      I've been looking at online welding courses, and there are a bunch. Even free ones. What I personally think would be very helpful that I haven't seen, and could make yours unique, is some sort of actual interaction with a student. Like a package that includes a couple 15 min video chats.
      The problem I, and I imagine others, run into is that videos are great when everything goes perfect, but usually at some point something doesn't go perfect or I have questions. For example my weld looks substantially different than your weld even though I think I did things the exact same. Then I spend hours googling trying to figure out what happened. But I bet you could look at and probably know immediately "oh looks like you went to fast here, try slowing down a little" or whatever it may be

    I used this product several years back and made a ladder frame for lights for a saltwater aquarium. I had outstanding results. The joints were very strong, and when I sold my set-up, the rack was still going strong. This was after sitting above a 125g tank for almost 10 years. It's a great product for limited/specific uses I feel.

    I did a repair on my poll screen enclosure. The aluminum upright started to tear a hole where the door closer attaches after the door blew open in a storm. I removed the door closer bracket, applied the Alumiweld, filled the hole, ground it down even with the support, reinstalled the door closer, and that was probably seven or more years age. It is still holding and you cannot see where I did the repair and painted it over. It cannot be used for everything but it works great for some things.

    Interesting, and good to see the strength of the dual sides solder in particular. OTOH, and for the lap joint especially, I would think that having cleaned the surface very well first to minimize the oxide layer may have helped a lot with the Alumiweld.

      Lap joints are probably feasible if you wet the surface before attempting to bond, like how you typically solder electronics and wires, bond the braze to the material first, then remelt the braze to join the pieces. Proper surface prep would help a bit as well. Except there's not much you can do about the oxide layer itself during prep as the oxide layer reforms extremely quickly, which is why welding with shield gas and brazing products that interfere with the oxide layer are needed, and why you can't just 'get rid' of the oxide layer like you can with irons and steels.

    This video is really impressive. The alumaweld rod product is obviously very high quality, despite seeming like a gimmick. I do know that commercial pipe fitters, they spend the majority of their time cleaning the surfaces before soldering and brazing. Most of their labor is spent "prepping" the metal. They clean way above and beyond what is required, to get absolutely perfect soldering and brazing with no air gaps or dead spots. I was trained the same way in silver brazing. You actually clean the silver braze rod, you clean the material you're brazing, and you always use flux. I suspect that cleaning the aluminum oxide off completely, on both the rod, and the material, would lead to an even better bond. I know from experience that the number #1 problem in the home garage, is not being clean enough, and not doing the proper surface preparation on projects.

    Alumaweld is a Zinc alloy with just a little bit of Aluminum in it. It melts at a temperature substantially lower than Aluminum. I have tried it and the main problem that I have with it is that the results were inconsistent. That is one T joint I could bend 90 degrees without failure but the next one would fail before I even bent it 45 degrees. To be fair, this was my first time using it. My recommendation is that if you have a MIG welder, get a spool of .030" E5356 and use an .035" contact tip and you will get much better and more consistent results. Keep your MIG gun cable as straight as possible and use just enough tension to feed the wire. And don't forget, it is DCEP and about 20 CFH Argon. As far as the Alumaweld goes, I would use it on thin parts that need a small repair. There are also other aluminum brazing rods that have a flux core. For these, try Lucas-Milhaupt and Harris.

    I tried working with those rods and similar rods. The problem is the amount of heat that needed to be applied would remove any temper the aluminum had. The whole piece would lose stiffness after it cooled, and couldn't resist bending before the heat was applied.
    The temperature at which aluminum starts to lose its tempering is about the same as the melting point of the rod.

    The best way to use those rods is to clean the aluminum with a stainless steel brush and clean it with a solvant. Then, when you want something very strong (relative) you coat both parts with a thin layer of the filler. you then join the parts together and reflow the filler and add as required. When done right, it IS actually a strong solder.

