I was poking around on Keen Ovens website and stumbled upon this. Any truth to it? I only ask because I've seen a few guys on here recommend this method....???"The third myth on 7018 welding rod storage is that you can "bake" them in your oven at home to get the moisture out. (re-condition) That sounds logical, but again you are going to have your wife mad as heck when she sees a bunch of welding rods in her oven. (Or your husband for you lady welders out there!) To recondition wet 7018 weld rods you need to heat them to around five our six hundred degrees. Do that with your oven and you better have a fire extinguisher handy!"

Reply:Hello styles038, there are some ovens out there that have a self-cleaning function that actually gets the heat up into the range that Keen is suggesting for the rebake that you spoke of. As stated, the wife or husband or the offending rod baker will likely be shown the door if this process is noticed by one's significant other. When E7018 gets wet or contaminated by moisture it isn't just simply a matter of getting rid of the moisture in order to recondition the rod. A chemical change actually takes place and the moisture chemically combines to make up certain oxides that cause the metallurgical issues with the rod. By re-baking at the temperatures and length of time that are referred to by Keen and other sources that discuss this re-baking process, you are reversing this oxidation/contamination process. Additionally, only one re-bake is generally allowed by codes such as AWS D1.1 and others that utilize low-hydrogen electrodes. A little bit more for folks to consider. Best regards, Allanaevald
Reply:I was just curious as I baked 5lbs of 7018 this morning. 350F for 1.5hrs (as recommended by a member here). I ran across this statement on their website after I had finished. Thought it was interesting....

Reply:For any critical welding calling for 7018, let's hope the welder is following the requirements of an established code such as AWS or ASME. Here is an older post on the subject of baking out 7018 with some info from AWS. http://weldingweb.com/vbb/showthread.php...highlight=7018
Reply:I wasn't welding anything (project wise) with "those specific" rods at this time, but I seen they were left out with the case uncovered behind the radio in the garage. The last time I remember using them is over 2 maybe 3 weeks ago. I'm anally organized and haven't a clue how/why they ended up where they were? The one rod I burnt, was poris crap. After the bake, not too bad, but not like a brand new box of sticks. I would rate it as being 50% better. Maybe longer in the oven OR hotter as Keen stated would have improved the results.Baking them did not leave a preffered "home" smell. Luckily, it's only me and the dog here. He didn't seem to mind.If it happens again, I'll remember to take before and after pictures.Last edited by styles038; 03-02-2011 at 08:43 PM.
Reply:Cool, I was just curious. I'd seen some threads about it before and had people tell me to do it but I never have tried it or seen the results. Thanks for the info.Millermatic 135Syncrowave 250
Reply:I once used the kitchen oven to pre-heat some bearings.Anyway, wife came home and noticed what was for lunch. I think her first words were something like "I think you over cooked it, its all hard and crispy". Lets just say, whenever the argument comes up about who can cook better, it comes up again.You might be a redneck if you have autoparts in your kitchen stove....On a side note, it actually worked very well. Bearing slid on the pinion with no resistance at all.Con Fuse!Miller Dynasty 350Millermatic 350P-Spoolmatic 30AMiller Multimatic 200Hypertherm PowerMax 1000G3Miller Maxstar 200DX
Reply:I have the "you might be a redneck if" calendar on my office desk right now since my girlfriend thinks I'm a redneck (possibly because I have a chicken coop that's bigger than my house - nicer too, and a huge tarp on my roof to "fix" a leak since I'm too cheap to tear up the roof and find it). That quote is so much better than any on the calendar yet. Originally Posted by con_fuse9You might be a redneck if you have autoparts in your kitchen stove.... |
