Choose the single channel continue resistance abrasion surface welding method to welding the teeth tip position

　　To the teeth tip position of the wheel loader tooth pin, people can choose use the single channel continue resistance abrasion surface welding method to reduce the abrasion damage happen rate, but to the end position of the teeth, writer suggests to choose the cross narrow welding method. Because we need to use the wheel loader tooth pin to exploit some big size of the materials, so to ensure the longer use life of the wheel loader tooth pin, people also can along to the length direction of the teeth pin to provide the surface welding process, so use this way, we can leave out the suitable gap for each teeth pin end.

　　But if the appearance of the materials are the grain shape, people should choose the parallel welding method on the surface of the wheel loader tooth pin, the purpose is to reduce the teeth pin has the surface abrasion damage.
