Eutalloy Repair on Rotorshaft Part 1
Vložit

- This is some video footage from my archives that I never used. It's about using another welding process with metal powder by Eutectic called Eutalloy. It involves a special torch that heats the metal and flows metal powder into it to form a puddle and build up the surface, kind of like brazing.
I used this technique on a shaft repair on a electric motor shaft that was badly work and corroded.
This process is very beneficial to many different applications, it's just very rarely used. Maybe we can come up with some more jobs around the shop to showcase this neat process.
Man!! What a cliff hanger...LOL. Great video and thanks for showing yet another process for building up shafts!!
Never heard of eutalloy before. You are full of surprises, even the beard caught me off guard at first. Thanks Adam
loved the welding shield on the go-pro, was able to the material much better as you pulled the trigger and did the build up on the work piece
Adam,
You sure do know a lot of different cool techniques! Thanks for posting.
Eric
cool new process of building up material. I'v never heard of this one.
You always come with some new stuff, Very knowledge full you are! Like a Jedy.
Ha ha, thanks Martin
I thought last weeks spray metal video was the coolest thing I've seen on this channel. I was wrong
I gotta try and keep you guys on your toes
Glad to see some of the older, in-the-can footage. Good to see this. Still hoping for heavy metal machining part 2.
100 times or more I've had a similar situation and didn't know that this process was available. Thanks!
The welding shield was pretty cool. Never seen what it looks like through one.
nice job Abom. I am learning from your videos many interesting technical things.
Cheers from Lithuania!
Hi Adam, I sure hope that you do not get caught up in the Hurricane Matthew even though your property looks very stout and sturdy.
Good luck to you and others in it's path.
I think the welding shield is cool looking shot....nice job
it is always interesting to see things i have never seen before
Another flashback memory. When I started in the machineshop in the early 70's they had an oxy/ acc spray machine that melted a wire and sprayed it onto the shaft. Veryyy noisy dirty. Later we went to the powder spray system.
So this is similar to metalizing like your previous videos, but different material characteristics? Oh and Keep the beard man, beard is life! Oh and that intro music is sweet 👍🏽👍🏽👍🏽👍🏽
Can't wait for part 2 to see how it cleans up.
Nice video Adam. I love learning a new way of re-cutting the center of the shaft. The lens at the end gave a cool view of the torch!
Awesome video! I always like the other "repair" videos with you doing other kinds of work besides on the lathe or the mill (but I like those too!) Even though you couldn't see much, those welding shots looked really cool. Keep up the quality videos!
Just to mention something about making videos. You think the light is going to be too bright but the cameras normally have a very narrow light spectrum sensitivity. The blue light from a torch or arc is mostly in the UV spectrum. It blinds our eyes but the camera only detects the blue-violet fraction of the light. Thus you have a small over bright area but the room around is detected normally.
A similar phenomenon occurs with the torch cooking metal. Most of the light is in the infra red spectrum. Some of the white light is detected but again, the room around is illuminated normally.
When you attempt to use a darkened lens however, it simply doesn't work because most of the tiny amount of visible light in the cameras detection range is blocked. Thus you just get that dim glow.
I have a Eutalloy Torch Kit at home, its in a wooden box with various types of alloy powders. My dad gave it to me years ago, have never used it.
Adam, I was watching one of This Old Tony's welding videos the other day and I don't know what filter he uses but you could perfectly see the metal pooling clearly as if you were looking through a hood. He may be a better comedian than machinist LOL but he's great with the camera work and editing. I cracked up the other day when he added the skit with you calling him and him telling you to plug the lathe in to make it work.
It's interesting to see some older video footage, since the video was taken you've changed a lot ;-)
I've never seen these brazed on inserts used in your videos - i'm enjoying your videos round about a year.
You definitely describe better what you are doing in your newer videos.
You have done a great development on describing us how you do it the Abom way.
(Sorry for my bad english ;-))
the return of the amish beard!
I kinda like it more than the babyface Adam :D
That's the first thing I thought. Amish boy with a chew in.
what a good cliffhanger
hope u continue soon
still so much to learn
thx for sharing your knowledge
interesting! why'd you sit on that footage so long? I've seen spray welding but that was new to me.
Thanks for showing that I`ve welded all my life heard of this weld never seen it , You almost need a trough to keep the side spray confined onto the shaft ,Just have to figure out what does`nt hold powder while spraying , Man wish I had this when I had my JD 40 Dozer the block was split up the side of the eng . Could have squeezed the block back together and fixed it ths way . Does good job .
