7018 Rod Oven

admin

Well Judy's headed for the airport to fly up and rescue Mom from cold country (she stays with us over the winter) so I've commandeered the JennAir to bake up some recently aquired 7018.Non-greased rack and hold the spices.

Reply:With the potential manganese concerns out there, probably better use a dedicated oven.Next thing is temperature. Isn't maintenance of properly stored electrodes about 300 degrees; but effective dry-out and recondition requires around 800 degrees?Last edited by denrep; 12-06-2008 at 04:05 PM.
Reply:Have to set it on clean to get those temps.
Reply:800 only if it has to be X ray quality.  AND if it has been exposed since opening the package, so if it goes from the box to the oven ( I have rod heaters) It is fine.  Only needed for code work.I'll take old damp 7018 before NEW dry 6013.  DavidReal world weldin.  When I grow up I want to be a tig weldor.

I have had old 70-18 that would pin hole like mad. Then, HEAT it( 350 degrees in electric oven)  for an hour or so , then weld just great . I'm NOT saying it'd pass R-T , but sure welded  good. I have a rod oven, almost new , but quickly stopped using it . It was costing me about 50 dollars a month , for electricity, that was 15 years ago. Electricity costs way more ,now here in nor-cal.[SIZE="5"Yardbird"

My 'fer instance' would be general 3/16" and 1/4" metal fab, like Duane's work bench and the 'things'  Farmersamm makes.TIA, Craig

Reply:Originally Posted by duaneb55I guess that's a reasonable question.  I've heard of others using the kitchen oven to bake rods and never heard any negative comments and not sure there's any type of chemical release when heated as there would be while welding with it in the fumes we're exposed to.A dedicated used toaster oven is a good alternative to say the least to prevent holding up dinner though.

Reply:Man!  This thread really took off while I stepped away.Judy made it to the A/P and is "leavin' on a jet plane"  for most of the week as I type just in from the shop after burning the very first rods ever that the Syncrowave 180SD has seen as the electrode lead was still tied up and no evidence of having been used (absolutely no rod 'tracks' in the jaws).I must say I am more than pleased with how the little girl (180 SD) stick welds even though I seriously can't remember the last time I had an electrode holder in my hand.  I just haven't done any stick welding for upwards of 15 years with the exception of a little Certainium on the front casting of our oil fired boiler back in upstate NY - which I'm guessing was probably 12 years ago.Anyway, here are this afternoon's details and results:- 1/4" scrap 3" x 2" angle ground clean 1/2" minimum back from weld joint- 1/8" 7018 of unknown brand (and I ain't EVEN gonna tell you where it was or for how long it was there before I got it or there will be multiple simultainious coronaries all across the www!)- 7018 cooked in 450 degree oven for 1-1/2 hours until done indicator popped - oh wait... that was the turkey last week. - 180 SD settingsVertical down with and without slag - which needs alot of work.  Inconsistant speed and a bit unsteady.  Vertical up needs... well, we'll leave that for another day.Horizontal drag with and withoutNow to burn a couple dozen more rods to try and get the 'feel' back, work harder on vertical down and give vertical up - that I never was any good at - another try.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!

Reply:All interesting stuff.  Duane, don't bother with the vert down and 7018.  Learn how to weld up.......Like a big boy.....  Since the title of the thread is 7018, Its not made for vert down.Once you get the hang of it, its easy with all processes.  Maybe if you do some vert up with tig, then go for the stick......Nice looking machine there.Perhaps if you took some of that rod that was NOT dried and used it to show us all that it really does still work.......  I would appreciate it.DavidReal world weldin.  When I grow up I want to be a tig weldor.OK, I just went to miller website  and copied and pasted thisPosition of Weld:All Positions (Flat, Horizontal, Vertical, Overhead)It doesn't say, but.......   6013 Down, fine.  TIG down sure, MIG down, go for it on thin stuff.Don't want to sart a war."Relax, don't worry, Have a home brew"DavidEdit, I will check the bible tomorrow.   I aint home now.Last edited by David R; 12-06-2008 at 07:31 PM.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:Duane; David is right on the vert down. 7018 is for vert up only, or at least in welds where max strength is required. The powers that be say you get flux inclusions when going down hill.
Reply:Up, always up. Downhill is allowed only to repair undercut, under the D1.1~4.8.1.1(4) and 5.26 . Maximum allowable undercut is 1/32", more than that and you must make repairs.City of L.A.

Reply:Originally Posted by duaneb55OK.  Now that I've let the cat out of the bag.  Here's a prohibited V-down on top and a V-up attempt (@90A if I recall - slightly under the minimum 110A chart figure) on the bottom.  the grinder tracks are the result of a 'growth' removal when I attempted to restart the V-up to meet up wiht the V-down.And now you know... the rest of the story.

Reply:I've used 7018's that were close to 20 years + old that I found in a refrigerator in a shop that my dad took over and it was left there, about 100 lbs of them.  Lasted for quite some time, a little hard on the start, but once you got them started, they did the job nicely.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:If there isn't someone standing next to me with a WPS (not likely in my home shop), sounds like 7018 is good to use unless I found it underwater.  Originally Posted by duaneb55That's it.  So did I say - " And now you know the rest of the story" yet?
Reply:I'll take old damp 7018 before NEW dry 6013.  Ditto
Reply:7018 is -usually- listed as an 'all-position' rod.But 'all-position' doesn't quite mean ALL-position.  Some of the Lincoln 7018 rods listed as "all-position" have the detailed 'allowed' postions showing vert-up but not vert-down, or 3G-up but not 3F-up or 3G/F-down, etc.Again, per Lincoln, unopened low-hydrogen electrodes have an unlimited shelf-life.  Opened cans are supposed to be stored in a cabinet (aka rod oven) at 250-350F. Low-hydrogen electrodes exposed to air for less than one week but not directly exposed to water are supposed to be dried for one hour at 650-750F for E7018 or E7028 and one hour at 700-800F for E8018, E9018, E10018, or E11018.  If those electrodes have been directly exposed to water or high humidity, then a pre-dry bake of 1-2 hours at 180-220F is required.  Do NOT dry electrodes at higher temperatures, nor at lower temperatures for longer times.  E8018 or 'higher' are also limited to a max of 3 rebakes.  And electrodes being baked are supposed to be spread out, to allow the heat to more uniformly affect the electrodes and allow the moisture to come out from the coating.Specific electrodes -may-  have other exposure and/or rebake characteristics, so read/check the literature for the specific electrode you have.Oh, and Lincoln says don't bake Ex010/Ex011 electrodes, but some other non-low-hydrogen electrodes -can- be baked if they have excessive moisture in the coating. Check the literature for specifics.  Storage of opened non-low-hydrogen electrodes is recommended to be done in a 100-120F cabinet (notice the much lower temperature here than for storage of low-hydrogen electrodes).duaneb55,Moisture in the coating of low-hydrogen electrodes (E7018, etc) can cause internal porosity of the weld, external/surface porosity, excessive slag fluidity, a rough weld surface, difficult slag removal, and cracking.  Severe moisture pickup in low-hydrogen electrodes can cause weld cracks, underbead cracking, severe porosity, slag problems, and poor appearance.  High-strength steels (80K psi yield strength or greater), and higher amounst of moisture can make the problems worse.  At lower moisture exposure/pickup levels, the problems may only show up with X-ray or destructive testing as porosity or as underbead or weld cracking.So now you know.  The best laid schemes ...
