right fix the main blade plate on large metal framework to prevent the welding deformation changes

　　Due to the manufacturing length of main blade plate is long enough and its thickness is very small, so famous brands excavator tooth pin and rubber production supplier said the main blade plate would easily has twist deformation changes during bead welding process and the correction process must be very complex, so to prevent the welding deformation changes, famous brands excavator tooth pin and rubber supplier suggests users good fixed the main blade plate on the large dimension metal framework surface first, but adopts the middle and back step welding method.

　　To solve the main blade plate deformation changes, which produced by bead welding process, famous brands excavator tooth pin and rubber production supplier said the best choice must adopts the oil hydraulic machine to finish the rolling smoothing work.

　　After the entirety bead welding steps are finished, famous brands excavator tooth pin and rubber production supplier said the harden degree for bead welding layer must equal and bigger than HRC50.
