TIG TAWK! AC Welding Aluminum

  • Published: 29 September 2019
  • Frequency? Balance? Amps?! It's time to find out exactly what Willis was talk'n about.

    If you're jumping in the deep end, I recommend starting with some of my other TIG welding videos before you get into AC. But you do you.

      Any idea why the blue sharpie markings deposited at 19:49 turned red once the welding was done at 21:28 ?

        Is tig welding titanium similar to tig on aluminum?
        Given the ac needs to "break through the oxide layer" formed by exposure to normal atmosphere, and titanium also forms an oxide layer on exposure to normal atmosphere does it behave the same? Since I haven't gotten my hip replacements yet I have no experience with it. However, what you're working with in the Turning Titanium video, the vanadium/aluminum alloy wondering if that would be just as much fun.
        Short story long, given the issues evidenced by your poor unfortunate twist drill, is it a pipe dream to machine titanium in the home shop without investing in some specialized equipment?

                  Your manner of presentation. Pace of speaking and quips are good for people with Attention Disorders. I don't know why I clicked on your video to begin with but it grabbed my attention and I watched the entire thing. Reminded that I can't TIG weld aluminum since I don't have a AC welder though.

                  That was a pretty neat trick on removing the weld at 22:30 :-D. Good way to save on practice material.

                      Interesting. Usually, the recommendation is 65/35. I do have a spoolgun for my ESAB. It takes some practice to use one properly, and at first the welds will look horrible. But after maybe three yards of practice, they should be fine. Anyway, I’d like to buy the 205 and get the ac.

                          Imma try and explain this as easy as I can with no math, you’ll also need to know what a capacitor is kind of

                          A capacitor is kinda like a 5 gallon bucket with a small hole in the side of it....

                          for DC circuits at least

                          You can dump all sorts of water in the top, scoop by scoop, bucket by bucket....this little hole in the side is gonna have a nice clean even flow until the bucket is empty

                          Long story short....(in DC circuits)...they’re used as voltage “shock absorbers” to stop crazy voltage spikes or voltage noise from blowing up your TV and setting your living room on fire etc


                          This is it
                          Capacitors in DC circuits are pretty damn boring

                          Effectively....they’re a lil battery
                          That when the input power gets all squirreley....it tides em over

                          Kinda like your savings account

                          And just like your savings account....it doesn’t last very long....but with proper planning and big math problems... we can make these capacitors last through predictable cycles of....voltage hardship

                          for DC circuits
                          That’s it
                          You’ve mastered the concept of capacitors
                          Once the capacitor is charged, or your bucket is full
                          You can expect it to sit there like an inanimate object until something cool happens

                          If you cut the power completely....it’ll slowly discharge until it runs out of juice
                          Kinda like your savings account when you get fired for too much YouTube on the job lol

                          In AC circuits....shits different
                          We don’t have positive and negative...we got this push pull nonsense

                          So, to go back to our bucket analogy....
                          Now we got a 5 gallon bucket with a hole in the side...same as before
                          But instead of water going in the top and draining out of the drain hole
                          We are also dunking this bucket into water up and down too

                          Which is a dumb and useless idea

                          And probably why you’ve never done it

                          But....people actually do hook up capacitors in AC circuits
                          And they do actually do something

                          Long story short
                          Dropping a bucket with a hole in it .....into water, will fill the bucket

                          Pulling the bucket out of the water, while also dumping water in to the top will also help keep the bucket full

                          This is a stupid idea with no practical application

                          But....in electricity
                          It shows you that an AC signal can move through a capacitor

                          But DC voltages just charge and do fuck all

                          Point I’m trying to get across
                          Capacitors are used as voltage shock absorbers for DC fuck-turations
                          But.....they let AC signals pass through no problem,
                          They can’t shock absorb AC

                          Let’s say this again slowly

                          “Capacitors stop or smooth out DC voltage fuck-tu-ations, but allow AC signals to pass just fine”


                          A capacitor is just two plates of metal, and they sandwich an insulator
                          Once one side gets enough pixies, it jumps the gap

