roy53 Posted May 11, 2020 Report Share Posted May 11, 2020 Has anyone tried Solution Welding flux cored rods . looks as though it could be very useful in the video Quote Link to post Share on other sites
stuart Posted May 11, 2020 Report Share Posted May 11, 2020 If you mean for arc welding you would need to be very skilled to be able to use it on panel work. Stuart. Quote Link to post Share on other sites
roy53 Posted May 11, 2020 Author Report Share Posted May 11, 2020 Not really, it was something that popped up whilst doing a search. It had a video along with it which showed that you heated up the metal or alli and this product melted along the join making what they say is a very strong joint.

ed_h Posted May 11, 2020 Report Share Posted May 11, 2020 Sounds more like soldering than welding. Ed Quote Link to post Share on other sites
stillp Posted May 11, 2020 Report Share Posted May 11, 2020 If it's the advert I've seen, then it's for aluminium alloys only. Pete Quote Link to post Share on other sites
Steves_TR6 Posted May 12, 2020 Report Share Posted May 12, 2020 I used those (Or something very similar) to construct a battery box out of sheet aluminium, they worked very well and the result was strong enough steve Quote Link to post Share on other sites
RogerH Posted May 12, 2020 Report Share Posted May 12, 2020 There was a thread a few weeks ago. Something similar to this was shown Roger Quote Link to post Share on other sites
MikeF Posted May 12, 2020 Report Share Posted May 12, 2020 (edited) The video shows the resulting bond is a braze, with a very clever preparatory process to get temperatures down and not need protective atmosphere. It appeals to me for its ingenuity. It's very neat. That's the theory. In practice the key would be to get the first oxide bonding done and then satisfactorily working through the oxide in bond area with the pick to form an intermetallic. Probably OK for seams on flat surfaces as demonstrated , concern would be working on irregular surfaces. - might need some practice! If ultimate strength is not an issue you can do something similar with lead free plumbers solder. Just use the solder in the same way as in the video. Does require skill, its what tinkers used to do to mend holes in aluminium pans! Mike Edited May 12, 2020 by MikeF Quote Link to post Share on other sites
RogerH Posted May 12, 2020 Report Share Posted May 12, 2020 There is another similar product that Stuart posted on here very recently. They have simplified the process. Assemble your joint . Scratch the surfaces, heat, apply the stuff. The demo's work very well at the shows. Haven't tried it in real life. Quite expensive (£30/Mtr). Roger Quote Link to post Share on other sites

Roger The guy that does my machining has been quite impressed with it, the one I have was a Snapon kit though Im not sure that they supply it anymore. Stuart. Quote Link to post Share on other sites

Roger Is that the Swedish guy - Anders something? I bought some from him at a woodworking show last year, it was £20 and his "metre" was mweasured by standing on the end of the reel of magic wire then lifting it to his head height and cutting it. "There you are, a Swedish metre". When I'm feeling brave enough I plan to solder a piece in to replace a gap in my front grille, at the moment it's filled with a bit of stainless steel held on with a couple of tiny self-tappers.

RobH Posted May 12, 2020 Report Share Posted May 12, 2020 It does work - but be careful. If the thing you are fixing is small/thin it is easy to overheat the lot even with a propane torch, in which case you have a melted lump of aluminium........ On the other hand large and thick pieces just never get hot enough as they are a good heat-sinks. Quote Link to post Share on other sites
ed_h Posted May 12, 2020 Report Share Posted May 12, 2020 I've used This type of product, and it is trickier than implied, especially on small or thin parts, as mentioned. One issue is that the molten solder actually dissolves the aluminum, so thin sections can actually disappear. Ed Quote Link to post Share on other sites
