Hardfacing Technical Notes - Chamfer-Plate

How To Identify
High Quality Hardfacing

High Quality Chrome Carbide Wear Liners:

  • contain stress cracks
  • have a smooth clean surface
  • have a high quality chemistry

Chamfer Plate Backing Qualities
High Quality Backing Plate:

  • absorbs impact
  • is ductile
  • is easy to weld

Fabrication Methods
  • Cutting, Piercing, or Gouging:
    • Plasma cutter (preferred)
    • water jet (for accurate cutting)
    • arc/air torch (recommended for field use)
  • Forming
    • Press brake
    • roll
  • Welding
    • See the second column

Fastening Methods

Plug Weld Mounting
Overlay will perform best when lug weld mounting is done on the back of the plate. If there is a need to provide plug weld mounting on the front or "top" of the plate, the weld can be capped with hardfacing.

Stud Weld Fasteners
A steel stud welded to mild steel back vertical to the plate backing.

Countersunk Fasteners
Heads may be surfaced with weld to provide extra protection from washout.

Edge or Backside Weld Mounting
Because you will be welding to mild steel, no special procedures aer required. In dynamic loaded structures, it is desirable to seal the mating surfaces with a weld later (or root pass) of type 312 stainless to prevent carbides from drifting into the weld zone. Weld joints exposed to abrasive wear may be capped with appropriate hardfacing material.