                          I promise you, there’s a zillion fuckin videos on capacitors, how they’re made and how they capacitate....but there aren’t many about “how do I use one to download porn”

                          Aluminum rusts hardcore
                          The rust layer sticks to the aluminum and basically turns into a paint
                          A protective layer

                          We call this...dross, aluminum oxide, slag, bad shit, crud

                          Well....here’s what you’ve all been waiting for
                          The point

                          When you hook up a welder to a piece of aluminum
                          You’ve essentially made A GIANT CAPACITOR

                          You got your torch, the aluminum
                          And a layer of this rusty shit in between

                          And.....DC power gets blocked by capacitors, but AC power chooches right through

                          Sooooooo...there you go
                          Assholes, correct me in the doodily doo

                                  OK, so you can do some gas welding on aluminum. The AC cobra body is gas welded. In this case they generally use 1100 series.

                                  As to not being able to DC weld aluminum... well actually you can. You need to use a fresh stainless brush and clean the joint very well and scotchbrite your filler too followed by a wipe down with lab grade acetone. Hook up your helium bottle and start welding. Be very deliberate about feeding in the filler. Also watch out for the penetration. I have used this many times on welders that don't have the legs to weld thick aluminum sections on AC.

                                          Mr TIG did a video where he demonstrated you can weld thin aluminum on DCEP but he had to use a massive tungsten.

                                          The way it was explained to me is the heat will move in the same direction as the elctrons. Elctrons flow from negative to positive so on elctrode positive the heat is flowing into the tungsten. This is why mig is EP as the wire is being consumed so it doesn't matter about electrodes wearing as the electrode is being pushed into the puddle. I used to wonder how DC mig welded aluminum until I realised this fact and that DC is what cleans.

                                          I also just watched a few videos on aluminum TIG DCEN. They used helium which heats up the arc which burns the oxide layer off and you can lay filler into the puddle. Becuase this method has no positive the torch stays alot cooler while pumping in much more heat into the work piece.

                                                  Wonderful video. I very much appreciate your expertise and style. I'm an armature welder, and have read many books, but your explanation of balance is brilliant. But, I must disagree that the ability of AC current to break up the oxide layer does not signify intelligent design. Were that case, the oxide layer would not interfere with welding. Thank you for your video, and I look forward to others.

                                                                          -Too conservative on the amps
                                                                          -Too big of a gap between the aluminum and the tungsten (Keep it close!). This one in particular caused me to turn down the amps as a result of too much heat spread.
                                                                          Too big of a gap will also screw with your gas coverage if you are like me and use a small (5) cup to save gas. You will end up with black bird poops that didn't fuse to the aluminum.
                                                                          -Don't angle the torch! Point it directly towards the aluminum, otherwise you'll burn your filler rod before you even reach the puddle and your rod turns into poo!
                                                                          -Let the aluminum cool down after a bit of welding. If you need to fill big gaps, do so by spot welding puddles on top of eachother.

                                                                          I used to hate welding aluminum because I completely failed. Now I prefer welding aluminum over steel, mostly because I have a ton of aluminum material laying around.
                                                                          Correcting these crucial but hardly mentioned steps got me to properly start welding aluminum, up to the point where I could actually make beads and start practicing speed, filler frequency, amps and so on.

                                                                          I've probably spent as much money replacing my gas tubes over and over as I've spent actually buying the tig welder

                                                                                  I'm no welder but, based on my knowledge of passive electronic components, I would assume that the oxide layer of aluminium/aluminum creates a non-conductive layer on the metal and the electrode, oxide, and metal effectively become a capacitor. Passing DC through a capacitor charges the capacitor and, once charged, no more current can flow through it and it can't heat up. However, if you keep charging and discharging the capacitor (which is what AC does), you can keep current going through it (in alternating directions) and heat it up. That's probably why you need AC for aluminium/aluminum TIG welding. Capacitors, based on their shape, pass certain frequencies of AC better than others. So, selecting the right frequency for the shape of the piece (i.e. the shape of the electric field between the electrode and the piece and the depth of the oxide layer), should help you avoid the need for higher voltages.
