shielding gas.
In future videos, I will cover things like using a purge meter, welding inside a chamber, using trailing shields , and more.

you keep knocking them out of the park; great vid.
This Old Tony, I see you knocking it out of the park too!
As a former quality testing chemist for a gas supply company, I can tell you that they only check for oxygen in "industrial" grade Argon. Move up to 4.8 grade and it's oxygen and moisture. You have to get up to 5.0 or even 5.5 grade to start testing for things like Nitrogen or hydrocarbon impurities. Sometimes industrial grades are filled alongside 5.0 grade in the K and T size (250 and 330CF Argon) cylinders (with the lot tested to that high spec), but your smaller customer owned cylinders will almost always be filled as just industrial, which would explain your experience with the different sizes.
BattleChemist thanks for the Good information
Happy to be a resource for gas knowledge. I spent 7 years there testing up to 5.5 grade spec and AWS specs (plus medical, food, and beverage specs) and was a Quality Assurance Reviewer (signed off to release product to the public) for 5 of those years before moving on to a different career. Not claiming to be an expert, but I've learned so much from this channel I like to give back where I can. 😊
I remember getting quite a few cylinders of industrial argon marked "bad gas" by the customer to find there was around 0.5-1% nitrogen in it from nitrogen tanks being converted to argon (same CGA 580 valve) and not vacuum-purge-vacuum-fill process like you would for a spec gas. But that was "acceptable" due to not testing for it... though, if converting, the tank was 'supposed' to be purged. 😒🤐
What instrumentation did you use for testing the gas? I'm a chemist as well but spent most of my time in grad school working on a STM and AFM and when I finally got into industry I worked on the wet side and never had a chance to test any gases. I enjoy working with instrumentation. Almost had a job at a smoke lab but a stupid recruiter messed it up for me. Oh well, place was awesome as pretty much everything was brand new, which was a far cry from the wet lab were most of the equipment was built in the 80's.
@@Parents_of_Twins It depended on what impurities or percentages we were trying to test. For Total HydroCarbons (THC) we used a flame ionization detector. For trace oxygen, it was electrochemical with potassium hydroxide (KOH) solution in the instrument. For oxygen percentage, it was paramagnetic sensors. For carbon dioxide purity, we used ~30% KOH solution wet chemical that absorbed all the CO2 and the leftover was 'impurity'. For trace CO2 percentage and trace carbon monoxide, we used non-dispersion infrared (NDIR). For trace water, we used electrochemical where an oxide layer on a substrate increased current as water reacted with it. For just about everything else, we used GC-TCD (gas chromatography-thermal conductivity detector) for percent levels and GC-HID (gas chromatography-helium ionization detector) for ppm levels.
I was just going to ask about the grade of argon gas.
I NEVER rented one before and I was making a lot of assumptions.
nicely executed on how to tackle titanium. this does give me a way better understanding on how to approach this material. Been welding stainless. inconel and aluminum for 13 years now and cannot wait to add titanium to the resume. Keep the weld craft alive everyone. Stay safe.
Thanks for being my go-to for all the hidden tips in the industry 🤙
I always enjoy your welding videos. I have been a welder for 15 years and I always have to learn and I am very informative thanks for sharing.
When we welded titanium we always did it in a "glove box" where all O2 was purged out with argon...welding little titanium grommets for the SR71!
JoJo Mama good point. some parts require welding in a chamber. Some are more efficiently done in a chamber. But there are also plenty of applications where a back purge along with a trailing shield or large cup can get the job done
i've seen the welds on the mighty J58
man those welds look like garbage.
acceptable for the 60s i guess.
3rd Gen Guy ... don't know what '60s has to do with anything,they had destructive and non-destructive testing back then.In my experience a good weld is usually a pretty weld but then again I don't know what you were actually looking at
3rd Gen Guy.....again,when I hear someone say "garbage" especially when it comes to aircraft it really makes me wonder if this person has any idea what he's talking about
I have been welding for fun since I was a kid. I would love to learn to weld Titanium, but after seeing this video, I realize that basically, I know nothing. It seems like a lot to learn before I would even try.
