  • Features & ApplicationsA dramatic solution towards eliminating long hours of hard surfacing.
  • 4″ (100mm) x 6″ (150mm) X 3/16″ (5mm) thick.
  • Metallurgically formulated to give a hardness of Rockwell C60 throughout.
  • Special “Black Chrome” finish yields an exterior skin hardness of Rockwell C72.
  • Center & corner plug shape allows for easy attachment with our special Diamond Join electrode Code 1247.
  • Cost-efficient – the speed of application reduces cost and down time. Discs can be replaced individually, as needed.
  • Labor and Time efficient – much faster application than weld overlays.


The Advantages of the Diamond Disc® Wear System:

Verses Weld Overlays:

  • Diamond Disc® can be applied in about onetenth the time of manual arc welding and about one-quarter the time of semi-automatic welding.
  • Diamond Disc® has a constant hardness of Rockwell RC60 for the total 3/16″ thickness. Weld deposits will vary due to base metal dilution.
  • Diamond Discs® do not affect the base metal because excessive heat is not used during application. The high heat sometimes used in welding procedures may cause a reduction in mechanical properties of the base metal.

Verses Other Weld Plates:

  • Diamond Discs® are a manageable size, easy to store and transport
  • Diamond Discs® are one convenient size. 4″ (100mm) x 6″ (150mm) X 3/16″ (5mm) Thick. Reducing the need to stock many different sizes.
  • Diamond Discs® can be applied in about half the time of other wear plates, saving time and money
  • Diamond Discs® weigh about half that of other plates, so there is less stress on the operating systems.
  • Diamond Discs® can be replaced individually, not the complete wear plate.
  • The Diamond Discs® application pattern creates compact spaces between discs increasing abrasive wear performance.

Welding Current & Instructions


Clean weld area with a wire brush. Make sure the area to be protected is smooth and flat. The entire perimeter of the Diamond Discs® should be in contact with the base metal. Arrange Diamond Discs® in the desired pattern. Plug weld the Diamond Discs® to the base metal using a fillet weld around the circumference of the center hole using the specially alloyed 1/8″ (3.2mm) Diamond Join Electrode Code 1247. Also join where the four corners of adjacent plates meet forming a similarly shaped plug area.
