All of you asme pipefitters

I am currently doing alot of stainless high pressure pipe to flange weldments. Is there a standard time given to do these ?  I am wondering If I am charging enough . I am using a rotary manipulator and tig welding manually.  Most of these items are 6" sch 120 304ss to 3000# flanges . Given the fact that you have do to setup/fitting  , purge  , and tig weld .  I know the manipulator cuts the time down on it but anyone got a standard  say per inch of pipe?

Reply:Go by the hour...And then add the consumables... ...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:Generally speaking a Industrial Engineer conducts a time study.Applies length of time for cut ,weld prep,weld,etc. materials consumed amount of people helper,fitter,welder etc..than extrapolates obviously with a handsome profit what each weld or rate should be charged at. Aside from that as an alternative at nucor we try to charge 100$ per inch of pipe size unless they complain in which case we negotiate.By 3000# are you referring to code 61 hydraulic flg's or 1500# class weld necks?
Reply:I guess what I was getting at is the fact that i was using a positioner SHOULD cut the time down from manualy welding it. I dont want to charge less because it takes less time ...   Or  here ,   two guys do the same pipe job  . Welder #1  welds it in 1 hour by normally tig welding the pipe.  Welder #2 gets the job done in  a half hour  by using a rotary positioner.  Now, the job is worth the same price to whoever is buying it. But , Welder #2 is now worth more on an hourly basis ,2x welder #1 in fact.  Does that make sense ? Now , all I was trying to find out is if there is any guidelines on time,  for what certain sizes of pipe , processes , and material type you may come across.  Kinda like the mechanic books yes.  I guess its a matter of deposition rate when you really think about it.  I appreciate  you guys, thanks.
Reply:klondyke, The flanges were 2500lb actually  ring type - Not positive what they were running thru it -  Nice reply by the way -
Reply:I don't get in on the estimating end of things but normal rule of thumb is generally 40 inches of sch 40 (i.e. 4 10" welds) in a 8 hour day, but my question is why not tig the root then 308 1/8" stick weld then fill and cap with 5/32", with a postioner you can stay on the top and flat crank these bad boys out (unless your code or costumer won't allow this)
Reply:Nope , its for Nasa. Specified completely tig weld - believe me I'd love to just mig weld them, and you know  6" schedule 120 pipe is a big gap to fill with tig!
Reply:if you can try twisting 3 1/8" wires and crank your heat up to about 125-150 amps, but make sure you have a good solid hot pass in or it will suck the root back, are they x-raying or just visual
Reply:x-rayed
Reply:That is a good question, that brings me to another one.  As Zapster said, hourly and consumables.  I am going to start another thread about who charges for what.I am curious.DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:I'm curios too. Even though I'm still in College and learning the trade, I can't wait to get my own equipment and design and weld things.....eventually be my own boss.I assume welders who own their own shop do well.....as long as they can weld.
