This would be on the stump grapple I am going to build for my tractor.Marcus
Reply:No. 7018 is not hard facing.
Reply:What electrode should I use for hardfacing 1/2in A-36 steel with a Lincoln AC225 welder?
Reply:I don't do much of this work I would look into this.Stoodite® https://www.mythermadyne.com/thc/en/...cmd=catCompareCall your LWS...Jimmy
Reply:Lincoln makes a rod called "Wearshield ABR" that is for hardfacing..We have 2 boxes here..The flux coating is black and it comes in all the standard sizes..I'll post pics when I get home.....zap!Last edited by zapster; 04-09-2008 at 02:04 PM.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 wearshield ABR's are good rods, but I pretty much use the wearshield 70's now. They are supposedly the best lincoln has to offer on metal to earth hardsurface.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:You could try searching Cabot or Stellite. I would ask your local welding supply distributor or just Google "hardfacing." You might find some useful how to guides online. I have not done it before, but I suspect some may require preheat and others would not. I know it can be done with standard coated electrodes though. The maintenance welding electrode people are very big on it and there are many suppliers and choices. 7018 is pretty soft - it can be cut with standard pneumatic grinders.
Reply:Normal hardfacing cannot be ground out with a standard grinder? I better be careful =]
Reply:Real hardfacing is H-A-R-D.A 'normal' weld deposit might be Rc20 or so in hardness. Which is still a little bit harder than 'normal' soft mild steel.A hardface weld deposit will be anywhere from Rc48 to Rc60 or so, depending on the exact hardface alloy used and how many passes, etc.

Reply:Is it any good for security devices? City of L.A. Structural; Manual & Semi-Automatic;"Surely there is a mine for silver, and a place where gold is refined. Iron is taken from the earth, and copper is smelted from ore."Job 28:1,2Lincoln, Miller, Victor & ISV BibleDanny

Reply:Make absolutely sure you are getting an ac electrode. I have used many different hardfacing rods but always on dc. They may be ac or dc for all I know but a good idea to check. Ok, concern addressed. With the exception of Wearshield 15CRMn all of the others are ac/dc.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:We've got a rod at work that does a beautiful hard surface bead, but I can't think for the life of me what it's called. It requires pre-heat and is costly...I'll check it out tomorrow. Here's a little job that utilizes hard surfaces for high wear locations. It is used for conveying raw materials for concrete.It's a 30 foot screw conveyor with a square trough and a 14" diameter screw. The sides and the bottom are from 1/4" AR400 and the outer 2 inches of the leading edge of the screw flytes is hardsurfaced. I did very little of the work on it...just a bit of final assembly. Needed to get it out the door, so they threw a bunch of guys at it. The one that it is replacing was formed in one piece and entirely worn out. We went with a bolted construction because it allows you to just change out the worn section as opposed to having to replace the whole thing. Also forming the AR 400 is beyond our press brake capabilities. 250 tons is not enough for that order...not by a long shot.We got around the forming by using mild steel angle iron flanges welded to the outside. Another interesting thing to notice it that the pitch of the screw at the infeed end is half that of the rest of the screw. I haven't worked on many screws but guess that this is common. The effect being to slow down the material where it is seeing the largest volume. In any case here are some pics...the hardsurfacing was done with an alloy wire...again not sure of the code. I remember seeing on the specs, must be the equivalent of "FABTUFF 550"Attachment 18575Infeed end
Reply:There are many kinds of hardface. Some for wear and some for impact. Some even get harder with impact. It goes on like crap. Read up on what you are going to use before buying. Tractor Supply has a hard face rod. Once its on, you can't even drill it.DavidReal world weldin. When I grow up I want to be a tig weldor. |
