strength of "moist" 7018 weldments?

admin

Does anyone know how strong weldments made with moist (non-low-hydrogen) 7018 rods are, compared to, say, 6011 or DRY 7018 rods?Will welds made with moist 7018 still be stronger than welds made with 6011?I did a search but can't find anything. Surely someone somewhere must have tested for this...
Reply:Other than doing a test PURELY out of curiosity, I don't think you'll find too many answers here. I can't think of anything I would weld with a "moist" 7018. I wouldn't even practice with it because it will give me false results. I don't do actual "critical" welding. However, if I weld, for example, a trailer tongue, I will pop open a new can because I consider that critical welding that I would do. For building a tailgate or putting steps on a trailer, I use the balance of the opened can."Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:as in moist you mean not kept in an oven?  I would assume it would be as strong as any 7014.  depending on the weldment, I wouldn't hesitate on using "moist" 7018.  What are you wanting to weld?
Reply:Does moist include the long standing gray smegma and mold on it from sitting out for years, I prefer dry at all costs. Define NON - low hydrogen 7018.  Better to have it dry, you might try throwing it in an oven, even the 1 in your kitchen. just leave the windows open, won't hurt anything. Ah, back up, put it in a metal pan or tin foil.

Reply:Actually, pretty strong. At my high school, we do all our bend tests with Excal 7018 straight from a can that gets stored on the shelf with all the other electrodes, no oven. And they pass just fine. I dont think twice about using my open-air 7018 here at home for everything.[Account Abandoned 8/8/16 Please Do Not Attempt Contact Or Expect A Reply].

Reply:i don't have a problem using an open can of 7018 on something on the farm that is noncritical such as a stand for something to sit on that isn't going to move or be exposed to abuse. but if it is a part on a piece of equipment or something that is going to be exposed to stress by any means or has any chance of an injury to a 2-4 legged critter or the equipment, it is done with fresh rod.225NT bobcatAEAD200LEScott 125mm175, mm252 w 30A, PT225mm211, TA 181iHyper Therm 380, cut master 529100X & XX, Digital Elite6 Victor setssmith little torch, meco midget kalamazoo band sawsteel max saw evoulution circular saw
Reply:I did some very non scientific testing on some honest 1/4-inch fillet welds, (used a fillet weld gauge) a few months ago. I clamped the fillet weld plates to my welding table, and used a 4-pound hammer to break the top plate over the top of the weld, (weak way).7018 hot right out of the oven. Beat the top plate right down on top of the bottom plate, weld did not break, had to beat the top plate back the other direction to break the weld!7018 cold, never seen the inside of a rod oven. 18 blows, weld snapped.7014 10 blows.6010 5P-Plus 10 blows.6011 8 blows.L-56 Mig wire 29 blows.ER 70S-2 Tig 13 blows.

Reply:Hey cep, those numbers seem about right with experience I have had as well as what the actual stated values from companies like lincoln and esab. Except for the tig. From what I have found the 7018 has the highest charpy values with tig right next to it. gmaw was next  then the regular rods were on bottom. Seems your tig didn't hold up and that seems curious to me.Millermatic 252Lincoln 175 plusTA 185tswTA 161stlhypertherm pmax 45Victor torchHenrob torchAn S10 for each day of the week

Reply:As much as it gets asked about "wet" 7018...I want to be related to the fella that develops a rod coating that will keep 7018 dry in a rain storm and not contaminate the weld. Or comes out with an affordable rod oven that doesn't spin the electric meter.That said, I pretty much read every thread that comes up about it.

Reply:Originally Posted by eastexanAlso, when reading this thread I was trying to remember what you posted one time on another forum, and was trying to find your post but haven't been able to. If I remember correctly, you quoted an email sent to you from Hobart answering a question you had asked similar to the OP's question.Seems like the gist of it was saying that when 7018 had been left out too long past their viable time period thereby losing its low hydrogen capability, then it would be no better (or worse) than other non low hydrogen rods. I believe that it left the impression that a damp 7018 could still make a good weld, but would lose its unique low hydrogen abilities, making it susceptable to hydrogen embrittlement. But could still be a better rod than maybe a 7014, because of its better yield strength.
Reply:CEP, maybe it was someone else's post that I was thinking of. I've been wrong many times before in my life. At least now I can say it's old age.

Reply:[QUOTE=Stick-man;549529]Hey Al, I've been looking at ovens and I want a Keen 50 pounder. It looks to be cheaper to run. If I remember correctly, it will cost me $120.00/year to run. I figured it out before, but I can't find my paper. I just want to store the balances of 3/32", 1/8" & 5/32", 7018.Stickman, I seen a few of those Keens at an auction down in Indianapolis. I remember couple of them were missing plugs and I figured they might be scrap. Now that I checked their site might have been to swap 110/220 plugs. I was going to see if I could get one but they were running 2 rings and I was bouncing around and missed out.AlA man is judged by what's between his legs...always ride a good horseMiller DialArc HFLincoln Classic 300DThermal Arc 181iPowermax 45Scotchman Ironworker(2) BridgeportsOkomota Surface GrinderAutoCAD 2010
Reply:Let me clarify my answer.things I have and would weld with "moist" 7018.  Miles of farm fence (savaged drill stem and sucker rod), outfield fence at the little league (pipe fence), angle for license plate on trailer, dog box stand, dog kennel, various farm and ranch repairs that don't see use or high stress.  I have used them on brackets and pins and nuts and keepers and almost anything else that need a glob of metal to hold.I have like most welders I know a rod pouch that we shove rods into when we weld.  In my oven, there are two sections.  In one sections are virgin rods; the other has rods that have been taken out of the oven and put back in.  I also have rods just sitting in blue containers that vary in age.  Of the three the virgin rods I use on code and life critical welds.  the reclaimed rods in the oven I use on important stuff that need not break, but life isn't threatened if it does, and the blue containers are for everything else.  just my opinion...I hate wasting money throwing rods away that only a bird feeder will see used on.
