Brass Brazing | Welding with Joe

- I beat and bash my way thru a refresher on brazing, modifying a brass radiator, and learn that I never want to mess with brass again if I can help it. I did play a bit more with it after this video, and realized that my 1/16" filler was a major part of my problem. Getting some .045 or .035" tig filler would lower the amperage required to melt the Sil-Br and reduce the chance of melting the brass. Sometimes, that's just part of setting up a welding procedure - trial & error.
Thankyou for the safety tips. I did not know the dangers of using chlorinated chemicals during welding. Also the great explanation of your tig pulse settings was interesting to me. If it were me adjusting that radiator for my boss I would have just found a pipe that fit the inside diameter of the inlet and got my phat friend to stand on the radiator while I pried that sucker into an upright submission. Like I tell my boss: If you wanted it done right then you should have hired some other slave.
Would love to see the process
Higher silver content is better for joining brass. We use 45% silver brazing alloy for brass. 15% silfos will work, but not recommended. I didn't see if you used the flux for silver brazing, but that may help as well
I'd looked at using a silver alloy, but at the end of the day, I'll probably never use it for anything else, and I'll have plenty of others uses for this Sil-Br, plus it was recommended as a suitable filler. I just forgot to mention the silver alloy filler in the vid, so thanks for bringing that up. I did try playing with flux. I also tried AC. Out of everything, the diameter of the filler is what killed me. I tried it on some thicker stuff the other day and it worked nicely.
Id like to see some videos on welding issues or does and don't for stainless and aluminum
Also, do not use chlorine brake cleaner to clean injector bores. I replaced all eight injectors in a medium duty GM 6.6L. I started the engine and it about killed me. It was burning the chlorine and sending it out the exhaust. I had to run out of the shop, I couldn't breath.
Thanks for showing the ugly weld, it's honest, I appreciate that.
I can smell this video. I will never braze brass again 🤮
Why didn't you show us the process? Would love to see that. What I would really love to see and learn is the old school methods for brazing and soldering. Like that would have been done in the 1950's or earlier. I just found an antique bernz gasoline blow torch and it got me thinking. I love old school anything. I daily drive cars from the 80' and 70's. We used to have a drive shaft shop in town that also repaired radiators. But I heard the guy died so the radiator business fizzled out. We live in a terrible throw away culture these days!
I really think it would pay some young folks like me to learn some of these techniques before they are lost. People with antiques that they want to keep that way would and will more pay big bucks I'm sure to have things repaired in the correct methods. Think in terms of someone like jay Leno wanting to have something repaired on one of his old rare steam powered cars. Of someone was very good at doing that work in the time period correct way. I'm sure people like him would pay well for that. Probably have guys sending you things from all over in the mail to fix! Maybe it wouldn't be a source of full time work. But a really good and important side job at least.
Also not to be a dick but for the very small amount that inlet had to change direction, and the amount that you buggered it all up... Wouldn't it have made better sense to leave it alone? After all it is more likely to leak or break now I would imagine. And radiator hoses are very forgiving..?
I was too busy trying not to die from all the zinc fumes. I'll never attempt this job again
@@doomsdaydiesel haha. Really? I always thought zinc was good for a body. It's some of those other ones like mercury and lead you gotta watch out on..
It's funny how in today's world we are so worried about being clean and sanitary. Honestly most of the old timers that worked around alot of hazards lived to be just as old as they do today. I've lived in a house with tons of asbestos covered pipes for nearly 30 years. That's one of the things I do take kinda serious..
And just to poke fun at ya a little bit... But I don't think you will be too ready for the doomsday with that attitude! Haha. Take care friend!
Bizarre you have spent all that time not showing us how you did it and then tell us you were trying not to die from zinc fumes despite having a respirator. I suggest you delete this video or at minimum change the title to ‘Not Welding….’.
