3 COMMON MISTAKES TO AVOID WHEN INSTALLING ...

Mistake # 2: Neglecting to hardface or cap the structural welds supporting the overlay plate.

Failing to hardface or cap the structural welds that hold the overlay plate is a leading reason for many CCO failures. It is crucial to recognize that welding joints are not as durable as the overlay surface itself. This implies that the weld joint lacks the same level of abrasion resistance as the CCO deposit. When abrasive material flows behind the wear plate, it can create holes in the equipment structure.

Recommended Actions for Effective Installation:

Once all the welds securing the wear plate have been completed, it is vital to apply a hardfacing alloy to cover all the joining welds. This protective measure will safeguard the joining weld deposit, ensuring that your steel plates remain firmly in place.

Exposing the edge of the CCO is a mistake. Do not allow any edge of a CCO plate to be left exposed to abrasive materials. The underlying mild steel backing plate of the CCO deposit is not hardened and will wear down quickly.

The primary function of the Chrome Carbide Overlay is wear resistance. This means that the overlay does not provide structural integrity on its own; its sole purpose is to resist wear. Once the softer mild steel base plate wears away, there is no longer support for the overlay. Much like a riverbank collapsing during a flood, the carbide surface may break away under abrasive stress, leading to complete protection failure and unexpected downtime.

To ensure a successful installation, it is imperative that: More than just the weld joints, all exposed edges of the CCO plate must be covered with a compatible hardfacing alloy. Ideally, use the same deposit as the overlay to ensure complete coverage of all edges on the CCO wear plate.
