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

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

Good 👍

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

I bought these to repair an aluminum radiator and they worked great. Saved me from having to replace it.

Does not work as stated. Very disappointing to buy and results are poor. I’m not a welder but a diy with various skills and I could not work either this.

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.
