Has Anyone of you guys ever tryed to repair some aluminum or cast iron or steel of a kind with these brazing HTS 2000 rods ? http://www.aluminumrepair.com/ Martinius.
Martinius, as an aluminum welder, I have to say I'm pretty suspicious. Anything that says it can go over oily areas or such sounds rather unlikely. With most things like this, it probably can't hurt to try, as long as the cost isn't too much, as the worst that will happen is it will fall off, then you can try welding it. I won't say it ain't possible, but I'd take their claims with a grain of salt. For brazing cast iron, a regular uncoated bronze rod with cast iron brazing flux works quite well applied with an acetylene torch. The flame ususally tends to heat the whole piece up gradually, allowing it to all expand and not crack. Post heating after the braze weld is made to let it cool a bit slower and evenly helps. As for aluminum, though...hard to beat cleaning it up, veeing it out, and tigging a new layer of aluminum back in. Bring it on over, I'll fix it for ya...
TIG welding aluminum a better way to go! Thanks for the reply Spika and your information. I`ll presume that its is better to TIG weld the aluminum frame i have ? Martinius
Hi Martinius, i´m with Spika on this, we also do some Aluminum welding in our company; we use a 200A Castolin Tig welder, and i think, that´s the way to go. It really depends on the piece you want to repair, if it´s something as thin as 1mm or less, tig welding is pretty tough, as this gives you a hard time, not to overheat and melt the whole thing... I´ve been to a vintage car show a while ago, and there was a guy selling some kind of Aluminum brazing rod, he repaired things like broken carburetor bowls and such. This might be an adequate solution, as these parts are not 100% Aluminum. Good luck with your repair