Great video! Really glad you decided to continue your CZcams adventure, you have so much to showcase and contribute to the community..
With that said, I really like the music at the end of the video.. could someone give me a hint :)?
Thanks Patrik. Search youtube for East
Thanks for the caption Adam, I thought you'd grown a beard overnight!
I'd have to say the gopro maybe isn't the camera for welding (at least not without a different filter), but what you've got really shows the powder process off very effectively. Keith Fenner has done a few pretty good welding segments - so it's certainly worth pursuing, done in split screen with what you have there would have been a very effective shot.
Pretty cool process. Looking forward to seeing the final results. Thanks buddy!!
Brian Streufert Thanks Brian
never seen that technique before,think I would be more comfortable spray welding myself,great video
They each have there uses. Spray welding is great for shaft build up, but sometimes you have a part that needs built up, like an edge, or flat surface.
I just picked one of these up at a yard sale last weekend .
That was very interesting, thanks for sharing! Can't wait for pt. 2
That welding lens cover for the go pro is pretty cool. I bet it would work better if the glass was a little worse at filtering. Eyes are way more sensitive than the sensor in that camera (or I should say sensitive in a different way). With less light blocked by the filter it might start to perform as if the view was similar to yours.
Great videos. Thanks for sharing.
I don't know man, I think I may have mentioned before, perfect for any type of build-up that's not stainless... Lincoln Outershield 71m mig wire. it's a flux cored wire, ran with shield gas leaves that pristine brazing appearance. flows like butter, super smooth and clean. very machineable. undercut shaft, run a lap, double lap on the end of shaft, and even the outer edge on the face of the shaft. I really think you'd enjoy using that stuff.
i was so confused when the video first started and i saw the welding table project and the beard
SuperAWaC I knew it would throw a few people off
SuperAWaC
SuperAWaC
Adam cool video thanks for sharing.!.!.!.
Eutalloy seems like an interesting process, I thought the welding filter on the lens looked cool
Hey Adam I like the beard it makes you look like a real distinguished gentleman .
I had a tough time with it, don't know if I can handle growing it out again.
I have the same Lincoln helmet that you have. I bet the shade 5 setting on that would work for that type of shot.
very nice , thanks for the video .......
one thing i think that would be very cool ABOMB is that you put that steady rest in the bead blast cabinet. just saying!!! would make for another great video as if you didnt have enough
Very interesting vid. Love it.
Do you think this process bonds to the base material more than the spray weld?
Brian it's very much like brazing. The molten powder fuses to the base metal.
Thanks for sharing
Loving the channel. New subber :-) Trying to start my own tool making business starting from scratch, nothing but the rags on my back :-)
Man, bring back the beard.
Doesn't matter the shape or size of the beard, its still better than no beard at all...
+Abom79 So Adam, what is the cost of getting the equipment to do this? Is it that much better than just welding up the end with some 7018 and machining? It looks like you get the shaft pretty hot, so the steel probably moves quite a bit. Just curious what the pros/cons of a process like this is. Maybe that discussion deserves a video? Aloha.
They still make this style of torch, and the powders but I don't know the cost. I do know it's very expensive though.
hi Adam try that welding shade again but change the camera to fixed exposure instead of auto as the camera is changing the level of light
YES ADAM, you grow that beard! looks good man
That's cool mate! Great vid
Wonderful to see you decided to post this Adam, despite the fact the attempt to get a darkened shot on the camera didn't come out well. Is that why this one went in the vault originally? I like this repair method. 'Brazing' for non-cast, fully steel parts. Would it work on an inside bore also the same way that brazing of course can? I'm guessing so. ^^
I think the welding shot got me down because I had been trying and experimenting with it, but I don't really know other then I just never got around to making the video. Seems like once I move past a project I look forward. This process has great build up potential for many different parts and surfaces. The material I think is a better alloy then standard brazing rods.
Is it me or is the material you used to build up that shaft harder than the base the sound of the cutting seemed way grittier? Great vid man I do hvac always wondered how motor and tool shop guys get em back in working order!
Did you not heat the tip of the shaft up so much that its properties have changed? Is the base metal still fit for purpose?
Retro Abom. Love it!
Cool video Adam! You got that shaft really hot during the welding. I would have been worried that the heat would have traveled up into the motor windings and did some damage. I didnt see a heat sink - did that cloth have something under it to absorb the heat?
great stuff Adam.
