Wear plates or preventive-hardfacing applications preferred to prevent the wear. For parts with large volumetrics or complex designs, it is necessary to manufacture these parts in pieces and connect these parts with joining welding.
Metal cored wires have better efficiency and higher welding speed compared to rutile cored wires and solid wires (SG2, SG3 etc.).
Wear plates can not be cut with oxy-acetylene or oxy-propane methods due to high carbide content. These plates must be cut with plasma or laser cutting method. CNC controlled machines are used for cutting as seen from the image below for multiple or complex pieces.
Wear plates are abrasion-resistant composite steel plates manufactured by hardfacing on different base materials. Depending on the required hardfacing alloy type, these plates can have chromium - niobium - tungsten - vanadium - complex carbide microstructures.
