is this for real??

take a look at the download, very interesting

Looks very much like silver solder to me.

Can use silver solder to join most metals, and it is quite strong, provided you use the right flux and grade of silver solder.

bloomin 'ek .. if that vids for real that stufs damn strong!

Looks impressive, but the name is soooo cheesy.
$65 for some looks almost worth while but for 1lb of the stuff how much is that going to cost to ship over??

Perhaps one of our stateside members would like to do an independant review of the stuff :wink:

[PaulAmes]

Wow, that stuff looks amazing. I hate welding alloy - never get a really good join, this stuff looks the ticket.

[BassAddict]

That does look pretty damn good ! I've seen something similar looking at a classic car show near us, Tatton Park, which is on twice a year - the last couple of times I've been there's been a bloke selling stuff like that - not sure if its the same though !
Might have to have a closer look next time !!! :)

.....and it is pretty convincing in reality as well !
I´ve been using the stuff on a number of carburetor bodies and Mini gearboxes. If done properly, the welds are strong enough to carry the complete weight of an a-series/gearbox combo. The material is available under all sorts of brand names. If anyone´s interessted, I can look it up in the workshop. Cheers, Martin

[BassAddict]

Definately be interested in some of the other brand names :) !

Been looking into this type of stuff, and available in the UK is the following.

Techoweld! Yes another cheesy name.

Its available from a number of places, including Farnell where this datasheet is from http://www.farnell.com/datasheets/27086.pdf

Seems to be the same stuff. More details here http://www.techno-weld.co.uk/

Best of all the basic kit is less than a tenner. So its got to be worth a try.

[BassAddict]

I wonder if its the same as LumiWeld -

This one's abuot £12 for 5 rods - and this shop is about 5 minutes drive from work :wink: !!!

So you'll be trying it and reporting back then :wink:

No need for a tig now wahoo :lol:

Taken from another forum.

I have a classic Twin Shock Trials bike. engine was rebuilt about ten years ago, and the piston crown had sunk around the exhaust port.
As a replacement was almost completely unobtainable, and the best we could do would be find and modify an alternative to fit, a mate of mine siad he'd have a go at rebuilding the crown with aluminium weld.

I 'thought' he was going to use MIG to build back up the mtala and then polish it - no, when he'd done he'd used lumiweld.

Well, I used the thing - I didn't expect much, but thought I'd give it a try, at the very worst, Id just have to lift the barrel and fit the modified alternative piston.

And, surprisingly, its still there and going strong - took a class victory on the thing last season, so it isn't exactly treated delicately.

Is this a reccomendation?

Well, I spose it means that the stuff CAN work.

[trickey]

I can remember an artical in cars and car conversions a few years back about technoweld, Dave Walker tried it and quite liked it as I recall.

[BassAddict]

Yup - think I'll be popping in there next week then !!!!

Makes you wonder what someone will think of next!!

[BassAddict]

Still like the idea of this ultrasonic welding that aston use on the DB9's !!!

[Geehawk]

Makes you wonder what someone will think of next!!

Yeah. They'll be putting men on the moon soon :D

I talked to a mechanic friend of mine. He used one of the first generation welding rods for Aluminum. It was basically crap. He thought that this stuff (second generation) looked very interesting. I ordered some and we are going to try it out on a manifold that I have to rework. He has other work that would save him a ton of hassle in rebuilding older cars. Will post back here on the results.

[Mini1380]

Got the stuff in. After some minor trials of not getting this to work very well, a couple of phone calls were made to the company. The main point is that you have to TIN the two surfaces first. If you don't properly tin them, you will not get very good results. So far the tests are very promising. Will post more if people are interested.

Talked with another friend about this. He is into airplanes. One of his fellow airplane builders is using this stuff with great results.

I bought some lumi weld at the weekend and just had a play.

Couple of strips of 1/2" by a couple of mm ally.

Small strip "welded" to the larger strip, overlapping, by a narrow join at the end.

Bit tricky to get the hang of, but I couldn't break my first weld. Beat hell out of it, and finished up with a hammer and chisel right on the join. The strip kept breaking, but not the weld.

Good stuff for small repairs I would say, but dont expect to be making alloy catch taks etc with it :wink:

Pics in gallery..of the damage :lol:

[duck]

I used lumi weld to fill a couple of dents in my cam cover, it worked ok but the only difficult bit was the fact you have to heat the whole item up to the temp lumi weld needs to melt.

I ended up with the cam cover on the gas cooker with all 4 rings going to get the whole thing hot enough, had to wait for the missus to go out first though :D

The lumi weld bits polished up better than the actual cam cover.

[Mini1380]

Just thought that I would bring this back up since there was another thread on this.

My Mechanic friend played and played with this. He could never get it to work the way they say it should. While visiting a car show he met someone selling this welding equipment that he had. He was able to get a manual on the machine and figured out what is problem with the machine was. Now he has both a MIG and TIG machine and doesn't need the Alumiweld stuff anymore.

I am not saying that the stuff doesn't work, but it probably depends a bit on the experience of the welder and the quality of the material that you are working with.
