  • Extremely clean looking TIG welds???? Picture

    Can someone explain what technique is used to produce this look on a TIG weld? I have been tig welding for 20+ years (mostly stainless and aluminum). But, I have never had a cause to tig mild steel much. Is it a special filler rod? Is it a helium/argon mix shielding gas?



    I really like these welds from an aesthetic point of view.

    Looks like MIG to me.....with a good setup....

        Those are TIG welds. The "Stack of Dimes". It has been discussed on this and other forums many times in the past, do a search.
        Obviously, I'm just a hack-artist, you shouldn't be listening to anything I say .....

            You could be right...

            I have seen pulsed MIG with a good operator that looked like stacked dimes TIG....

            Could be either...

            Does look like stainless steel though..from the colors in the pic..

            and from the way the color of the HAZ looks and the beginning and end of the beads

            am going to guess TIG...

            Small pic.. tough to tell.......

              It is most definitely tig, the technique is to dab filler and move forward and repeat, pretty straightforward. It's tough to say whether the parts are mild steel or stainless. The gold color on the bead means the shielding gas got great coverage and the weld wasn't too hot.

                I agree, It's definitely TIG welded and I'm 99% sure it's mild steel base metal. I'm just not too sure about the filler metal. I frequently weld mild steel pieces with stainless filler because there is far less spitting and porosity when my foot gets too heavy.

                I'm thinking it's more than just dabbing the filler. I think it may require throttling back on the pedal for ea. "dime". I can dab perfectly in aluminum and stainless but never had much success with mild steel. I've never had luck making welds near this clean.

                  pretty easy to achieve that even spacing with "Pulsed TIG" using a machine like a Dynasty with built in pulsing capability... lots of machines out there these days that can pulse.... getting pretty common.. sure beats pumping the pedal..,,,,,

                      I can explain it. The guy is bad a** with a torch. Tig is my thing. I can weld any of the processes-but I live for tig! Those welds are awesome. I enlarged them and still can't find any start-stop points. Awesome! Looks like stainless filler on carbon. Hats off to whoever laid those beads!

                        You shouldn't be pumping the pedal while tig welding! Those welds are achievable with standard tig welding techniques and a skilled operator, just being very consistent.

                          What about the possibility that it was done robotically with TIG and a cold wire feeder?

                              Well................

                              I would not go quite that far...

                              Some guys prefer to pump the pedal...

                              John Marcella is one of them... and he seems to get by..

                              I would rather think that the correctness of technique is more determined by the results than anything else....
