Material manufacturing requirements and workpiece connection of composite wear plates
Dec 26, 2018

The composite wear plates is mainly made of powder metallurgy composite technology and hard surfacing process. It is made of high-boron alloy cast iron material on ordinary low-carbon steel or low-alloy steel plate with good plasticity through special equipment of carbon arc arc and surfacing welding. It can be made into different thickness wear-resisting layers according to customers' requirements and different working conditions. The wear-resistant layer is scattered by arc welding stress, and fine cracks are generated on the surface. This crack will not spread to the substrate and will not affect the wear resistance.
The welded DS substrate of the composite wear plates is a steel plate with good weldability. When docking, it is necessary to first weld the back surface together, and then weld the front wear layer with the corresponding electrode. Can go to other steel structures. Bolting The bolts can be welded to the substrate by flash or fusion welding and then joined to the workpiece. Holes can also be made in the holes and connected to the workpiece by bolts.
The plug welding of the composite wear plate is opened on the DS, and the work is connected by the plug welding method, and the wear layer of the front wear layer is welded by the corresponding DS brand electrode. The cutting of the whole product is mainly carried out by DS surface welding of high boron alloy cast iron, so it cannot be flame cut, and can only be cut by plasma cutting machine, laser cutting and electric discharge machining. According to experience, in order to prevent the wear layer from falling off from the substrate during cutting, it is recommended to cut from the substrate surface.
