welding

[fattyfat1]

the UA is what certifies you to section ix. this is your testing facility, this is your testing representative. once you pass this test, you are certified to section ix code. show me in section ix where a 6g stick weld is done downhill? please do it by pm so these people don't have to read it.none of these people here care about asme code, they want to know what welder will work best. so far you have danced around my question to you in my last post about why and are missing the point. as far as doing mt, pt, ut, and rt, good for you, you can run a magnet, an ultrasonic tester, and crank a handle on a camera. anyone with 1200$ can be a cwi, i know one who works for INTEL that did car upholstery before he inspected welds. never laid a bead in his life. at least you can weld, otherwise you have no credibility. we don't do much gas piping here. pulp and paper, refineries, nuclear, powerplants, hydroelectric, semiconductor, just about EVERYTHING but nat.gas. so don't think you are teaching me anything. you obviously specialize in a small niche of the piping industry, not taking into consideration that 99% of the piping out there is not gas pipe. 99% of pipe today is pre-fabbed and mig welded to minimize costly field welds. you are living in a dream world if you think otherwise.

One other thing fattyfat,the code you all are certified to lets you certify up or down as well,,you just need a procedure thats been qualified,,agree,most all powerplant,chemical plant type work is up,,,but to code they could weld it down if they qualified procedures and of course welders,,,in other words,if a company for some reason wanted some sch 80 a106 welded down,,according to code they could,,if they did what the code said in making that legal. U.A. ain't got nothing to do with it,its what the customer wants,,if pipefitters couldn't handle it,,they would get somebody who could.
And there ain't nothing wrong with the guy buying a mig,,probably work out well,,but I've already stated why my choice would be for a beginner to get a descent dc stick welder,,he'll just have to make up his own mind,,he's probably got way more than enough advise now.
And you don't gotta weld no 10,000 rods or what ever you said to be able to fix a crack in his brushog,,,I bet I could have him running a pretty good bead,in flat postion in an hour,and tell him all he needs to know about setting his machine up in 2 min. thingy

Get you a section IX and read it,might do you some good,,[hint] look under essental variables.
I used to be a young inspector once myself,,but no need to be so hostle when somebody is trying to teach you something,,,thingy

thingy, we have strayed WWAAYY of topic here! i will look up essential variables when i get to work in the morning, for the sake of this discussion. i admit, i am fairly new to the cwi thing, my biggest problem is code books! i never thought my b.a. would help me in the real world, but it taught me how to find what i need in a book. what i do have is good eyes, and a ton of real world experience in the piping industry. to me this is the most important atribute of a cwi. i will always be able to find the code i am looking for, just not fast w/ a customer breathing down my neck, pressuring me to prove why the weld got rejected. i am a pipefitter/welder first and foremost, my company decided i needed snt-tc-1a because the industry needs inspectors as bad as it needs welders. so whaddaya say, how about we agree to disagree. what i do know is............. i don't know squat about tractors. thats why i come here. three in three years to get it right. ha ha right! how bout we talk about them for awhile....

 

[thingy]

Alright!,,the man is actually calmed down a little,,yes,,we can agree to disagree,,but,,we was both right you know,,he'll be just as happy I bet,which ever way he chooses,,,nice to cyber meet you,,,your company is lucky to have you working for them! thingy

Tractors; okay, I have a B7100 Kubota with a loader.

The first year I used it for serious digging in rocks and clay I broke almost every factory weld on it. The fellow who fixed it used a stick and non of his welds have broken or broken beside the weld.

this,,,its alot harder to repair a weld than do it right the first time,and some welds if they fail can lead to somebody dying.But yeah,get some mexicans who can only flat weld with a mig and pay them 7 bucks an hour and you might save a few bucks in the short term,,,thinking like that works on the production line but not on pressure piping and critical welds..thingy

Who said anything about $7 an HOUR "Mexicans"??? And around HERE..companys will pay MORE $$ per hour for a top notch man that can MIG as compared to stick only!!!

