Fused Stainless 101..

admin

Here are the parts ready for cleaning with acetone..All 304 SCH 10...1.890 O.D.1.5 I.D.What we're after..Small tacks 3 places..Into the positioner..Fused with NO FILLER before brushing..Next.....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:Here is the same weld after the wire brush treatment..4 elbows done..Inside the tube..NO BURN THRU!!Time for the longer tube..Elbow and tube..Next.....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:You can still hold strange shapes in the positioner..Done..There you have it..Not one drop of filler was used at any time.. They are not coming apart and there is no leaks...These will be transfering water from whatever to wherever..I have more to do tomorrow that are diffrent so stay tuned.. Hey Jon K..Look good to you? I get all the fun jobs.....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:Haha Zap I knew this would be teasing me as soon as I saw the title.  Thats exatly what I have to send you -  Sch 10 1.25 Tube.   Is the trench between joints ok?  Looks nice and strong buddy!!!

Reply:you don;t NEED one, but they are nice to have i bet... how much do one of those positioners go for Zap? i'm curious to get one.Later,Andy

Reply:John..That positioner comment was not aimed at you..But it is now.. Andy..They cost around 1000$ new and you have to provide your own 3 jaw chuck..Look on e-bay..Thats where mine came from.. ...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:The welds look all concave, why bevel when your not going to add filler? I wouldn't want concave welds on my products. --Gol'

Reply:Good stuff Zap.  Would you bevel an unbeveled end to fuse weld it?

Reply:Zap,Could you go into a little detail as to why fusing Stainless without filler is so effetive by why fuzing plain carbon steel is not?
Reply:Actually No I can not..I'm not the scientist here..But I do know what works and what don'tI fuse mild steel all the time as a primary tack here and there but follow up with a filler tack right next to it..If you relied just on the fused tack for the actuall welding then they would just snap as soon as the twisting began if what you are doing is not clamped in some way.....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:Zap at most I will have some 1/2 bevels because I am cutting tubing.  Not going  around beveling it all though - I don't think it will really make a difference especially with fusing.Also my head flange is mild steel to help keep the warping to a minimum - were you going to use your prebend trickz?

Reply:First off the welds looks nice. Why wouldn't you add filler? You say it wouldn't be any stronger if you added filler to fill the joint in? I'm pretty sure it would be much stronger. I work in food processing plants and they wouldn't let a joint like that pass even on a hand rail.

Reply:Originally Posted by zapsterNothing wrong with a little "trench"..(See tack pic)They are all the same as far as the ends go..It will not be any stronger with filler.. So to keep the "mess" down I dont use any if not needed..Tomorrow's pieces are a little more complicated so I'll post more pics tomorrow.....zap!
Reply:Originally Posted by LRAmbersonI have to agree 100 percent. I understand the time savings but in a enviroment with any stress I see FAILURE The correct term is autogenous, I have never been exposed to "fusion" welding. I guess a slang term is being applied.
Reply:Originally Posted by CoalsmokeGood heaven's I don't want to start a war here, but you don't really believe that do you? I wouldn't let work like that leave my shop and if I did it would cost me a customer if I called that finished work. That is not a professional product, let alone something that should be allowed into use as any sort of process piping.I will bet money that I'll cave in the tubing in before I break the welds.. This is not for nucular science here..Water transfer piping.. No x-ray..No pressure..but it will hold whatever you throw at it..I stand behind my work..Can you?...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:Yes, it wont leak, yes it is more than strong enough for whats needed but your saying that a weld with no filler and a weld with filler are of identical strength?Have we all gone mad?

Reply:So what ya making???  A cracked pipe or crack pipe???

Reply:I gotta side with the dissenters. There is no way whatsoever I could ever sell an incomplete weld like that as a finished product. My customers would never accept that as finished. ....and some of us not only stand behind our work...we have to stand ON it and UNDER IT!!! Do incomplete welds on a 20,000# panel in the air and they will call you Flat Stanley.

Reply:i have to also side with those that think this type work is the best way to bankrupt or a lawsuit.u do have good liability insurance dont u zippy?
Reply:I work in (different) water plants every day, and every stainless weld has filler that I have ever seen. Zap, the water piping that you are making is to transfer water from one process run to another, and every one has filler. With the "trench" it could make the pipe sch 5, instead of sch 10. I hope the customer approves when they get it.

Reply:Now, everyone dont get all hot because it's "incomplete."  Some welds only require fusion, no filler needed.  That is what most of my welding involves, and it is perfectly acceptable for the job.  That is not the real question here, im sure Zap welded it to the customers specs.The question is the one that I stated above.Have we all gone mad?
Reply:[QUOTE=grahamtheengineer]do you guys not get that this will be an un-loaded member ? ?  ?  and carry an unpressurized fluid...QUOTE]Depending on what plant and where in the plant it going to, these run as low as 20 psi to 140+ psi. With the bends in the pipe it creates turbulence in the water and wear over the years or months depending on the water quality. Add to that water hammer from automated equipment and it could be a bad day.
Reply:If it is unloaded, then fine, but this thread was created in response to the guy trying to build a TURBO HEADER, which IS a loaded member. If that were a turbo header it would not last 100 miles.
Reply:Originally Posted by grahamtheengineerSome of you are way to critical when it comes to the strength of welds....do you guys not get that this will be an un-loaded member ? ?  ?  and carry an unpressurized fluid...have you ever heard of optimizing production and cost ?For what these pieces will do ....they are fine.  I believe my honorary degree in mechanical engineering and master's degree in materials science and engineering has allowed me to come to that conclusion.
Reply:Originally Posted by welderman1I will agree with this.
Reply:Originally Posted by LRAmbersonUnderstood, my issue,I have a very misguided conception that the reduced size if the joined tubing being thinner would be as strong as the original thickness as not to mention the heat affected zone. I am just looking for clarifacation, without a ego driven snappy response.
Reply:Ain't a one of ya that knows what the specs were on that job.  I can't imagine the job being done that way if it wasn't acceptable to the customer.  Awful  nice looking work there, Zapster, I tend to think that if the customer wasn't going to accept it you wouldn't have done it that way.
Reply:lawsuit???Nah.....   100 miles   ...ok  I dont know  why would one thinks so  just wonderin  ..  just wanting to learn something  here. weld it like you own it

Reply:does it really matter if its stronger with or without filler if it does what its supposed to do? no it doesnt. if it fullfills its purpose then itll work. i stand by zap because i think hes been in the game long enough and done enough of this sort of thing to know what hes doinghttp://datingsidorsingel.com/
Reply:Originally Posted by lewray     .25 wall ss w/o filler I would have no problem for my ROCK-CRAWLERS in mounting winches or just about anything else.     I could not break any test coupons with a sledge hammer doing it this way............

Reply:Ok, take a break.  Supprising how many posts came up so fast on this subject!If joint is not filled to the top is that ok?What if there is suck-back (concavity) on the inside of the joint, is that ok?What if there is excessive drop-through on the I.D. (convexity), is that ok?What if the weld meets all the requirements for strength, but it doesn't look pretty to me?What if you radiograph and find some porosity?What if, what if?What spec are you working to."   The bottom line is, the customer needs to specify the acceptance requirements for the weld.    Whether it involves AWS, ASME, API, or whatever specificaiton, you can choose to provide a "better" or "prettier" weld than the customer requires, but, that is "not required".Maybe the tube thickness is for this particular job is oversized for the stress loading, and so it is acceptable for the weld to be "underfilled".Last edited by pulser; 11-29-2007 at 11:11 PM.
