hardfacing

I'm going to use Lincoln's Lincore 60-O wire, I will take pictures and let you guys know how it goes if I get to do it.

I've done lots of hardfacing with that exact same wire.Horizontal position and probably five or more 25# spools.Some were partially used.I used full leather gear.Lots of drips and splatter found any exposed holes.Most of them were the tounge of my shoes.Pretty much like running regular flux core but very sensitive to wire feed issues.Not too much roller pressure,new liner,keep cable straight and new contact tip.

Do you think it is worth the effort to remove the trencher shoes from the machine and do them flat? In my opinion it is worth the 2+ hours to R&R the shoes to not have to deal with the extra spatter of doing it up in the air horizontal.

I don't know,your call.Try on scrap first to see how it runs horizontal.Less time involved =more money.

Most definately run some practice coupons.
Seeing how Hard-facing is a buildup electrode, the puddle runs above the materials surface with minimal penetration. It actually feels-like there is no penetration.
Surface preparation is important.
A moderate preheat of thick material helps.
I found it fun to learn and do.

If the job does not land, maybe give Hard-facing Stick electrodes a try. Ground engaging equipment loves this stuff.

Can you take a picture of the job before you start? That would help to give a little input if youve overlooked something.

I will try and swing by tomorrow and take some pics.

I purchased hardface wire from these people. They have it available in .035 and 10# rolls. It has worked well for me on the limited applications I've done on my equipment.

I have the HTP2400 welder and it works well with that machine.

Love to hear how it goes.

Years ago I was doing some subcontract work at a valve company. They had automatic wire fed welders hardfacing valve seats on 30" high pressure valves. The welder stood still and the body would spin. They used one of the overhead cranes to lift the spool of wire up to the machine. Of course they had lots of impressive toys.

I did that job today, that 60-O wire was awesome. I went ahead did it horizontally on the machine, I was surprised by how little it popped or spattered. It was 6 hours of welding like I expected it to be. I wish my camera was working so I could have taken pictures.
