我公司生产的某轧机鼓形齿联轴器中的渗碳淬火内齿套，在半精加工过程中扁孔尺寸没留渗碳淬火后加工余量，后用CHE857CrNi焊条对该内齿套扁头实施堆焊，再进行渗碳淬火。渗碳淬火后经MT、UT检测均满足图纸技术要求。
我公司生產的某軋機鼓形齒聯軸器中的滲碳淬火內齒套，在半精加工過程中扁孔呎吋沒留滲碳淬火後加工餘量，後用CHE857CrNi銲條對該內齒套扁頭實施堆銲，再進行滲碳淬火。滲碳淬火後經MT、UT檢測均滿足圖紙技術要求。
아공사생산적모알궤고형치련축기중적삼탄쉬화내치투，재반정가공과정중편공척촌몰류삼탄쉬화후가공여량，후용CHE857CrNi한조대해내치투편두실시퇴한，재진행삼탄쉬화。삼탄쉬화후경MT、UT검측균만족도지기술요구。
For the carburizing and quenching inner tooth sleeve in drum tooth coupling of a mill produced by our company, there isn't machining allowance after carburizing and quenching for flat hole size in semi-finishing process, so the repair welding is carried out for the flat head of inner tooth sleeve by CHE857CrNi welding rod and then the car-burizing and quenching is performed.The test results of MT and UT after carburizing and quenching can meet the tech-nical requirements in drawing.
