Welding a moldboard

[Tim May]

Looking for advice I've got a crack on a dowdeswell board what do I need to consider when welding it.?

 

[davidroberts30]

v it out and weld away

 

[Andrew K]

I think you may need a high tensile and dissimilar welding rod IIRC?

 

[bobk]

Buy another ffs , they aren't expensive

 

[Tim May]

Ycn boards are

Piece of cake

Use 7018 rods.

And its spelt Mouldboard

thanks

Have mig welded them in the past to keep us going and we have never had one brake in the same place just V it out well then flap disk it back nice the smooth on the front side.

I welded up one years back, my welding wouldn’t be the best; but as the board was still good; I thought I’d test my welding; it held for as long as we had it.

It surprising how its not needed to be humorously strong, depending a bit where it is ....
But By the way
if you have AC welder use that

 

[TechWise]

I've vee'd two out and MIG welded front and back. Both going strong years later.

Do it in stages weld it all up at once it will overheat and crack or warp.

You used to be able to buy replacement front sections for mouldboards just welded them on with regular rods no problem

Don't overthink this, just weld it.

spelt funny

This!!!!
I have Mig'd them, Tig'd them with steel/stainless filler rods and all been fine. All my match plough stuff I use stainless steel filler rod and TIG if I need to weld for whatever reason.
A very talented old school spaceframe chassis builder (French) told me all their steel chassis were welded using stainless filler wire and TIG, which I couldnt get my head around at the time but for some reason it just works, he used to build chassis for Henri Pescarolo

If you're worried about it warping bolt it to another one. V out the side you can see, weld it up, let it cool, then bolt it to the back of the good one and repeat for the other side.

The main reasons they break are wear ,ie worn thin or catching a heavy bit of ground to turn like a a hard piece of clay on the headland or because of a poorly adjusted or non exsistant stay .

If the mouldboard has worn thin the rear lower edge will be receding anyway and be affecting the ploughing negatively so replace the board and make sure your stays are all set nicely.

A new genuine ycn board won't cost anymore than another foreign plough genuine mouldboard more expensive than ucn though of course.

The usual reason for using SS filler rod is for higher carbon alloy steels to suck a little carbon out of the steel next to the weld to lessen the brittleness and cracking. Works OK for cast iron too.

V it out and we have used standards arc rods in the past. No problems.
