Welding aluminium Part 2

[drheadshot12]

how did i get here?:P

[collectyourpayments]

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.

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!

TIG ALL THE WAY THIS STUFF IS CACK BUT VERY GOOD 4 EXTRA FINE ALLY PATCH UPS

this guy left a nice hole in that pump case at 5:00

ever try to grind aluminum? You cant very well. You need a CNC drill to cut smooth lines in it. It is nothing like steel I have found. Very hard next to steel and much lighter.

[SWREngineering]

@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.

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

[CrashFC3S]

LOL THAT IS NOT WELDING...its brazing...

[jagwermk2]

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,....

[anikidwolfy]

@jagwermk2 i was thinking the exact thing :D

[280zx2by2]

Did he really just use that gay solder shit on a cylinder head? BWAHAHAHAH!!!

[multiolay]

why not just heat it redglowing and then melt the rod???

[sleak112]

@multiolay Since when does aluminum get red?

[runforurlife100]

isn't this pretty much just brazing?

[dogg502]

Wow I would never trust that!

[SthealthRaider]

i would use tig weld

[Revco91]

Ive 'welded' 2 bits of ally tube 30mm long, 12mm dia O/D 8mm dia I/D.

I put one length ways in a vice the other stuck above.

I put an 8mm dia steel bar through the bit of tube and tried to sheer the join.

I couldnt break it but did badly deform the ally in the vice.

[Revco91]

ive only used it to do small repairs on casings and where bolt holes have split. The video does show fixing areas round valves in a head. techno-weld have a home page .

[extremebullrider]

this durafix will not melt or deform under constant heat of combustion? I have to fix a head bolt on the side of my motorcycle head. Will this material work for that purpose? I was concerned about it melting due to the extreme temperature of the exhaust exiting the head.

[92BMW318is]

there is no way thats going to stick

[62chevrolet]

Holy Shit! This is soldering on steroids!

[exupakias]

WHAT CAS IS HE IS USING?

[Revco91]

I take it you mean Gas. It's butain, propain or butain/propain mix. The normal gas blow torch that a plumber will use.

[YZFR1mart]

@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

[SthealthRaider]

How the heck cant it like melt when the piston is fired at like 3000 rpm??

[fishkiller41]

I believe it's for aluminum and alum. alloys only.

[7olusegun]

Is 'Technoweld' the same as 'durafix'?

[7olusegun]

Please can I ask if Durafix 'welding' rods can satisfactorily weld or solder mild steel parts together?

Can Durafix also weld aluminium and mild steel together (i.e. aluminium-mild steel welding)?

[flatl1n3]

durafix doesn't stick to steel
