修正精度高，涂層厚度從幾微米到幾毫米，可對金屬工件呈現磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點進行堆積、封孔、補對等修正功用，只須打磨、拋光，也可進行車、銑、 刨、磨等各類機械加工，以及電鍍等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.

（1）堆焊前需先將軋輥輥身表面的疲勞層或缺陷，尤其是裂紋必須徹底清除；  

（2）在堆焊時，為了防止裂紋的產生，必須先加工軋輥輥身預熱，預熱溫度根據軋輥輥及堆焊材料而定。

(1) before welding, the fatigue layer or defect of the roller body surface must be first removed, especially the crack must be thoroughly removed.

(2) in the process of surfacing, in order to prevent cracks, the roller body must be pre heated, and the preheating temperature should be determined according to roll rolls and surfacing materials.

焊接時堆焊成敗的關鍵環節，要獲得理想的堆焊層必須綜合考慮某些可變因素，如：焊接電壓、焊接速度、軋輥轉速、軋輥的保溫、焊接電流、焊接材料等，對一些含碳及合金元素高的輥芯，為防止脆性區的裂紋，除一定的預熱措施外，多采用低碳低合金過渡層進行預先堆焊過渡層。So,ononehandcanmaketherollerstressheattreatmentshopallocationhookare。  

In order to obtain an ideal surfacing layer, some variable factors must be cidered, such as welding voltage, welding speed, roll speed, roll insulation, welding current, welding material and so on. Some roll cores with high carbon and alloy elements, in order to prevent cracks in brittle zone, have to be cidered in order to obtain ideal surfacing layer. In addition, the low carbon low alloy transition layer is used to pre weld the transition layer.
