Building Up Plow Moldboards with Weld?

This may be a dumb question, but has anyone had any luck with building up plow moldboards with weld that are starting to wear into the softer core? I didn't know if this would be possible, or if I just let it wear until a new one is needed.

I've got an older IH 60 4-14 that has Plow Chief bottoms, so parts are getting harder to find.

I have used JB weld(liquid metal in a tube) where a spot was worn thru about the size of a silver dollar on a moldboard. Welded a small plate on the backside to hold the JB up. I've had good results, mine's lasted 2 years so far. I suppose you could spread it evenly over the whole front, like Bondo. Just make sure to get the mixture in a exact portportion like it says, or it will not harden properly.

Why not spray weld? Actually you could spray a hard weld on new ones and build it up again as they would wear and thus never wear on the steel underneath.

I think the advantage/value of this would depend on how much you plow. I mostly no-till and do very little plowing. I welded my mold boards over 10 years ago. I even added some old buzz saw blade material. I found it easier to build up the thin spots with 6013. You can use whatever low heat rod that you are comfortable with. After that I used a hard surface rod on top. The weld and the saw blade material has held up well, But I probably have not plowed over 200 acres with it. You'll have to decide if it is cost effective for you. If the mold boards are wore out you can't hurt them, give it a try. But it does take time and the hard surface rods are costly.

It has been my experence on our abrasive flinty-chert type soils that the hardsurfacing doesn't last much longer than the time it takes to weld it on. If you consider the cost of the rods(not cheap) and the time involved, I replace them when they're worn out. Even though expensive, the "company" mold boards last much longer than most of the aftermarkets,and I think are the best buy.

Use a good hardsurfacing electrode like Wearshield (Lincoln). One thing to consider is that the you need to make sure that the weld really stays on top, otherwise the harder material mixes with the soft abse metal too much.

Be forewarned, they are expensive.

Was done all the time and if was about or completly wore through a plate would be welded in first, moldboards were never replaced just repaired like that.

I agree with Larry in Pa above, that new will end up a better deal - pull easier, plow better, save fuel; and cutting, drilling, welding supplies aren't cheap these days either.

Dad would set in pieces as you say, he used old plow lays (shares) for the donner piece. Certainly can work, tho in our clay it was not as smooth a dirt flow over the patches.
