Bernzomatic AL3 aluminium solderen/lassen staven met 12-inch staven van werktemperatuur 720-750 graden, 2 stuks

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

used to repair a flawed by design hot end on my 3d printer. its been holding up at 263c without issue so far. i know its not what its for but it works and works well.

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

Wow, I bought a few different brazing rods including these brand name and the no-name. Wow wow wow what a difference!!! The photo of the lumpy metal is the absolute best I could do with the no-name rods that were bought in a pack of 20. The smoother welds were done with the Benzomatic. It flowed like solder into the aluminum, even filling a big gap in the boat.Note also that the no-name rods are very thin, the benzomatic probably has about double the volume per rod. That said, the 2-pack of 12 inch long Benzomatic rods only did about 9 inches of welding (granted, that was a big gap to fill) but they do go fast. I am going to need probably 5 packs to fix this boat.I did poke and pry at the weld when done, couldn't get it to budge.This was the FIRST EVER attempt at brazing aluminum.I used a braided wire wheel to scarify the aluminum and a high-temperature MAP like torch to get it good and hot.

I come from a sheet metal, iron work, welding background. Did some copper brazing with the HVAC service guys with my company back in the day. Also never welded aluminum, always heard it was difficult as it doesn't change color when hot, usually just disintegrates.Had an issue where the welded hinge on my fence broke, likely due to overheat from the weld. Well, haven't welded in over 20 years and don't own the machines anymore, so I looked this up and watched a youtube vid about it. Well the guy was right, just need to wire wheel the oxide off and it's ready to braze. The guy said you can use propane, and here's where I disagree. Sat there 10 minutes heating the thing, still couldn't get it hot enough. Used a benzomatic mapp/oxy kit and did a great job. I added a pic for your review, the area brazed is to the left of the weld, so I did not get a before pick, but you'd be impressed of the difference as the whole thing was cracked and broke off. So I am a beleiver and will buy again if I have any aluminum work in the future.