Another great video. This is way beyond any welding I will ever do but it’s super interesting to see the techniques to weld exotic metals. Your the best Jody, keep the videos coming
I've never watched a video from this channel that I haven't learned something from. I took ag mechanics for two yrs in high school when we welded in that class all they did was hand us a mig gun or a stinger and said weld a bead never explained what we were doing wrong or teach how to do any settings. I have always wanted to weld I want to go to welding school still trying to find a good one near me anyways what I'm trying to say is I have learned more from your videos in a yr of watching them than I did in those 2 yrs of high school keep up the great work Jody and thank you
Awesome video sir. I made a series of videos a few months ago showing some issues I was having with stainless, just couldn't quite figure it out. As it turned out, it was the argon. Swapped out the bottle, and solved the issue. I have noticed now since running several more bottles through on a large project i was doing, that the last 10-20% of the bottle it really started to weld like crap, welds grey looking, etc... so good to see you cover this
Ramsey Customs - turbocobra
Agreed, brother, and I love your work, too!
My mind is hungry for knowledge about so many fabrication and manufacturing skills and technologies.
I've been enjoying Jody's content for about nine months, but I've been watching your channel for well over a year.
Also like to give recognition to Texas Barndominiums. Another great channel and talented people.

Another great video! I noticed finding the right darkness in my hood really made the puddle stand out. Usually run pretty light. Turned it down to 12 and what a difference. Also I like to lengthen the arc and dab right under it, not the front of the puddle. Takes the stickiness out of it. I’ve only welded it once but it was like a million pipe cuts. Reminds me I need a new tig finger sir.
keep the Ti vids coming buddy!
Would love to see you cover more on ti pipe welding, different ti grades, and more ti welding techniques. Your videos have been an excellent resource for beginners like myself!
I was a team member TIG welding titanium pacemaker clamshells. We used a glovebox which we would pump down to just a few microns, break the vacuum with argon and pump it down again. Then break the vacuum with argon again to atmospheric pressure. The argon was from a big dewar tank with liquid argon. All the connecting piping was brazed without any flux. Small leaks were tested for by pulling a tight vacuum and waiting overnight.
We discovered that any leaks with argon gas -even under pressure- would cause a backflow situation introducing oxygen and nitrogen into the argon cover gas. Nitrogen was especially bad because the TiN layer was extremely hard and even more corrosion resistant than titanium itself, but contaminating the weld internally. Much of the straw color you see is probably TiN because it looks just like the straw color you see with steel in the HAZ. When properly set up, there is zero color except the silvery color.
You also must be anal about cleanliness. Most of the clamshells were vacuum annealed and put in sealed bags. The hydrogen really cleans the Ti at the molecular level. All this is what we felt we needed with a medical device, but it is impractical in the rest of the real world. But, you must have really clean parts and really pure argon for a quality weld in the real world.

Your practical tips have been very helpful. Thank you.
Always a great video offering from you Jody, Thank you for what you do. I am a pretty good basic hobby class welder as a result of your teachings. And I do but your products like tig fingers, cup sets and videos for their usefulness and to show my appreciation.
We all got what we’ve been waiting for haha. Thank you learned a lot I didn’t know
Thanks for the tips! I just recently worked in Titanium. I machined and ground a few small pieces at the request of some knife maker friends. It defiantly has its own set of rules. I was told by one of my subscribers that heat and oxygen causes Titanium to oxidize and changes its properties and making it difficult to work.
Steve
You ought to be a college welding teacher like bob Moffett, earn from weekly classes and have the videos as extra. Ive learned almost as much from you as i have from my grandfather about welding hands on. I really appreciate the time and effort you put into these videos and your ability to identify problems and explain your reasoning behind them. If the world had more jodis like you, tradesmen would know what and why to do before they get 10-15 years under their belt. Thanks jodi
Wow thanks, the slo-mo was an eye opener for me.
Thanks for another very interesting video. Just love what your doing.
Thanks again.
Awesome video the best shots and plain information around.
Another good tip thanks for inspiration
I always liked welding Titanium Aerospace parts.
never have to brush anything
with perfect purging, it welds super easy
Very educational video. In a 10 min. video there is so much information to learn from. Jody's is a great instructor. Great arc shots to explanation. Thank you Sir.
Man i love your videos... thanks for another great one.
great video as allways ! Cheers and thankyou for doing this !
Great stuff, Happy New Year !
Thank for your every video
I'd like to see more about trailing shelids maybe even make one, would be a nice little project
Thank you for your time and I’ll buy only from your store!
Love your videos!!
Great video (explanation) Thank You. Happy 2022 New Year.
