Recovery the surface abrasion damage to recycle use the old teeth pin

　　Generally speaking, we can choose the high casting method to welding the professional welding strips on the abrasion position of the old excavator tooth pin and rubber, after several minutes later, the appearance of the old excavator tooth pin and rubber would change into its original condition, and just looks like the new teeth pin. The next step is to cleaning the surface of the old excavator tooth pin and rubber, to ensure all of the water, oil dirt and surface cracks can be clean out, then choose the surface hardness method to recovery to surface flaws.

　　Next step is that use the high chrome alloy steel surface welding strip or other kinds hardness surface welding strip to welding a uniform layer of the resistance abrasion alloy steel coating on the surface of the old excavator tooth pin and rubber, and people need according to the different use conditions to choose the different welding methods of the resistance abrasion surface welding process.
