    I think I just saw that over on Welding Web. I am curious how to achieve that, and if it actually serves a purpose besides needing multiple passes. (i guess it is a form of multi-pass, really!)

    I'm pretty sure this is how is done..

    So you are the one that did it, I was not sure why..

    Relevant to bikes, well I can not answer that, relevant to TIG welding technics I'm all over..

    Do what you wish, but give the posting a day so some other people can collaborate and see where it goes..

    In fact show us some of you pretty welds please..

    You've got a day. What you've posted so far is IMO not on topic but if it develops into something useful, great.

    Okay Nicolai's have pretty much the best weld in the bicycle industry, at least for aluminum.

    Here are some of mine, Raw M-pire.


    The machining is also magnificent.


    I like it so much that I got another one..


    The little argon too..


    This one is not mine but still a good example..


    Show us what you got..

    My friend JP is a amazing TIG welder, but he was not even sure this was a weld, but a machine process (Reason why I start this posting)



    Thin wall steel forks with out the need of a rod.



    Oh yeah he can weld aluminum too, this bike is from 1986


    Yeah very innovative too..

    The thing about welding bicycle frames that impresses me a lot is how they can maintain their hand positioning to weld a continuous pass all the way around a tube. Start at the bottom and go all the way up over the top, and back around to the bottom without stopping. Would takes some serious contorting to get that off I would think. The welding itself is pretty common Tig work, but to position your body to get smoothly all the way around that tube and the jig fixture takes some skill.

    Hey;

    I'd guess those first ones are machine welded.

    Laying down a straight bead with perfect symmetry is hard enough. Doing it around a mitered tube joint is phenomenally difficult. My welds prove it!

    That first one was done by walking the cup and most likely with the aid of a welding positioner. Thats pretty much what i do all day... once you get use to walking the cup its super easy and a positioner will let you hang out at the same torch angle the whole pass making look like so.

    defcon4130 is bang on the money

    was going to say this is walking the cup , its primary purpose is to keep constant gap at the torch tip second thing is its dissallowed for certain welds (not bicycle related) at least in the UK

    this guy makes pretty welds

    personally i aint no fan of this faux stack of dimes love affair thats going on with wannabe welders , When i got certified many many years ago in aerospace there was no such thing as this make the weld pretty lark, spot welding a bike frame together with big overlapping blobs which are not fused properly? maybe not the best way to put anything together eh? the only way you are going to tell if a critical weld is sound is not by looking at it...but hey its only a bike right

    this guy has it right though

    Mostly stainless it would appear. Tends to look more like aluminum than most steels due to its convex profile to avoid cracking during cooling.

    spot welding a bike frame together with big overlapping blobs which are not fused properly? maybe not the best way to put anything together eh?
    Couldn't agree more

    I really respect Don Ferris's work. Beautiful solid welds.

    Wow amazing, thanks for sharing, so what is he making aerospace (the parts look to heavy)..??

    Does he use a fixture to spin the part or how does he do it..

    I totally confess I'm a Dime fan, but then again and not a welder or at least not a good one..

    I always liked Nicolai's welds as well, I think Devin Lenz has some beautiful welds too. I have seen his in person but not a Nicolai. The OP's weld pic is very cool though.

    I'd take Garro's untouched brazes over any tig weld hands down. Works of art.

    Pateinto i dont know what he's making , i know of a company in the USA who make turbo manifolds and inlets ,toxic fab or something, again its all stainless, i was taught to weld Ti and aluminium ,whilst many find aluminium difficult i find it easier and more forgiving than steel

    tig vs Braze........Garro already knows the answer as do a whole host of guys who used to build racing motorcycle frames

    We have a lot of local talented welders (Potts, Steelman, etc.) but I gotta admit the guys at Firefly really know their way around a weld:

    I'm new to TIG (been brazing for 18 years) but I find this too - much more comfortable TIGing with aluminium than I am with steel. It's the larger puddle size I think, more like fillet brazing.