I love the burn hole in your t shirt. Looks like some of my Sunday go to meeting shirts. Don't know why I noticed it, but I thought it was funny. Can always pick a welder out of a crowd!
Good content Sir more tricks to watch out for love it!!!
Very interesting. Thanks Jody!
A battled with bad argon for months, no one had heard of it….now it all over CZcams.
Man i love the slow-mo. Great video as always, thanks. Btw ads don't bother me in moderation. Whatever you have to do to keep on keeping on! Work just bought a Dynasty 210 I am looking forward to playing with!
Awesome Jody, thanks.
Really amazing welding footage... top-shelf!!! 🇦🇺🤜🏼🤛🏼🍀🍀🍀😎
Great video. Looking forward to the bicycle frame video!
I have an s sized tank, same as you had issues with AND I've noticed similar issues this time around. Luckily nothing critical and down to 500psi so won't be long, but I will look into a t size on refill. Thanks again for great content
Another great lesson, thanks,,
I 100% agree with you on the owner tanks!!!! I ran into that problem a lot!!!!😉👊
I'm paraplegic and use wheelchairs. I recently cracked my foot rest which is made of titanium, and looking inside there haven't been much if any shielding gas as it had been spots of scaling as well. The crack had started in the welding area and I'm pretty sure it's because of that oxidation.
Titanium wheelchair parts? Fuckin minty man.
Been waiting on this one
Thanks for the video.
Great vid , been waiting on some tig welding vids for TI, looking forward for the next vids on this. PS. Wish I had seen that you were in Chatt would have like to meet you, maybe nxt time. Keep the great vids and products coming
Love the video.
Beautifully shot video here dude!seriously great stuff here,pure gold😎
Great podcast today with Andrew..
Thanks so much
Nice thanks Jody!
Funny you should mention accidentally welding titanium with stainless filler. Within my first couple of weeks of welding titanium I made this mistake. To a guy with almost nothing but aluminum experience up til then, inconel filler looked pretty similar to titanium. I ended up welding about a quarter way around a piece of .049 wall .625 diameter 6AL when I noticed an almost 'glass breaking' sound. That was a valuable lesson that cost quite a bit of time to correct.
Great videos, sir. Keep it up
Good stuff jodi
Jody is any builders dream neighbor.
Thanks Jody !!
I've run into the bad gas problems several times, seems like it didn't show up much welding 316 stainless but trying to weld aluminum with it just didn't work, it made me think the material was contaminated, finally decided it had to be the gas after trying everything else, so I took the cylinder back to my supplier and told them what was going on and there response was "oh you must have gotten one of those bad cylinders of gas" . They said whoever filled them didn't purge the manifold and they had several cylinders returned. Since then I've had 2 others that were bad over about a ten year span.
Big beautiful weld cup
I am truly amazed at your knowledge and instruction! Titanium is wild! Again, I would like to thank you for posting these top of the line instructional videos! I look forward to many more welding videos!
How about something on the purge fixtures? I tried making one out of copper sheet and copper strands inside the perforated box. The one I made didn't do so well when I tried it on the back side of some 16 gauge stainless.
An old sand blast cabinet works well for a purge box for welding small titanium parts. It takes some getting used to though.
Amazing how much Argon quality can vary from cylinder to cylinder.
Thank you
I would be very interested in seeing how to weld titanium tube, I'm going to be building a turbo based gas turbine and I may make the combustion chamber out of titanium, at this stage it's just going to be a small prototype but if I can get good efficiency figures I may scale it up!
Do you have or could you do a video on dating technique. Your vids have helped me so much and I'm starting to get some decent welds on stainless. I'm getting faster and burning my welds less. But I find as I'm dabbing the rod is getting stuck momentarily at the front edge of the puddle. If I add a little more torch angle the rod tends to ball up? Love your work mate.
정말 잘 보고있습니다~~~^^♥♥♥
Great Video! Can you show us how to make the purge fixture
REALLY helpful Jodi, you know so much. I have a question in shields, the quality of the lens.If you weld a lot, is there specific speck you need to look out for, like duty cycles on a machene, to avoid long term eye damage?
Many years ago doing multi pass welds (MIG) for weld test proceedures, test plates failed x-ray due to porosity. Plates were welded in an area shielded from drafts etc. Welding Engineer had witnessed all welding tests. Turned out to be bad gas, not me, but the gas bottle I had been using. New bottle, welds all good. The little things tnat can make the difference.
just awesome welder thank -canada
Great video Jody. Some newbie questions if you could be so kind. What electrode did you use for this? What is the classification for the filler rod?
