Wear-resisting surfacing welding is a common repair method in the production of enterprises. When some mechanical equipment in enterprises is damaged, this method is very useful and can effectively repair all kinds of mechanical damage. Now let's take a look at the wear-resistant surfacing repair roller press process:

1. Clean the surface of the roller, use carbon arc air gouging to remove the surfacing layer and fatigue layer of the roller surface until there is no interlayer, porosity and obvious cracks in the roller

2. Roughing and grinding the roller surface after gouging, and uniformly preheating the recovery roller to 150℃

3. Select the most suitable welding material to repair the hole in the roller surface for bottom welding to prevent the crack diffusion of the roller matrix

4. Select the most suitable surfacing layer and buffer layer of the welding material, and gradually improve the hardness, so as to improve the compressive resistance of the roller surface during material impact and mutual extrusion, and avoid the roll surface falling off

5. Finally, according to the customer's materials, working conditions and other comprehensive conditions, select welding materials to carry out hardsurface layer pattern surfacing welding

6. After the surfacing welding is completed, measure the surfacing size and roundness and slowly reduce the temperature to reduce and release the welding stress.

The technical requirements of wear-resistant surfacing welding repair are relatively high, which requires the wear-resistant surfacing welding equipment to be excellent. At present, the quality of the wear-resistant surfacing welding equipment on the market is uneven, which also causes the repair quality is not very ideal in the process of use, which makes the enterprise suffer new losses. So, remind broad user here, wear-resisting surfacing welding equipment must go to normal dealer there to undertake buying, such ability has quality to assure.
