Wow, that looks sooo easy (y)

And it works as I found out..repaired a snapped off lug on a friends gearbox for him..:slayer:tip here is you must use a wire brush with stainless steel wires ..you must make sure you clean off all oxidation or it wont work..(y)
 
no penetration, maybe ok for hole filling, wouldn't trust it for structural work though

Clearly what you know about welding can be printed on a postage stamp..:p

Phil, using steel brushes on aluminium will eventually cause corrosion in the parent metal after welding (due to galvanic corrosion and inclusion of stainless steel fragments in the aluminium.

The other resaon is surface abrasion (eg using it on a sealing face of a cylinder head is likely to contribute to premature seal failure), but thats and advantage in your case

Brass is OK, but steel brushes of any sort are a bad idea.

When I did my training we always used s/s brushes then for cleaning all oxidation from the work area ..mind you back in those days we used T.I.G for most of the fine work and M.I.G for all heavy fabrication work..at the time of doing the repair to my mates gearbox I just went by what they said on the site..he paid for all the rods and brushes anyway and I just provided the labour..and for sludgey ..listen to the vid again or read the right up..it does weld aluminium..(y)
 
yes it looks quite impressive on the vid, but it really is brazing.its a far easier process than tig welding which is real alu welding, used for full pen welds etc.
they make it look quite strong, but being a cynical old git i would have to try it myself:D..i was a coded welder from late 70,s right through to 2000[on&off]
arc eyes was not very nice:eek:
 
ah, just watched the video now :D

i remember Jordan used this stuff on a set of off-road suspension forks to weld a broken brake bracket, that is still working fine 6 months later as far as i know (y)

good tackle. Friggin fiddly to use though! Before he got used to it, it was either not enough heat, or so much heat that it liquidizes the workpiece....
