I got to see this demoed at the convention the other day it is AMAZING stuff. i am going to get mine in a few days and do some body repairs. Im getting the rods for steel and the ones in the video. Really impressed with it. http://www.youtube.com/watch?v=N-cv3R4fWZc
I saw those guys at carlisle soldering aluminum cans together with that stuff... I bought a small bundle of the rods, more out of curiosity than anything else. It does work, provided you clean the surface very well and use enough heat. It's basically a high tensile strength solder... I've used it for a few things here and there, nothing structural.
Did a quick google, this was first one I found.... http://www.aluminumrepair.com/shopping/shopdisplayproducts.asp?id=10&cat=HTS-2000 James
I like the idea but, don't trust the bull. Been fooled before. I have a cellar full of rods and even a torch set to weld aluminum. I don't own a tig so I keep grasping at strawes
they set up around here at all the swap meets but dont know anyone who has tried it ,have to do some checking
Round Rock welding supply here in town carries some of that stuff. Been wanting to buy some for a while and trying it out.
personally, i'd be willing to believe their claims. I've seen this vid before, and i've also personally used some very expensive welding rod that could make a hero out of a first timer. Metalurgists have created some truly amazing alloys -high strength, combined with ease of use. The flip side is the cost of them. I've used the Super 600 (newer version of the old Super Missile rods) rod when arc welding steering forgings- spendy stuff, but it'll weld Heaven to Hell and fix the crack of dawn... -rick
Also look for Aladdin 3 in 1 or Durafix. They are high Zinc content brazing rods, they melt around 730 degrees and they can be pretty handy to have around, JC Whitney used to sell a much cheaper version of the same basic stuff. Buy it as cheap as you can find and practice a lot if you want to use it. It is certainly useful.
I have some of it and have used it here and there like Thunderbirdesq. It does work,although I am an experienced T.I.G. welder and prefer welding for anything structural. Just like anything, it has it's place. I bought it to use in those rare instances where welding is difficult or impractical. I've used it to repair aluminum radiator cores that leaked where the tube meets the header, and some other oddball , low heat type applications. It certainly does not replace welding,but is a nice thing to have in your bag of tricks. Just like Andy said, cleaning is of utmost importance.
i have used it in my shop for a few years. mainly for aluminum ac lines and condensors. but MUST be vey clean. works great. i used to buy it at the auto swapmeets now my local farm store carrys it. but for structural welds i would fire up the tig or mig.
I can't watch the vid, it sounds like you guys re talking about the alumalloy aluminum rods? If so, Clean Really well and they work damn good, I fixed a crack in an intake.
Like others have said,cleaning is very important. DO NOT use a wire brush that as previously been used on steel. Keep a wire brush(stainless steel) dedicated for use on aluminum.
