I've got an idea: You've heard of companys making diamond edged tools through brazing, And any science nerd will know certain types of radiation are blocked by certain things I'm thinking it might be possible to do this but with concrete and a lead aluminum alloy and coat it in a paper pulp that has been made fire proof after trapping powdered concrete in a lead aluminum alloy matrix In theory this should make a super material that blocks all the types of radiation
I bought the the Bernzomatic TS8000 today at Ace. Just now tried it out by brazing two steel galvanized washers together. I also bought some fluxed bronze brazing rods but I used an aluminum rod on the washers and it worked well.
@@user-yg6dq3lt7f I'm aware that the fumes are toxic but two small washers put out practically no fumes and one would have to inhale a LOT of fumes to die. And as you see, I'm still alive.
Agreed unless you have the right mask and very good ventilation. Can sand it of but again good mask needed an£c you should extract at source with a high filtration vacuum. Brick acid works well diluted 50/50 with water and takes about and hour and you know when it’s all removed cos the steel turns rusty.
I couldn't figure out why googling tells me the propane burning temperature was higher than the melting point of brazing metals, yet I kept reading in several places it doesn't work. I've never joined metals without bolts, so I was hoping to try this to cheaply get the most basic feel for brazing. Thanks for showing it's doable.
Hi Everyone What kind of brazing rods do I need thanks 🙏 Is they a specific type I need at 1 1/6 of a inch Wanted to brazed a crack in a lawnmower deck...2 mm thicknesses it is.. It's a steel mower deck like sheet metal Much appreciate anyone's help?? Kind regards Greg
You need flux-coated bronze brazing rods like the Bernzomatic WB5. If you are fixing a bigger part like a lawnmower deck, I would also recommend a more powerful MAPP gas torch.
@@DragonBuilds many thanks for all your help..correct thickness of steel is 1.6 mm thick and has a crack that is 75 mm long on deck...it's a walk behind push lawnmower Much much appreciated for all your help Cheers Greg
Anyone familiar with the bernzomatic ts8000? What can I do with that, that I can't do with the 4000. Keep in mind that I'm not a welder but might want to make some repairs that would include basic welding.
It has around twice the BTUs as the ts4000. Now that I have an arc welder I don't braze very often, but you will be able to braze 1/4" steel rod or very thin 1/2" tubing.
You say that brazing isn't as strong as fusion welding, but the American Welding Society has an article on brazing that says this: "Brazed joints are as strong as the base materials being joined. There is a common misconception in the marketplace that brazed joints are not strong, and only fusion welding can impart base-metal strength to an assembly. Not true. A properly designed and brazed assembly will be as strong as the base materials being joined. Period. That means, if the brazed component breaks (fails) in service, the failure will be in the base material, away from the brazed joint. Basically, in a lap joint (the most common type of brazed joint), as long as the faying surfaces overlap a distance equal to at least three times the thickness of the thinner of the two members being joined, and the clearance between the two parts (the joint thickness) is kept around 0.003 in. (0.075 mm) or less at brazing temperature, the brazed joint will be as strong [as] or stronger than the base materials. Studies confirm this." The studies they refer to are footnoted: "Brazing Handbook, 4th edition. 1991. American Welding Society, Miami, Fla., pp. 3538." So brazing deserves to see wider applications than it does, and your video shows just how little it takes to do the work.
Why not just use the small oxy-propane or oxy-mapp torches. Very strong variable flame for not a lot of money. Getting the O2 cans can be a pain. They're just like the small mapp cylinders but red instead of yellow.
That torch was obviously ok for the small items you were joining, but anything larger would require more heat…high silver content silver solder works best when using propane only…
:( Step 1 is picking the kind of braising rod... can you edit that into the video description? Also, is the TS4000 for map gas or does it use oxygen with propane? Or just propane? My propane torch is just the most basic bernzo one, that screws straight into the propane canister. Would that work?
You really don't want to burn that galvanizing off without a respirator. All it will take is one case of metal fume fever and you'll never do it again. And yes, i learned the hard way. I'd happily have COVID or Swine Flu over metal fume fever.
@@DragonBuilds I actually have quite a few tools from Harbor Freight and have had zero problems with any of them. I have a $99 wire welder and a $129 arc welder in addition to many more items. I use them all the time.

Glad it worked for you. I had a Bernzomatic TS4000 and TS8000. They're hot but they're not durable. I like the turbotorch brand from Ferguson better.
@@DragonBuilds What do you mean not durable? I don't recall hearing you say that in the video. I paid $54.99 for the TS8000.
@@gitarzan99 It doesn't handle tougher environments such as soldering pipe in a dirty hole, etc.

Though you can burn galvanization off, I wouldn’t as it releases zinc fumes. As a welder I’m not a fan of “metal fume”.
That's correct but burning a little zinc is safe.

i cant get my brazing rods to melt with map or propane. it doesnt work for me. using benzomatic rods from the 2 pack
Which rods and which torch are you using?
I've found the standard propane torch does not get hot enough for bronze brazing, need to get a specialized torch that gets a lot hotter
I found that it works fine for smaller parts made of thin metal but it is not enough for larger parts.

Yes with good alloys brazing can be as strong as fusion welding. However, with lower grade brazing alloy the joint can be brittle.
What kind and name brand of the rod are you using
Bernzomatic bronze brazing rod
What are the filler rods your using name and spec
I used these brazing rods: www.homedepot.com/p/Bernzomatic-WB5-Bronze-Flux-Coated-Brazing-and-Welding-Rods-334490/203710172
Great video thank you for sharing this!!

Those work well but the disposable oxygen tanks are hard to find and only last 10-15 minutes.
Oxygen cylinders are heavy, expensive, difficult to store safely, etc.
What do u use to weld is it aluminum soder
For brazing steel, self fluxing bronze rods are used. For aluminum, use aluminum rods.
Are those aluminum rods?
No, they're regular bronze rods
@@DragonBuilds can you use brass rods with steel ?
That torch was obviously ok for the small items you were joining, but anything larger would require more heat…high silver content silver solder works best when using propane only…

It's just propane. A larger torch is required however. yours may not be big enough.
@@DragonBuilds Okay. What kind of braising rods?
@@DragonBuilds Most of hte ones I'm seeing seem to be made for Aluminum, or to be okay with ferrous alloys, iron, and steel, but use a hotter gas.
you don't need gas for brazing?
You really don't want to burn that galvanizing off without a respirator. All it will take is one case of metal fume fever and you'll never do it again. And yes, i learned the hard way. I'd happily have COVID or Swine Flu over metal fume fever.
I was working in a well ventilated area with fans, as flux fumes aren't good to breathe in either.
love it
It's unbelievable that Harbor Freight doesn't sell brazing rods.
Harbor freight mostly sells cheap junk tools, would you trust their brazing rods?
@@DragonBuilds I actually have quite a few tools from Harbor Freight and have had zero problems with any of them. I have a $99 wire welder and a $129 arc welder in addition to many more items. I use them all the time.
@@eyeballll A few of their items are decent, but most of what they sell is cheap junk. But the price is right for occasional or one time use items.
@@DragonBuilds I've had tools for 15 years from them. Still work fine.
Just make sure if you’re heating galvanized steel you’re not breathing any of that, you’ll get fume fever.
preshate that. yeah, all say you have to have the oxygen also but you have shown that not to be true. i have learned what i came for. much thanks.
You sound like you've seen one up close
damn you are brazing around alot of pressurized liquids :/.......thanks for the demo though!
