You should drill a hole right at the end of the crack, both ends. This will keep stresses from pushing the crack further

Thanks for sharing this information with us. It looks to me that you made a successful repair. I have not read all the comments here so I might be repeating one.... cracks can be stopped from propagating by drilling a hole at their leading edge.... then fill the split and the drilled hole. Keep up the Great Work !!

Mapp gas works great. One bit of advise, even though you have cracks, its best to clean the cracks as well. Use a file or grinding wheel. I found lying the Alumiweld only over the surface will lead to the pipe cracks to crack again. But you did a good job.

Probably should drill a hole at the end of the crack. I’ve welded aluminum boats with solid aluminum rod and the first time it cracked again after drilling a small hole they seem to hold up well. Also map gas works good.

The reason it took so long to reach melt temp is that vice was literally sucking all the heat away. You would have been MUCH better off to have clamped it with a pair of needle-nose vise-grips or something else with far less mass to heat up.

I'm way behind everyone who was commenting/arguing the merits of welding vs brazing vs soldering, which is stronger, lasts longer, etc, etc. My take is welding can be construed as attaching two pieces of metal together whether the base metal is puddled and fused with the other part (or with a filler rod) or, only the filler rod is puddled and adhered to the base metal. Actual definitions are needed when discussing the different techniques. It was also stated that to weld (fuse together) required electricity. That is incorrect. I blacksmith as a hobby and I forge weld steel together with heat generated with coal. The two pieces are heated to almost liquid (like a puddle) and joined together with pressure which fuses them into one piece. Flux (usually borax but could be other mediums) is used to keep the surfaces from oxidizing prior to joining. Just my take on things. I liked the video and the information presented.

Very nice video. If I may add a few comments or suggestions to your demo. I have successfully used those rods to repair many items made of aluminum or what is often called "pot metal", like the thin housing halogen light fixtures are made of, or any items like that which are usually thrown out when broken. As you started out surfaces must be clean, and I mean CLEAN. Any kind of dirt, debris, or carbon will adversely effect your repair, to the point the molten metal will not stick or even stay on the work. Stainless steel cleaning brushes are the best, depending on the size of repair the smaller tooth brush size will suffice, or if the job is bigger rotary brushes on a drill, angle head grinder, or a motor arbor works well. Control of the heat on the repair is the most critical part for a successful repair. The work or part being repaired must be hot enough to melt the rod, not the heat source melting it, but the work being repaired. Very critical part, the work must melt the rod not the heat source directly. In doing so, the repair must not be so hot that it will melt and fall away. The faster the repair is heated the better, get on it, braze, and get the heat away. Proper size and type of heat source will provide that. Also practice, Try your luck on a piece of scrap first. And Mr. Symba it will be ok.

"AlumiWeld" is a Zinc Alloy. And what you are doing is called brazing, not welding. Also, on a crack like this, I recommend that you drill out the tip of the crack. A 1/8" drill bit will usually be sufficient. There are better brazing rods than AlumiWeld. One is is Al-822 by Lucas-MilHaupt. However, it is much more expensive than AlumiWeld but will provide for a stronger joint. When brazing you should make sure that the metal is hot enough for the braze rod to melt when it contacts the metal and not from your torch flame. hth

I had some aluminum brazing rod once many years ago. It was hard to use as you had to make a puddle of the stuff and then scrub through the liquid to the base metal with a stainless steel wire brush or just a piece of stainless for the ‘ braze ‘ to bond. This newer stuff looks easier to use, like just using some lead solder

That cast iron vice is sucking the heat right out of the aluminum piece. That’s why its taking so much time to heat the aluminum. Next time use something non-metal to hold it. For example, put the aluminum in between two bricks and clamp the bricks together.

You are brazing because you are not melting the base metal. The cold vice is drawing the heat away so use ceramic tiles between repair and vice or move repair away and clamp further down. That is why you struggled to reach a good heat and that is why you melted the brazing rod instead. You should of also cut a vee or bevel in the split to hold the melted aluminum brazing rod.

Brazing is not welding. Brazing is soldering, just at a higher temperature. In a braze you don't atomically bond the filler to the base metal, in welding you do. And welding doesn't have to be only with an electrical arc. You can weld with oxy-acetylene, that's how all welding was done before the advent of arc welding.

Jake Rodgers Technically, yes, if you're going by the Webster definition. However in any industry, welding is differentiated from soldering/brazing in that welding requires both the filler and the base metal to melt.
