既避免机械加工，又无补焊热应力热影响，修正厚度也不受***，一起产品所具有的耐磨性及金属材料不具备的退让性，确保修正部位的接触协作。

Not only to ***oid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not ***ailable, so as to ensure a hundred percent contact and cooperation of the corrected parts.
