Question:

How strong are welds using "brazing / welding" rods for aluminum with a propane torch?

I was thinking about trying to build a bike frame from aluminum tubing and joining tubes with these rodsAnd while the material itself seems quite strong, I would question how well it bonds to the aluminum itselfSome common names of the aluminum rods are Alumaloy, Dura fix, HTS-2000, Muggy weld, Alladin to name a fewSo for anyone who has used any of these, how well does it bond with the metal that you are welding? I'm only 160lbs and this would be a road bike, so besides the occasional pot hole, there won't be to much stress on the frameI would of course do strength tests beforehand, if I did decided to build a frame using these rodsBut, before I waste time and money, I thought I would ask a few people with some experience using these rodsHow well have they worked for you? Which did you use? What did you weld? Do you believe welds would be strong enough for a bike frame (considering everything is done properly)? Any information would be great, thanks in advance!

Answer:

you can just lay the knit throw on top of fabric good sides together then sew around edges except for about 2 feet on one sideonce you are done turn the throw inside outthen you hand sew the part that is leftwhat you need to know is that knit stretches out so it may get bigger than the back over time.
I knew somebody that used this stuff to fix a machinery partHe said it worked, but he didn't consider it a high-strength repair like welding would produceHe considered it more of a soldered joint than a weldBased on that report, I never used itSometimes it's just easier to learn from others, so I'm glad you're checking on that hereI'd have to vote no, too.
