How to Cut, Punch, and Weld Composite Wear-Resistant Steel Plates

Composite wear-resistant steel plates require specific methods for cutting, punching, and welding. The recommended techniques are listed below.

Cutting

• Plasma Cutting: The alloy surface should be cut first using air or inert gas plasma.

• Carbon Arc Cutting: Cutting should begin from the substrate side.

• Grinding Wheel Saw: Straight-line cuts can be made using silicon carbide saw blades.

Hole Cutting

• Large Holes: Plasma cutting is recommended.

• Small Holes: Electrical Discharge Machining (EDM) should be used.

• Countersunk Holes: Plasma or carbon arc cutting is suitable for assembly bolts.

Welding

• Base Material Welding: The base material of the plate can be welded easily. First, the back base material should be welded. Then, the front surfacing layer must be filled with a matching surfacing electrode.

• Structural Welding: The plates can also be welded to other steel structures.

Plug Welding

• Hole Creation: Plasma or carbon arc gouging should be used to create holes. Then, plug welding can be applied to connect the plate to other steel structures.

Bolt Fixing

• Welding Bolts: Flash or melting welding should be used to attach bolts to the base material for connection.

• Bolt Connection: Holes can also be created in the plate for bolt connections.

These methods ensure proper handling of composite wear-resistant steel plates for various industrial uses.
