excavator bucket has a higher harden requirement than main blade plate part

　　Compare with main blade plate part, famous brands excavator tooth pin and rubber production supplier said the needed harden requirement for excavator bucket part is higher, but its welding property is worse as well, so if users has adopts the No1102 welding rod to finished the common bead welding process, even through the final harden degree is match with limiting requirement needs, but because of the too large line expand coefficient different between these two types materials, famous brands excavator tooth pin and rubber production supplier said the bead welding layer would easily wipe off from bucket tooth surface.

　　So famous brands excavator tooth pin and rubber production supplier would add another extra transmission layer on bucket tooth surface, which must adopts the No4102 within four millimeters diameter as the welding rod choice.

　　For example, user needs welding the transmission layer first, then take advantage of No1102 bead welding as the cover surface layer, and the sum thickness for these two welding layers must be five to six millimeters.
