Product: Bimetallic wear protection
Machine: All types
Application: Mining / Construction
Activity: Protection of high wear areas
Some areas on the buckets are particularly susceptible to wear; this determines them
as critical points. One of the best ways to protect these areas is through bimetallic
wear protection; they serve well on high abrasion and impact conditions. Top white
iron provides 700 BH harness for top abrasion resistance while bonded mild steel
allows a cushion for impact and welding ease.
Due to versatility, the most popular presentations are chocky bars and wear buttons.
Chocky bars can be bended to shape due
to notches on the mild steel and white
iron geometry. To do that tack weld one
end and hammer down unwelded area.
Even though chocky bars are an
excellent protection, them being
straight with square angles could rise
stress in undesired areas.
Wear
buttons avoid this stress by making
welding to circle.
Note: Very important
to
follow
welding
procedure and to keep
welding 2mm below
bonding line to reduce
delamination risk