Well since this is turning into a stick vs wire welding rant I guess I will throw in my humble opinion. TEACH, get as much MIG welder as you can afford. Get a gas setup right away if you can afford it. Forget about a stick welder they are just too hard to use. I have had a Dayton 230 AC/180 DC welder for about 25 years maybe 30. I have patched and fabricated many things with it and my welds never break even though they are ugly but it is just too hard to use. I don't weld often enough to stay in practice. Usually at the end of the project I will start laying down some decent welds.
So I was reworking my FEL bucket and I got fed up with my stick welder and went out and bought a Miller 251 with a 75/25% CO2 Argon gas setup. I figured that after 25 years it was time for an upgrade. I couldn't believe how easy it was to use. No more scratching, no more stuck welding rods, no more trapped pools of slag, no chipping and a 33 pound spool of wire seems to last forever. After 15 minutes of practice I was laying down the best welds of my life. I may never use my stick welder again and I have about 50 pounds of rods left. To illustrate how easy it is to learn to weld with a MIG I am going to attach 4 pictures of my daughters first welds with the Miller 251. She had never welded or done any metal work before and she only had about 20 minutes of lessons before she did these welds.

P.S. About a day after I bought my MIG I went to the local scrap yard to look for welding project fodder and I found a whole pallet of welding wire. It had been scrapped by a local welding shop for some reason but it looked usable. I bought about 330 pounds for 18 cents a pound. All of the wire is for mild steel. The wire is .035 and .045. Some is bare wire and some is dual shield wire. Unfortunately there wasn't any flux core wire that I could run without gas.
When my kids clean out my shop after I die they will wonder why I bought so much welding wire because I don't think that I will ever use it all. I have only used about 10 pounds so far.

I couldnt agree more! Every weld Ive made at school with EITHER the stick machines or the MIG setup...I take a 3 pounder to and beat **** out of it to see if its going to "hold". They all have ( thank the lord..lol) but the MIG welds LOOK 300% better..and Im a TOTAL newbie to useing MIG and have only played with my own little welder using FC.

A new guy ON A BUDGET "might" be better off WITH an AC/DC stick welder..? They certainly are far cheaper than even a decent quality MIG outfit ( even using FC wire)..but the idea than stick is the "pot of gold at the end of the rainbow" is utter BS ..IMHO. Might be more versatile??..Im not experienced enough to qualify that one way or the other..but to base its versatility on the idea that it can burn thru all the old paint...grease...rust...etc..etc..?? YA AINT SUPPOSE TO DO THAT WITH ANY WELDER. PREP is the name of the game.

After having my "paws" for 3 weeks on a 250 amp stick welder...and then switching to a large MIG welder...IF / And/ or When I feel I need a larger machine that my own little one....I'll just have a diet of hot dogs for awhile because I'll spend my "coin" on a top quality MIG welder.

for the record, section ix, b31.3 pg. 21 table qw-253 welding variables procedure spec. states uphill or downhill is acceptable. i stand corrected! darn pipeliners doing things backwards anyways. sheesh!

Sully,if you can stick weld good,you will have no trouble picking up mig,,you have already said it don't work the other way around,,and,its like in most schools who teach welding,well at least in the older days,,they started you out on oxy/act welding,,cause that process is welding in its rawest form,,if you can oxy/act weld,you can learn all the rest.Those 7 dollar an hour mexican type welders,are not welders,[there is also other races in there as well,who are not welders either],you have just described how it don't take much skill to mig weld something,,whats his name with his daughter showed it pretty good to,,,there are wire burners and there are welders.

But,,this side of argument has nothing to do with the subject,,its not a mig verses stick or verses tig,,,the guy is a beginner,,he wants to know what kinda machine he should get,,I'm assuming he knows next to nothing about welding,,,many people told him to get a mig,many told him to get a stick,,some even suggested tig,,its now up to him,,you and others have said why you think he should get a mig,me and others have said why we think he should get a stick,,,ain't much else to add here I don't think.
I can weld pipe in postion with either one,[used to be pretty good if I do say so myself],I have a stick welder,I don't have a mig,don't need a mig,if I needed one,I would have one,,,you have a mig,cause you can't stick weld,,good for you,it works for you,you don't need a stick machine,,,what else is there to say here?
