No. It's not a waste. It's a good way of generating a thicker wear plate with good HRC hardness right through. Conventional wear plates with steel base and hard face are good till abrasion or impact works its way through the hard face. After that the plate is dealt with quickly. At least Hardox will see it gets life under the hard face.Looks good ..but isn't hardfacing hardox a bit of a waste.

But if the hardox is already around 600 brinell what's the point of hardfacing it with wire that will be around the same hardness.
That looks amazing FJ.
As im still self teaching myself how to weld and im not that far away i may have to call over to your workshop one day when your not so busy and see how it should be done
Again another great job!
Thanks and your more than welcome to pop over. My shop isn't anything extravagant but it works for me. Jut give me some notice so I can wash some cups!!!
What wire did you use to hardface it with?
I assume with all the fancy welding you have only deposited one layer?I used HW-1410 from Westbrook Welding Alloys Ltd 1.2mm
I assume with all the fancy welding you have only deposited one layer?
If so, the weld is probably softer than the Hardox (600 wasnt it?)
Hardox is quite lean (not much alloy content) and the hardness is achieved through rolling, heating and quenching thus getting the hardness but making it very weldable (for that hardness)
The weld metal doesnt have the advantage of the heat treatment so to match the hardness the alloying is a lot higher. The chances are the dilution of the weld metal by the Hardox will reduce the alloy content of the weld and soften it. I dont mean massively but it could be around 450-500 instead of the 600 Hv.
Im not trying to upset the apple cart. Just a word of advice for next time. The best weld metal to use is something like 30 Cr 5 Carbon which will be many times more wear resistant than the Hardox.
It may cost more but its flux cored so you can probably use a 2.0mm wire without having to buy a new machine........flux cored run on lower amps to reduce the dilution.
By no means have you upset the apple cart. I assume your not called Technical Al for being a class clown? This is only the third or fourth bucket i have done so each day is a school day and i am all for more/better knowledge. i have just had a rep in from IWS and we were discussing wires and welders and he actually said there is no need to buy the 30 cr 5 wire as the westbrook i am using is fine!! Your explanation somehow convinces me he is wrong?
The cutting edge is 600hv but couldnt say on the sides.
Also, my welder is a 350amp lincoln powertec. Would you think that i could run 2mm flux cored off it as it would save me circa £5-6k on a new one if so?
Thanks for the info
Dean
I did all the welding on this bucket in flat position, I just kept turning it over with the fork truck and chain. I'm excited now that I can put the money I have for a welder to something else now I know I can run the 2mm flux but (maybe a daft question) is the deposition more than using 1.2mm solid wire?
yes quite a bit more but i cant remember the numbers
the only issues are you need to stringer it.........dont weave............and it check cracks across the weld......which isnt a problem, in fact the problems arise if it doesnt crack......most wear plate also check cracks (the better ones). I also worked for a company that made wear plate and also hardfaced other items. We used to get flux cored from either Welding Alloys or from Corewire
I can put you in touch with the Welding Alloys Rep if you want..hes a mate of mine........PM me
