What rod would you use for this project?

admin

I have a lincoln electric 225 ac welder and need to choose a welding rod for a stump bucket.  Should I use 6011, 6013 or 7018?I have attached a picture of what I want to build.  It will be made from 1/2" A-36 plate. Attached Images
Reply:I would use a 7018 AC rod. Asked your LWS for the AC only rod.Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.
Reply:Since I don't have a rod oven, can I purchase 7018 rod and leave it in the sealed box, then when i have all the parts ready weld it within 4 hours?After that amount of time, does the 7018 rod become useless?Thanks,Marcus
Reply:your 7018's will be fine as long as you don't leave em in the rainDewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools
Reply:I use the plastic rod storage containers and have had rods in them for months and was able to use them. I rod over is a nice thing to have but not necessary for most welding projects. I would leave the box sealed though until you were planning on using them.Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.
Reply:If you're gonna multiple pass anything, you might use 6011 as a root and 7018AC to fill it out.The 6011 will be easier to fill any gaps you have and the better penetration characteristics will help. The 7018AC cap will then strengthen it nicely.My toys includeMiller Bluestar 2E AC/DCMiller Thunderbolt 225O/A outfitMany saws, grinders, drills, etc.
Reply:I personally would run a 7018 all the way out.  It would be a stronger weld than rooting with a 6011.  However, if you are just using 1/2" mild steel most any of the general purpose rods will work fine.  Considering you can turn the bucket anyway you want to weld it in a flat position then I would look into a 7024 electrode.  It lays down quick, and smooth as butter, and the flux will just fall off.  I wouldn't worry about running a 6011 root, and capping etc...  since you can bevel and weld all seams from both sides you will be fine.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......

Reply:A stump bucket or stump grapple is just a narrow loader bucket, usually with aggressive teeth.  They are used to dig and pop stump out of the ground or may be used for trenching up to about 2.5 feet deep.  If you have a grapple on it, you can pop the stump, then carry it to the burnpile.here is another pic Attached Images
Reply:ACE7018 is not reconized by AWS. like hammik said 6010 6011 6013 are all fine. Shoot if you can make all of the welds in the flat and horizantal positon i would use E7024. Turn it up and cruiz --Gol'
Reply:7024 is great for this as is 7018 though I would get Excalibur 7018 as you will like it a lot better than 7018ac. My experience with this type of stuff (I.E. grapple buckets and such) is that 6010/6011 do not hold up as well as the 7018 and 7024. 6010 is strictly dcep and will not run on your machine. I use 6010/6011 for the fist pass if necessary and always finish with one fo the other two I have mentioned. This stuff gets seriously abused, but I never get them back due to weld failure and since they are warranted I am sure I would if it happened.The difference between art and craft is the quality of the workmanship.

Reply:also another place to store stick electrodes is to put them in by the hot water cylinder in your house. i leave them in the sealed container as well and it seems to work just fine for mehttp://datingsidorsingel.com/
Reply:What ever rod you can run the best.  On AC your choices are limited a little.  I would use 7018AC or 7024 which IS an AC rod.  It only runs flat but will be beautiful.  6013 will work fine if you are comfortable with it.I would love to see pics as its being built.Real world weldin.  When I grow up I want to be a tig weldor.
Reply:I wouldn't even consider anything but 7018 or 7024 but that is just me. If I use either one I know it won't break. You might bend it into a pretzel but it will still be in one piece if done right.
Reply:I stumbled across this link discussing steel/welding/metallurgy of construction equipment.http://www.forester.net/gx_0011_metallurgy.htmlFor the rod, since you are building the bucket from A36, with a minimum yield strength (YS) of 36 ksi (limit at which the steel will permanently deform), and an ultimate tensile strength (UTS) of 58 to 80 ksi (limit at which the steel will fail), a 70 ksi UTS filler rod is a good match.  Like others said, I would try to position the welds flat and use 7014 and 7024.A36 steel in this application probably does not really require the low hydrogen 7018 rod because it is a relatively low strength steel, it is low carbon content (<0.25 %), and it is not a critical application requiring special low temperature notch toughness or impact toughness properties.  7018 is specically designed to prevent hydrogen embrittlement in higher strength steels and critical applications.New or properly stored 7018 would of course work great for your application.  But, I caution against buying a 50 lb tin of 7018 for this job, because you know won't properly store it in an oven at 300 +/- 50 F after you open it, I'd bet most of the guys recommending 7018 don't store/handle it properly.  It simply is not be good practice, and could lead to severe cracking if you use 7018 that has not been properly stored.
