Tig route weld on 2" pipe

admin

I just finished my 12 weeks welder operator course at Advanced Welding Tech. Anyways I picked up a job 4weeks before my course finished and started TIG welding miniture pressure vessels. (Mild steel, Copper/nickel, and Stainless).This is my first try on a rotator. After watching the big boys and getting sick of tack welding (I'm stuck tacking for a bit), I decided to give the older rotator a go. I'm just manualy feeding filler rods free handing on a rotator.2" Mildsteel pipe.http://img.photobucket.com/albums/v2...77/weld001.jpghttp://img.photobucket.com/albums/v2...77/weld002.jpgWhen I get time I'll try it again with alittle more wire and say 20 more amps. I had alittle suck back on the inside. What do you think?
Reply:looks pretty nice.  good job therechris
Reply:More heat sounds like a good idea - you can lower the size of your HAZ if you hit it hotter and faster (and your boss will like the productivity if you can do it defect-free).I think that it looks good for a start, but you'll really want to concentrate on the wash-in of the weld legs; sounds like you're aware of that already though.Good start for sure!MR

Reply:Ok Gyro, I'm more than a little drunk right now but heres why i said they weren't TIG welds (and thank you but I'm aware of what TIG means)  I've never heard of nor seen any TIG work that has any slag on the weld, such as you can clearly see on the edges of the weld in the pics that you posted.  And the way that your puddle froze in those pics is like no TIG work I've ever seen.  Looks far more like wirefeed to me.  Are you sure you posted the right pics?   anyway, I'm on Molson Ex and DuMaurier Kings, Cheers.
Reply:Reaper, pull your head outta your azz.  Thats not slag.  Its silicon and yeah tig can give that no differnt than mig.  It dont mean squat.  Some pppl in here are just shet for brains.  Gotta come on here, "oh im soo drunk..." blah freakin blah!!   For one thing nobody gives a rats azz what you drank, or your stupid level at the moment.  Nobody cares.  And more importantly nobody gives a dam about your opinion cause its negative.  Take your dam negative attidude and shove it.  We dont need it.  As far as all else, I still maintain there is nothing "UN-TIG-like" about that weld.  I will agree looks more lke mig to me, but then I dont reckon you been around many good tig welders, Ive known plnty to make welds lookin like  that.  Turn up the amps and youll see.   So go on tuck your tail 'tween yer legs cause youve lost this battle.  GAME OVER.  GOOD BYECHRIS
Reply:Damn right, Redneck!If you're keeping a constantly-fed weld pool in TIG, it'll look likea MIG weld.  This is the way TIG is intended to be done, and it takes a hell of a steady hand and a good eye for when the puddle is depleting JUST far enough to need a feed.  Stacking the dimes LOOKS incredible, I'll give it that - and I admit that I like to do it now and again too, for fun - but if something's just GOTTA hold I'm all about a constant puddle instead of the puddle-add rod/freeze/move-new puddle approach that will stack dimes.MR
Reply:I have seen tig welds and mig welds that are close to indistinguishable from one another.  In some cases early on, if I hadnt been there, I would have sworn some tig welds were mig and vice versa.  I have found it's best to simply take a person on their word.  I am pretty sure they werent made with a stick...or by rubbing two twinkies together.Smithboy...if it ain't broke, you ain't tryin'.
Reply:ok my bad then, i was stating my opinion and i was wrong. Didn't know it was a battle TxRedneck
Reply:well man from montreal you know us texans...also gotta fight.  We started with the mexicans, then the indians, then the yankees, then more indians, then the spanish, then the germans, then the germans and japanese, the koreans, then the vietnamese, then the arabs, then the arabs again, and you know what else, we be fightin the okies every year UT vs OU    Hookem horns!     As far as startin a battle.  Just remember one thing, us Texans always game for a fight.  We like to fight with the okies, but you bad mouth an okie or a cajun from louisiana and you aint from texas or ok or la and well you better be makin a b-line to the door cause a good ole boy gonna bust your head.  If some yankee starts trash talkin to the southern states, us texans gonna jump on that too.  When the trade centers were attacked by foreigners, us Texans were all there to give a hand and offer a little redneck whoop azz.   When the soviets wanted to drop a bomb on our native North America, us Texans were ready with the B-52's to protect U.S. and Canada.  In World War II we were there to help defeat the Germans and the Japanese which whom may or may not have been a direct threat prior.  Either way, our english and french allies were in direct threat and we were there to battle it out.  So next time you think your gonna treat a common enemy of a Texan with hostility, especially when you take an opinion and use it like a fact, good ole Texan gonna have to deal with you.  Its not about winning or loosing, its about doing the right thing.  Besides dint your mama ever tell you aint got nothing good to say dont say nothing at all?  Well this is a danged perfect example of why.  Cause when you do sometimes your right, and sometimes you just WRONG.   Course your just too proud to apologise without making excuses.  A fine southern gentleman always knows when hes wrong he must be a man and make his apologies known and had that been done there would be no reason for all this aggressiveness now dont you think??    I hope youll think twice next time you  deciede to berate or belittle somone's work.  I also hope you think twice before insulting someone to and callin a liar whether spelled with an "L" or not.  Even if they are, aint too nice a thing to say.  And its even worse when you just inexperienced and got your head soo far up your azzhole you couldnt tell if it was welded with a heliarc or a twinkie...haha I like that one Smith!  haha  Ok,  Im done now.  Y'all have a fine day now ye hearCHRIS
Reply:Gyro:   I noticed on the second picture there is a problem along the reflection line.  The right hand side or far side of the vee has lack of fusion I believe.  Above that is a piece of glass?  If that is lack of fusion it will create all kinds of problems when you lay your next pass down unless you grind it out.  It looks like you had more heat on one side than the other since the near or left side is slightly concave and fused tot eh edge.
Reply:ok gyro what gives r ya walkin the cup free hand or whats the real deal herei gotta go for now but ill try to check ya out tomorrow
Reply:oh yeah and i love this stuff lol
Reply:gyro, correct me if im wrong, but this is automataed welding,  robotics or orbital or somethign?   If your doing this by hand your a freak god, but even if your not im still impressed with your welds eithe rway.   CHRIS
Reply:haha point(s) taken TX, perhaps i should have said in my original post "are those really TIG welds?"  Would have avoided all this i'm sure.  Yes i  don't have much experience, and from what i'd seen i thought i was right so i said it...  and i've since been educated.  I've got no problem with that, that's why we're all here no?  But please point out where i made an excuse after i said my opinion was wrong. Does he deserve and appology? sure he does, I'm sorry i doubted him.  Anyway, don't know much about Texas but i hope Rita isn't pounding you too much.
Reply:Well guys I don't have time to read all those replys. Its 3:12am and I'm just realizing I got replys here.Anyways heres the scoop.TIG! Rotator. 2" pipe. Carbon steel. Flat Position. 217amps/70wire/180rotation speed.The wire is constant feed yes.Heres some pics. I've improved since then. I'm just new to this stuff but learning for some experts.Another Tig root weld: http://img.photobucket.com/albums/v2...7/uploadme.jpgThis weld above was probably my 30th try at a tig root weld on a rotator...Ever. Theres still room for improvement on my tie in and keeping steady.Fillet weld: http://img.photobucket.com/albums/v2...7/P4010008.jpgOh and the little scorpian was welded with 18/5amps pulse. The center body is 1/8th filler rod. The tail, 035 mig stainless wire.Last edited by GYRO; 09-26-2005 at 03:18 AM.
