TIG Filler add speed

admin

Seeing as how theres no such thing as a stupid question , and its 12:30 AM here .. Lets try ..   When you are welding with TIG under normal , proper conditions, can filler be added to fast to the weld pool ?  If the answer is no.Then next one is ... lets say you are welding .250" steel with 130 amps. ( cause thats all you have... ) so you dwell a little longer .. to help heat up thesteel  a little ... then start moving along and adding filler ... think it might be possible to move along too quickly and cooling the pool / steel with the filler?Hope that all made sense? I do realize with the correct equipment this is probably a non-issue. But curious what you all think about it.. Randy
Reply:It is very possible to add filler metal to a Tig puddle too quickly.  The result is a cold and lumpy looking weld.  You really don't need to add much filler metal at all.  Basically, once you get your puddle going just dip the filler rod, move the torch forward (bringing the puddle forward) dip the filler rod, and continue on in this manner.  The further down the joint that you go, the more your base metal will warm up and the faster you will want to go.  I don't know if this makes sense, being as is is 2am but I hope that it helps.
Reply:Yes .. it made sense ... and I do what you said on the speeding up .. But then there too .. it depends ..  cause like I say .. I'm laying a bead across a .250" piece of steel with a 130 A TIG .. then I want some heating ..  but believe it or not ... by the time I get to the other side of a 4" piece of steel , its almost heating up too much .. and I do have to speed up a little bit .. but .. as I go across ... and add filler .. could I assume that adding the filler is cooling things a little bit too ??  Heres a question for you .. you add the filler and move the puddle forward... is there any pause ( this would be before things heat up )  from the time you add filler till the time you move the puddle forward .??Also .. there are flat / rectangle shaped fillers I noticed .. not in the steel variety , but I did see some today .. is there areason for it to be that shape when its say .. silver / bronze / copper filler ??Last edited by Lanmanb4; 08-18-2006 at 10:43 AM.
Reply:come to North Attleboro in Oct...i'll show ya.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:So what kinds of things do you have planned out for us? and unofficial "lesson plan" ??
Reply:Lanman,The only TIG filler wire I've ever seen is round. Many different diameters, but round. Were you looking at brazing filler? "Silver solder"- BCUP and BAg - rods may be flat or round.Weldtek
Reply:uhmm  I'll get some particulars next time I am at that welding supply store.
