  • How do you all feel about constructive criticism?

    1/4" mild steel
    1/16" 2% Thoriated Tungsten @ 3mm protrusion
    #5 cup
    120A, but with a pedal
    Argon with a flow of 20
    DC, HF, RMT STD
    Mating surfaces sanded shiny on outer corner, no prep on inner corner.

    You're looking at my first attempt to join two pieces using TIG. That's an ugly result, if I do say so myself. But there seems to be decent penatration, little brown soot or white chalky fuzz. What can you tell me I did wrong? What can I do better? Call me grasshopper...

    Grasshopper...too small of tungsten, too slow of travel speed, uneven filler metal feed, uneven travel speed...torch angle and arc length not good too I'm going to guess....<br />
    <br />
    But for first weld...grasshopper...you join the metal...so practice! <br />
    <br />
    Wax on!!! Wax off!!!

      Ok seriously...1/4" steel, I would be using at least 3/32" if not 1/8" tungsten and comparable filler metal. When your weld is all gray like that, you're most likely cooking it. It's mild steel, so at the end of the day, if you leave it along to cool and not quench it in water, it'll go back to being mild steel. I doubt it'll break, if that counts for anything. <br />
      <br />
      What you need to do is pad some beads. Just run bead after bead, both ways, switching torch hands, overlapping each bead by about half. You'll figure it out. You'll get all the help you need here too. Just don't have too thin of skin. <br />
      <br />
      I bet there will be all sorts of links posted here for reassures that will be of much help to you in your endeavor to tig weld mo bettah.

        I Agree

        You will develop your rhythm with practice.... use music as a metronome to help get the beat of it.....

        Crank up some Clapton..... Dire Straits....Cars..... Or..???. (Your Preference)....

        AND..... Practice...practice...practice.....

        Kinda like dancing.... dip...move...dip...move...dip..................... .and so on....


        ALSO.... worth your while to revisit the stuff listed below

          Says Aluminum but most techniques illustrated are useful for all TIG.... you just have to move much faster for Aluminum

          TIG Welding Aluminum Basics.... 1... 2....3... & .. 4


          Andy Weyenberg, motorsports marketing manager, Miller Electric Mfg. Co. ( http://www.millerwelds.com ), discusses aluminum TIG welding basics. The first step to working with aluminum: master positioning of the torch and hand.

                I am reading and watching all you sent. I need to run-run-run left to right to perfect the timing and separate my hand movements. I also can't yet comprehend how setup impacts the weld. So I switched to 1/8" electrode with 1/2" cup and produced this. I tried to keep it moving without overcooking. Now I'll practice as you have advised. Not sure if any are curious so I posted anyway. Thanks for the instruction! I'll let you know when I'm perfect. :-)

                    OFF TOPIC.....................

                    I went to HS.... with a Lance Martin in Deerfield, IL many years ago (1966-70)

                    any connection...????.

                      Use 3/32" tungsten , 1/8" is too big about 125 -140 amps, 15-18 CFM and grind your metal clean.......get into the habit of keeping your metal clean , including wiping down the weld zone with acetone and..........practice, practice, practice............takes years to become good on all metals.

                        I am amazed at how many Lance Martins are out there. I'm not knowingly related to any other Lances. I grew up in St. Louis near the airport. Thanks for the guidance and inspiration.

                          Weell, Not bad at all. The way I tought my guys was they weld it together, I try to break it

                          Always fun.

                          Anyways, seems like you got it together pretty good, steel is definetley getting overcooked, need to move faster like Ryan and H80N mentioned and just keep practicing. Aluminum gets you into the habbit of moving really fast so might be worth it to try that as well.

                          The reason aluminum helps you move faster is because, when you don't, it droops and either blows through OR in my first case, drops onto your leg as a charring hot piece of white destruction and that hurts, after that. Keep my leg away from the metal and I move fast.

                          Other than that, weave it, right left right left, nice Z shapes almost or C shapes to fuse both sides. But really, just a matter of practice. If you are inside, I would set my argon to 15, not 20. You really don't need 20 and its just gonna cost you in the long run.

                          Next time you buy electrodes, buy the E3's purple band (H80N is going to argue with me on this ), they work for both AC and DC on any metal so if you wanna flip in and out of AC/DC from Alum/Steels then those will go both ways without you needing to keep 2 different types on the shelf.
                          if there's a welder, there's a way

                            As far as I can see.... the E3/Tri-Mix tungstens are more a marketing gimmick than anything else

                            IF....I could see any advantage... I would gladly spend the premium for he E33...

                            BUT I DON'T..... so why spend extra to no avail....??

                            Maybe the E3 work better in Transformer machines... But ...in my experience...they are sure not the hot tip in inverters like the Dynasty