Thanks
Good video amazing how thin that is, I love tig welding I want to learn more
Hi Jody would you be able to go over a bit about titanium grades and the upsides and downsides of welding them , I hear some grades are more prone to cracking ect.
Thanks for the great video. I woukd have never suspected the cylinder. I assumed all cylinders wether purchased or leased are the same quality. Have you ever used UHP Argon to ensure the Argon is pure?
Is there a certain “grade” of argon to ask for to avoid this
Hey Jody! Would LOVE for you to cover tips and tricks on welding thin wall titanium mitered tubing. I work in a custom fab shop that builds titanium bicycles and would love a short vid on tips, pulse, heat, ect. We use .035” 6-4 Ti tube.
I'd like to see how you make a gas fixture for welding Titanium please!
Great video. I’m hoping you can help me with my question I have a titanium clutch can and I need to weld two 1/2” nuts on the inside of the can in order to mount the motor. Is there anything I should be aware of before I have this done and if done properly will the welds be strong enough to hold up to the vibration? I’m not holding you to this, just your educated opinion. Thanks
Bad gas was brought up in the shop today as a possible cause of porosity we were experiencing (in alum). What a coincidence that I wanted to see some titanium welding, and gas was an issue! Who says the interweb is a waste of time!
Great stuff Jody, on T joints do you still need to back purge, or not since you aren't penetrating through to back side? I'm planning on building lightweight suspension components for a drag racing snowmobile
VERY informative video Jody.
Any chance you can get your gas supplier to analyze that bad bottle?
Good video Jody 👊🏻 learned a lot . Were would I go to get titanium coupon plates like that? I’m going to be getting myself one of your dual flow meters in the near future they look nice and are affordable compared to other prices I seen. Man I’m having some trouble with my everlast tig I think it might be gas too or it has to be the machine if not gas. I get these crazy arc starts on my everlast 210ext tig . On all materials recently moved to Florida so wondering if humidity could be the problem wouldn’t think so though. But the arc starts go away if I turn the pre flow to 1 second minimum. Still bad starts if I go to .8 seconds or something like that. Even if I turn the start amps up still does it. And also I have no gas leaks checked everything multiple times . And I’m on my 3rd or 4th argon tank from same store every time airgas I’m using a 125cf tank too . Next time I’m gonna try another gas company to see if that’s the problem and also gonna call the support team from everlast. Love your videos Jody you the man👊🏻🙏
Yes please have a video showing purge monitor
Another good one Jody - rather hope I never have to work on Ti!
Hey Jody, cool video. Could you make a video detailing starting points for TIG, MIG and stick with values also in metric? I would be interested in gas flow, amps and volts and also travel/wire speed for full penetration.
Hey jody, how do you keep such a steady hand in both hands? You don't ever get nervous?
It's a good idea to also get the oxide off the filler wire aswell
Just took a titanium test it’s like running water! Not bad though cool test
Have you ever seen someone build a race car rollcage from titanium and if not how would you do it
Hi, very helpful video, thanks. I want to butt weld titanium (pure grade 1 and 2) of 1mm thickness. Question. Will it be possible to get a suitable weld using just a shielded hand piece and a chill block made of high grade aluminium alloy?
Jody what about using crystal Argon vs normal Argon.I use normal Argon for steel and Crystal Argon for Aluminium.
Jody w Polsce też Cię oglądamy i żeby to filmiki miały tłumaczenie. Dobra robota
nice!! 💪 👷🏻
Can you fuse titanium schedule 10 pipe like you can sanitary stainless?
I love Your videos so much! You are so good! Everytime i see something new! Thanks so much! 👍
Hello, please tell me which cup number configuration is your go to settup, I can't see on vid cup number.
Thanks,
Someplaces you have to pulse weld with a pedal. I work in an Aerospace company and that's how we weld on Ti casting and Fab work. Here's a question what alloy of To are you using?
Can you give an opinion on the MT200 welder you are using? I seen very little reviews.
What tungsten are you using on ti and what diameter of filler wire was used
Please cover a purge monitor
I agree with the gas issues , I worked for ten years in the food industry lots of purge tube welding stainless and one company I worked for only bought from one supplier because their gas was much better quality ! The company I work for now don't see the issue and I have such a bad tim9 with aluminium some days you can see the impurities flashing out when your welding !