    I used something similar to build antennas with aluminum arrow shafts about 25 years ago. It didn't weather well and was awfully brittle. The stuff I used was almost pure Zinc with a few percent Aluminum added. I see varying amounts of Tin are used in Aluminum solders now. I also see some with Copper and Silver. I expect the cheap stuff is almost all Zinc and Aluminum.
    The stuff worked fine for me if I reinforced the repair with gussets or patches to reduce the load by 50 to 67%. and protected from moisture. The stuff I use wouldn't take vibration or repeated stress.

    It's not as strong as a good Tig weld, but it has its uses where the Tig would be very difficult like on a thin casting. I have repaired thin model engine crankcases (cash damaged) with this stuff many years ago and it holds up fine. The rods I had back then recommended 'scratching' the puddle with a bit of stainless wire to break the oxide film. It's useful stuff.... and easy to use... Cleaning the surfaces is of course essential...a stainless steel wire brush is the tool for that for best results....

    Oxide layer is why the instructions say rough up the area you plan to apply filler using a brass bristle brush , sand paper, or steel wool.

    I've been struggling to DIY a repair on my transmission. I accidentally broke its corner mounting bolt out sideways and the piece that broke off unfortunately penetrated through to the inside causing a transmission oil leak. I tried JB Weld first, that was an absolute disaster of a failure. Even three weeks later the JB Weld was still soft enough to deform with my fingernail and it peeled off like rubber. Today I cleaned it all back up and tried Alumiweld hoping for a better repair that would at least hold up enough for me to get the car back on the road. Nope. I spent nearly 30 minutes heating the transmission case and used up almost an entire stick of the Alumiweld sealing and reinforcing the crack. Then I spent another hour or so filing it down at the mating surface and tapping the bolt hole. As soon as the bolt snugged up the Alumiweld cracked, almost like it wasn't even there. I don't have the money to invest in a complete TIG setup right now. Bottom line, the Alumiweld may be ok for fresh aluminum like you see in this video but for an actual repair in the real world it is useless.

    6. Can a cheap tig that is not supposedly do aluminum be used? It seems to me that a cheap $170 Tig, any gas to protect titanium rod, 100 amps, frequency 200?, and this rod would work on large parts, where the blow torch would not. The advantage would be that you don't need to invest a ton of money into a tig and a fortune in helium. The joint hold strength should be 700 to 1400, according to project farm. Flux might increase this, or at least the wicking depth?

    I needed to repair pressure and gravity die cast vintage model aircraft engine crankcases. Most are made out of aluminium but some from die cast magnesium so a fire risk. Most are repairs needed to the engine mounting lugs which have either broken out or have been drilled over size.
    What I found with alumiweld and similar aluminium solders is that they have quite low adhesion to diecast aluminium and unsatisfactory for model aero engine crankcase repairs, so now get my aluminium crankcase repairs TIG welded with 4043 welding alloy.
    The aluminium solders I found are either based on zinc or on tin. The zinc based ones are a distinctly blue colour against the diecast aluminium and over time the zinc turns black so as well as not being strong enough is aesthetically unacceptable. The tin based ones have a better colour match but even less adhesion than the zinc based ones. Worse, on cleaning up the repair the tin based solder ends up standing proud of the surrounding aluminium so again unsuitable for a crankcase repair.
    TIG welded 4043 al. alloy works well on gravity die cast crankcases which can be milled, drilled and filed back to the original profile and are extremely strong. Never had one fail on subsequent engine test. Minimal porosity, if at all.
    Pressure diecast aluminium ALWAYS ends up with porosity, usually minor which does not affect the joint's function, but leaves an unsightly repair.
    Plan is to buy an AC TIG welder so I can weld up crankcases myself. I also plan to experiment with other alloys and other techniques to eliminate porosity in welds on diecast aluminium. Maybe have done over 1,000 hrs. with oxy acetylene welding on steel and dabbled with others TIG welding equipment, so believe I can learn TIG welding fairly quickly.
