Good use of the idea, and nice hard facing runs. Job looks tidy.
What hard face and buffer layer products do you use? Or just straight on with the hard material?
I used to do a regular job with an ex firm where we would build up the knife blades on a shredder.Not one comment ?
It also depends on what hardfacing it is. It's not a field I'm an expert in but some hardfacing is designed to cross check (crack across the width of the bead) this is a form of stress relieve allowing cladding of materials that is simply not weldable with massive carbon content. This hard face would need completely removing before a reclad as you can imagine those cracks get filled up with alsorts in service.Doesn't the hardface on hardface break off in chunks when the machine is in use.
No problem with cracking? Some hard face applications require an intermediate layer of a material not as hard as the hard face, but harder than the base metal.
It can make the hard facing last longer, as there is less dilution with it and the base metal. You might double the time between jobs. Of course that may not seem desirable but you can charge a bit more and be the guy who extended their plant life. Feather in your cap maybe.
Think of a sheet of glass sat on a sheet of hard rubber
What will happen if you press hard on the glass
now add a thin sheet of mild steel between the glass and the rubber
what will happen now when you press hard
How fast does it rotate? could well need re-balancing after that much welding.
