Non-dipping TIG technique?

admin

I imagine this has probably been discussed before, but I was unable to come up with any threads while searching.   I just stumbled across this .  The filler rod isn't dipped, instead, the pool is pushed into the tip of the rod.  What is your opinion of this?  Crutch?  Sloppy technique?  Cheating?  It looks easier to learn, if nothing else.  Just curious, thanks.__David Hillman

Reply:I call it 'Lay Rod', do it steel, Al and SS, very useful if the heat's cranked up, the joint is configured to allow this--- and one needs to scoot along. Can be considerably fasterthan dip-dip-dip"What is your opinion of this? Crutch?-no-Sloppy technique?-noCheating?-no It looks easier to learn, if nothing else. Just curious, thanks. "It's more difficult to do than normal dip--watch undercut, good edge wetting, total puddle action,bead configuration--try it. Very easy to have problems with some or all of the above-quickly.It's not 'difficult' for guys that have a 'little bit' of bench time.For high amp, low pulse rate 3-5 cps--on SS, AL and steel, (I call High Energy Pulsing)--I have to use lay rod to maintain the travel speed required--which would be a good double of what you see in that Brazilian video. Benefit is minimum heat input, minimum distortion--for whatever that's worth.Blackbird

Reply:it s not hard, no harder than dipping at a steady pace you still need to feed filleri use it for running edges on SSprops  keeps the build up down so i don't have to grind off as muchworks for meidealarc 250/250 ac-dc tigidealarc 250/250 ac-dc tig #2 used for sticklincoln sp100hh125dual arbor grinder polisher30 yrs of hand tools52 pitch blocks 6p-26prake gauge -pitch gaugeG&D prop repair 918-207-6938Hulbert,okla 74441

Reply:I have never really thought about it, but thats how I tig weld alot, never really noticed I was doing it till a couple weeks ago when someone asked my why I was doing it that way.  I had no answer, I just do what works at the time, or "feels" right in the situation?  I don't claim to know very much about any of this stuff, but have done quite a bit of welding of different things and different techniques.  Here's some pics of some  titanium pipe welding where the question was asked.  After that I ran a little bead on some TI strap and realized I was doing just that, laying the rod and just catching it with the leading edge of the puddle.

Reply:It depends what you're doing, but its a bonafide method of adding filler material.The guy in the video isn't really that great at it, he lets the filler rod ball up on him quite a bit (incorrect torch angle or not feeding the wire in quick enough), and he's got the heat a bit low, as he should really be travelling alot quicker. Normally (but not always) used when walking the cup, giving you very consistant, uniform beads. Another reason that people, (myself included) like to use this method on stainless, apart from the already mentioned heat issue, is that you have zero chance of contaminating/oxidising the filler rod whilst welding.
Reply:I learned to create a better looking bead with Ox/Acetylene welding in HS.  Haven't done much since, but it sure worked quick & easy.MarkI haven't always been a nurse........Craftsman 12"x36" LatheEnco G-30B MillHobart Handler 175Lincoln WeldandPower 225 AC/DC G-7 CV/CCAdd a Foot Pedal to a Harbor Freight Chicago Electric 165A DC TIG PapaLion's Gate Build
Reply:Check out Jodies vid at Welding Tip and tricks to see it in action.  He is doing 6G with a 3/32 gap and using lay wire to fill the root pass.  Never pulls a keyhole and fills thee groove nicely.BobI'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys?  Trade?
