I take a sick pleasure in repairing cast aluminum. The parts are often not replaceable and it's up to you to save the day. Even if the weld itself tries your skills it's rewarding to see the smile on the customer's face

Very good video Bob, I like when you show "actual" jobs instead of welding coupons which only shows "part" of the job. You need to see REAL problems and how to deal with them and get a good outcome. Well done.

nice video of the arc, especially the junk floating around in the pool. nice work cameraguy!

Cannot get over the, "*sniff* yep, that's carbide burr..." part.

You got lucky with that aluminum casting being of a better quality than most. I’ve had some nightmares in my day. Looks nice 👍

Artisan craftsman doing great work as usual. Thanks Bob.

I welded a cast piece not to long ago (engine oil filter bracket). Was dreading it, ended up welding real nice and clean! Was a nice surprise.

You are not just a welder, you are an artist!. Great control over the flow and feed rate. I was impressed by your work. Now I want one of those welders.

I bet some junkies would love that spoon.

Hahah years ago I had a dream where I was walking through the woods and came across a group of old junkies who had just taken a bunch of poppy plants from a field and were cooking it up in a massive spoon like this. And they are using syringes the size of a turkey baster. So weird I still remember every second of it.

Hi Bob. That was fantastic. So many things could have gone wrong but in the hands of an old school artisan like yourself there was only one way this was gonna turn out. Thank you very much!!

Ha, he smelled the carbide, my father used to do that when he was teaching me the ropes.. Old school, love it.. Thanks for sharing Bob. !

Skip the “premiere”. All else is just geat. And thank you for your time and efort to educate the world.

I love how you spoon feed us all this great info... :)

Bob is the definition of cool.

That was a great segment. It was very educational, as I have a compressor that dropped off my truck and busted a motor bracing. I am looking for excuse to score me a general type welder, and this added to my list of reasons. Making that wedge was new to me, as well as the way he just allowed the aluminum to melt into the wedge, and of course many other things. Thanks and keep up the good work!

Great video, not many people try welding cast. Great work

Very educational I may be welding cast aluminum in the nest day or two so I’m trying to learn as much as I can before I even touch it, thanks bob!

Funny,! but most of all I appreciate you waiting for approval from the feedback from your customer. Sometimes that patience saves a lot of re-work. Absolutely fantastic hall pass!!!!

Ain't never done TIG but it's on the bucket list good video on this thumbs up.

Every time I watch a video from you guys it makes me want to go weld (and usually end up doing so, haha) Keep up the great content!!

Really nice camera work. I don't know if I've ever seen a better video of a weld in progress.

Man I thought I was a crappy welder but apparently this stuff is tough to weld love your videos you and Jody are the kings

This video has some awesome weld footage. Very good detail. Thanks.

Man its good to see the right tools do a good job

Guess I am a little too old to attend one of your classes but I DO enjoy watching your skill set. Thanks Much.

nice to have the customer show up

Very nice detail on the camera shot of the actual weld and penetration. Greatly appreciate that! And well done on the weld.

man this job brings me back to my last employment,,with Al i keep a 99% balance,it needs very little to work AC like that and does a great job penetrating once you find the right freq etc ,used to get bubbling when patching leaks on a hydro test around the diesel tank seal but once i discovered this trick no more bubbles and full penetration seal

Another useful video. Good advice on use and handling of the burr. I have cut a lot of aluminum over the years and have found that putting wax on cutting tools - burrs, band saw blades, hack saws - keeps them from loading up and provides better performance. I use bee's wax, but any paraffin wax will do.

Great vid. Question have you ever used aluminum electric cable strands for filler rods? Me being a cheapo I tried using it ( alum electric cable ) tig welding aluminum on some yard art and it seemed to work.

One of my favourite aluminum welding videos 😊

I started welding alum. with a torch back in the 60's.... We had an "OLD" school welding instructor that could torch weld Alum. Foil. Now the one thing you didn't do is wash it down with acetone first, Then you wire brush the shit out of it, THEN wash it down again. Let's face it: "YOU GOT LUCKY"

Uncle Bob ! everyones favorite welding coach.

Camera work is amazing. You can see the puddle and arc very clearly. Thanks for sharing.

I wonder if it was cast in 2 parts and welded together at the factory. would explain why it welds so nicely, and such a system makes a lot of sense for low volume production

Beautiful work!

