bought some of this over five years ago to repair a model engine mounting lug that had snapped off my FSRV boat engine which crankcase is made from some zink/alum alloy. preheated the model engine crankcase on a fire brick with a torch using mapp gas and approached it like I was soldering and digged into the flow from the filler rod with the stainless steel scraping rod provided and there seems to be a chemical reaction going on and the filler rod left a solder like joint which when left to cool was filed back and the lug is now as good as new. (it did not leave a mess like the work piece in the video it just looked like it was lead soldered)
Very nice. From my understanding, this is the correct tutorial. Many professionals show incorrectly. His skills at filling that small tube is amazing. Heat control is very important because those liquid metal can just drop. I am not a fan of the musics, too much repetition.
I've had tons of customers try this stuff before calling me to do a repair correctly. There's no substitute for TIG welding. Also, as far as using this junk to weld soda cans? It wouldn't hold the pressure, but if you need a soda can fixed, I can TIG that too!
Propane / Butane mix works well - I brazed a cracked aluminium pipe with it. It's enough to melt the pipe (about 1mm wall thickness), which I did three times and had to start again, if you apply too much heat. I managed to make the pipe airtight, even though I had to braze four sections.
I do believe that in order for a process to qualify as "WELDING" one would be required to "MELT" "BOTH" metals in order to achieve "FUSION". Joining metals with a capillary action ("THIS VIDEO") where all metals do not reach their melting temperature is either BRAZING or SOLDERING, depending on other factors.
me gusto mucho , pero donde puedo comprara el material que tu usas como varillas y fundente , los que he probado en mi pais me queda la soldadura como una bosta de gallina!
lets solder our internal engine components back together! a melting point of 380? haha nice. this is good to fix a lawnmower handle or repair a leaky pop can
Well, i think it could actually work. Your cylinder head is watercooled. It never gets as hot as 380 degrees. I think it's worth a try, before you throw it in the bin
i think its time to compare aluminum tig to this... put one next to the other in an arbor press and see which one breaks first... tig will win if it is done correctly
Did it worked? Just to let you know this is not actually welding this is more of brazing in other words your adding metal without melting the base and making them one piece. But how ever the resoonsability is on you. Good luck!! 👍👌
@@ricardogarcia4523 I have not yet have time to try it yet , but i thought about buying a welder and just start welding aluminium instead and then I'll get to thebtrickyer stuff
@FOXnewsAlien Alu isn't hard at all compared to steel. It's a bitch to grind only because it is soft and picks up on the bit. Try grinding it with a very coarse bit, using technical spirits or windscreen wiper fluid as "lube".. and if you're doing milling or have it in a lathe, get that cutting speed to at least twice that of steel. You'll do fine.
@Revco91 i take it you mean butane and propane! it's so funny when someone corrects another persons spelling, only to include bad spellings too lmao :) ain't youtube ace lol
I know this comment is old, but it would melt the head, you have to be careful with aluminium if it gets too hot. I don't believe you can have aluminium glowing red hot as it will be flowing by then.
For the people that think the Brits can't say aluminium, actually the Americans decided to pronounce it in their own silly way AFTER the British,witch is fine as long as you remember you are pronouncing it wrong lol
RelentlessRacingSA nah. The guy who discovered aluminum. First named it aluminium then changed it to aluminum then changed it backed to aluminium. So blame him
difference between soldering and welding is: in soldering the filler material is different from the workpiece material. so this guy is melting a aluminium rod on a aluminium engine block, wich makes it welding.
+Lex Breijs It's aluminum brazing. I don't why they call it welding, other than it's a marketing thing. The rods are most likely a combination of tin, zinc, and aluminum, and maybe a couple other things. That being said, these rods do work well I've found.
This is soldering. Does anyone really believe that the "fix" in the combustion chamber will last? The temperature inside the chamber probably would remelt the "fix" and it would disappear onto your rings, valves, runners, pistons,....
