Quite likely. It cannot be a weld in the true sense of fusing the parent metal.

They have adverts on Instagram for this stuff all the time, which’ll tell you enough about who their target audience is. If you ever see the comments on there it’s always got a few people who know what they’re talking about saying it’s a load of nonsense and that it’s just solder.

Handy stuff for sticking two bits of Ally together....... apparently. :eusa-pray: :eusa-pray:

low temp aluminium "welding" has been around for years, it's ok, but I wouldn't put my life in the hands of it, at most I'd use it for non structural stuff, which it's absolutely fine for.

it isn't a weld, it's a bond similar to solder or brazing.

this is the stuff I've used in the past, it did the job I needed at the time when I didn't have access to the welding set.

Be wary a lot of these adverts are a con, a friend bought some rods & they simply didn’t work, he raised a complaint about them with eBay or Amazon I can’t remember which but the supplier got off on a technicality so he lost his money.
As usual if it looks too good to be true it usually is.

...it isn't a weld, it's a bond similar to solder or brazing...

That said, it's worth mentioning that modern adhesives are incredibly powerful :shock:

I remember once when Clarkeson (infamous for TG on TV) was giving an old Hawker Hunter a close examination for one of his programmes and he came across a repair that had been done to the leading edge ( I think) of a wing. The brownish, smear of adhesive was in fact 'old skool' Araldite; bear mind this was a high performance fighter jet (I think Rog M might have done a few hours in one ) capable of speeds up to or exceeding the speed of sound(?)

Also, when I was doing my two decade long sentence at the 'chalk face' I decided to create a disc sander by gluing on an aluminium face plate to a lathe spindle from a redundant Union Graduate (rubbish lathe, we never used them ) Again, I used slow setting, 'old skool' Arladite and glued it onto the spindle. Some time later, I found that it wasn't quite running true so I decided to try :eusa-whistle: and remove it. I sauntered over to the metalwork forge and selected a very large, very heavy forge hammer and proceeded to give said faceplate several 'haymakers' with the hammer, in the hope (forlorn as it happened) that the bond would break. Fat chance; as far as I know the faceplate is still glued to the spindle on the Graduate - Rob

assuming that the substrate that is being bonded is clean of contamination such that the adhesive can bond to it and that you use an appropriate glue (prittstick doesn't work on metal) then a glued joint can be incredibly strong. TVR did it for years.

brazing and soldering have their place too.

I have done a bit of welding and brazing so I understand the concepts.
I knew it was a con, but how do they get away with it? :eusa-think:

I have seen a demo first hand of the ally welding/soldering and you can't get the joint apart even with a hammer.

I have those, used them to fix the hasp to the gate for the garden so the dog could escape. Then found out he is skinny enough to fit in the gaps of the fence ho hum

very good though, I was quit impressed and bought 3 more packets to have around. you do want MAPP gas tho Very handy.

@woodbloke regarding modern glues, i remember When Chris Patten was sent to Hong Kong as the Gov, he flew out of Brize and i remember the riggers working on the Timmy tristar that was taking him. They ran a full length of of black nasty down the leading edge of the wing as it had a crack in it and they fixed it when it got back. i also remember it being used on the nose of a couple of buccaneers as ack ack had damaged them over the road to Basra from Kuwait City and they didn't have any spares

That's what it looks like to me.

Same as Pete I've watched the demos a couple of times when at the Harrogate show and it was impressive when he bashed the joints around and couldn't break them, if I remember he made sure the "solder" flowed right through the joint.
I was tempted but didn't buy then found the guy wasn't at Harrogate last year so I bought a dozen of the cheapos from China at the end of last year and though have only used a couple of times on Alloy they did work. I'd qualify that by saying my welding and soldering skills are woeful and I found it essential to keep cleaning the materials but I've joined alloy and filled a couple of smallish holes successfully.

It's a safe bet the proper stuff is much better but for the price these imo were worth the less than £5 I spent.

...ran a full length of of black nasty down the leading edge of the wing...

That's a blast from my past! Incredibly sticky, really horrible duct tape :lol: I came across it a couple of times in the MoD a few years back. What it wouldn't stick ain't worth knowing :lol:- Rob

I have used that type of solder to repair a crack in the outer shell of an electric motor. Of cause I had to press out the stator first to avoid damaging the stator windings.
Anyway it did work but it was a solder not welding.