Welcome back bob been asking about you!

Perfect job for muggy weld!

Thanks for the helpful video and info great video you the man bob

I would be very interested to know if the spoon is still in service at the school !!

Good video, but one heck of a hall pass!! That's one big baby! Great job Bob!

Thanks for an interesting video, with regard from Russia

Great video, thank you!

Smell the carbide bit lol. Good vid on cast alum. Didn't look like much pepper or trash in base metal.

When you tacked that you could see the impurities in the cast, I love tig welding aluminum but aluminum holds so much trash and oxidation

Great job, looking great

I guess no one is going to forge that hall pass! Good video -- Makes me want to go find some scrap cast and try my hand at it.

8:20 Ugh, God I’m at the dentist getting a cavity filled 😖😖...made my spine tingle. Nice job on the cast aluminum repair. Definitely learned something useful.

It is my spoon?I lost it thousands of years ago. Haha, really good video.

That's the last thing I expected to see! 🥄 Always funny looking 🤔 to see aluminum become so saturated by heat that it says, *"Enough!"* In the split second it glazes over with that dull finish and just before it falls through the part... I want that spoon for chili and ice cream with cake! Too darn cold and too soon!

Great Job

Hello Bob Could you please do a film on Lincoln STT and give an evaluation on weather you would consider it a onsite option on small pipe or just a workshop process. Thanks

Well well, I now know how to fix my spoon when I break it. It was always in the back of my mind 🤣 Great video thank you Mr Bob! 👍👍

Wow, you are awesome!!!

Great video. I've got some cast aluminum I want to repair with my Everlast welder.

A quick question, how we identify no need for Preheat / PWHT for this Al Cast as they are susceptible to initiate cracks???... Thanks and good job...

That sounds like a dentist at work... I will a new gas to keep watching. Nice job, sweet spoon.

Thanks Bob

that's not a high production cheap casting. I always find that a custom order specialty type casting that was a decent alloy for welding.

I wouldn't want to upset the fellow that uses that spoon !

That's great In high school, my welding teacher had a key to a faculty restroom which was next door to the shop. Instead of us having to walk all the way down to the main restroom, he would giv us the key. To be sure that nobody ran off with the key, it was attached to a small section of 6 inch aluminum pipe with a chain.

I do so much cast aluminum welds and not once have i had the luck to get that clean a base metal. Mine are so full of crap, porous and soaked in oil i dread it every time. Just yesterday, i had to weld a leaking portion of an injection die, should have been massive 6" thick casting and there was a massive web of cavities filled with crap not even 1/2" under the surface. Spent the better part of eight hours to clean it up and get the working end of that shit back to the original profile. Anyway, thanks for the demo. As always good ripple pattern and pretty interesting chain.

Nice and good work.

What’s a good process if you don’t have a welder will brazing work and if so what type the part is off a Honda big red

Is it possible to tig weld copper pipe with silver solder for an home air conditioner ?

nice job.I enjoyed the video. Dan

It looks identical to the prop that the Lovin' Spoonful used to suspend behind the band when playing concerts and TV shows.

Fantastic

What did you use for a filler rod ?

If the material started as ingot, it is most likely 356 or A356. The material will usually be better to weld on the "bottom" (casting orientation) because dirt floats. It's also best to grind out any porosity in the weld area . Then stress relieve, quench, and straighten within 4 hours, followed by aging. The material will age at room temp but may take months to get to full strength.

Can you explain welding on the bottom/casting orientation and its relation to floating dirt? I know that when heated dirt floats on the surface but i didnt understand what you meant

i like the die grinder, what kind of die grinder is that?

Very nice. How about welding some aluminum on a cast alum intake for a six cylinder

Hi I have a frame of a P228 pistol that’s made of n I quote “hard anodized aluminum alloy” the frame slides that groove out to slide on the top slide has worn in many parts. My question is can the be welded where the groove is missing n built up n then carefully filed down to blend in with the parts of the groove that’s still there. Basically building up what is missing. Thanks in advance.

Have ever thought about using muriatic acid to clean your cast aluminum or any aluminum?

I wonder if you used any carbide burr on this?

So therapeutic to watch. And I can't even weld.

How about a 1"x 1- 1/4" strip skip welded or screwed on back side for additional support with a nice blending of the weld on the front? Gives both support and esthetics .

Very wise to use non cross cut die grinder burrs! They're better than people think!