Would screwing some sort of heat sink in the end of the shaft help with the overheating problem, a piece of Stainless or something to balance out the heat
my thoughts exactly...demented minds think alike, LOL!
Phil's Projects Very possible it would help, or maybe even cause more work by it getting stuck in the hole or the metal fusing to it as well.
yep definitely a damned if you do and damned if you don't
Seems to be more precise than the metalizing.
Just a question on your measurements, because you faced off the end of the shaft should you have measured from the bearing journal out to the shoulders and not from the new cut face back.
Thanks for the video's Adom, I away look forward to them. I never know if its impolite to ask/request something, but here go's anyway - I was wondering if it were possible to film though a filler so we get to see what you see? Personally I'd find it fascinating.
Did you watch the part where I tried using a welding lens over the camera?
Ow man, How did I miss it. So sorry. (I have only one excuse - Beer. ) . lol
Have you ever done the stainless sleeve repair on video? Just wondering how much you would have to turn down the shaft.
Nice beard, man. *thumbs up*
yikes wheres the hat and the horse and buggy..and wheres the rest of the barn raising crew.....j/k...hahaha....good stuff there man ..what took so long
Can you use other brand powder in the Eutalloy torch? I have a older torch I'm wanting to hardface dozer blades cutting edges and loader bucket edges with it.
So why use this technique instead of tig welding and then turning back down to size?
How do you know you’re not going to cut or liquify the shaft?
Nice!!
I was wondering the same as some others if a bolt screwed into the shaft might have helped coated with the mask you use when you when you metalize. Or, would the threads weld into the shaft?
It's very possible to weld the bolt or threads to the shaft if your not careful.
I was thinking that same thing a under sized rod or rolled up asbestos cloth put in the end to keep from welding to threads.... But I'm sure Abomb had thought of all that prior to jumping in and spraying metal all over a customer's part. After all it is Booth Machine Shop 🅰️💣
Hi. Can or have you done this spray welding on cast iron?
What brand name is that bronze o chrome? Thanks
Have you tried a auto-darkening welding lens?
Is it possible to do this while turning in lathe?
Curious that I don't see the fume extractor... is this process less toxic than spray welding? Or perhaps you had it there and I didn't notice.
scowell I don't think he had the fume extractor working early last year.
I didnt have the fume extractor at the time I filmed this job.
i was not send by AvE! :)
in hind sight, would a bolt, threaded in the part, make the heat distribution more even making the metal flow like the top piece?
Would a copper bolt or stainless have worked?
even better, have a large carbon block bolted to the end, then the weld wont stick to it
Filter is too dark, may want to try a shade lighter.
have you tried an auto dark setup
That beard -_- is great :D
Something seems different.
Ask Keith Fenner what he uses for a welding cam I think he. has an auto dark shield..
He also uses a different style of camera with manual focus and zooming.
haha, awesome, I thought: man, this guy grows a beard in NO time!
BRING BACK THE BEARD!
Arggg! Pirate ABOM!
The Gopro needs a lot of light, so welding lenses for "humans" are too dark!
Regards, Matthew
Yes Matthew, I figured that out a long time ago, that's why I never used the footage I did of testing it. I mentioned it several times that the Gopro is not the right camera for welding arc shots in various videos.
That beard made me wonder if Adam is changing his religion, LOL
if you've never seen Idiocracy you won't get why the name of the powder is making me giggle everytime I hear him say it 😂
drink Brando. It's Got Electrolytes. 😂
Brawndo stupid auto correct
Adam i coulnd find any other way to reach you hope you alrigh. through hurricane matthew im in the carolinas im next lol hope you and your family is safe
We were all good here in the northwest florida area.
how do i get one of your shirts i want to support your channel
Right now I am running a teeblaster campaign for one of my Shop Life shirts found here www.teeblaster.com/shoplifewelder
That beard is a fire haZZard...quick!... wrap it in some of that fire retardant cloth and wire it on real good and ride it out brother!
Adam's gone Amish!
that beard tho
Abraham abom Lincoln
I bet the girls liked that .
They never tell me
Amish Adam.
Don't grow a beard like that with a name like "Abom".
Not new, clever, funny, or welcome bro.
Lighten up Francis.
BlownF150
Why?
Hahahaha
Lucas You're the only one talking about offense...
Too bad they don't have a similar tool to use on humans. 😝
I've heard ionizing radiation does wonders to human flesh but I'm rather sure the long-term prognosis for metal pieces is better ;-)
hboy007 Haha, very clever Sir.
I am sorry unprofessional work
Retro Abom. Love it!
