Bernzomatic AL3 Aluminum Brazing/Welding Rods with 12-Inch Rods of Working Temperature 720-750 Degrees, 2-Piece

Good 👍

I was looking for a product to 'weld' two thin walled aluminium tubes together, I was always a little too heavy handed with my tig welder, I have a great deal of experience with plumbers soldering and brazing. I followed the instructions and tutorials on youtube. Using a plumbers torch, I heated the Ali til the Bernzomatic rods melted with the heat from the ali, once you have filled the area with the rod, I found that I could flow the area better by wiping a tungsten mig electrode through the welded seem, you must keep the weld area hot, ends up looking like a soldered joint. Very happy

great rids for quick repairs, easy to use, melt and flow nicely.

used this to braze some aluminum pieces together. worked very well however it does take practice and patience. My tig skills are not the best but I can solder so thought to give this a try. very satisfied with this product. I found that it does take a lot of heat on the metal to get it going, and like other reviews have said its necessary to heat the metal and melt the rod into it. It does help to use a tig tungsten to direct the puddle as it does not flow to rapidly which is actually good as it helps fill holes. Best procedure is to get the parts as hot as you can and use the rod very sparingly. this will give the best flow and get just enough rod around the parts to form a nice bead which then requires less clean up. then wait a while for everything to cool down. I had to remind myself several times that welding gloves are not tongs.

Works really well for what it is. I used this to repair a puncture hole on an older aluminum bicycle frame, and I was initially having issues using a smaller torch, I couldn't get the product to melt on the frame. I picked up a bigger handheld blow torch from Harbor Freight, still using regular green tank propane and was working within minutes. The sticks are fairly easy to work with, as long as you don't let it run and don't apply heat directly to the stick. I have some welding experience from working in a steel yard, but none in brazing or aluminum welding and this product was very easy to use for a first time user. I just watched a few YouTube videos and dove right in. I was able to span a hole almost an inch in diameter by using a circular technique, and I built up the product enough to where I was able to grind and sand it smooth afterwards. I just had to be careful of overheating the existing product I had laid down as I was building it up, or else it would run or drip. The size of the torch was really paramount, as was heating the area surrounding your work. You would never have known there was a big puncture hole in my bike frame at one point, unless you stripped the paint off and saw the difference in colors of aluminum. Highly recommended for small repairs, and saved me from going to an aluminum welder or bike repair shop.
