摘要:
基于涡轮中心转接管封严环薄壁零件,采用自动氩弧焊工艺对Rene41和Incol718高温合金材料进行环缝焊接,对焊接后的零件进行工艺验证,发现零件焊接变形严重,导致错边和零件轮廓度超差,冷校型后荧光检测结果不符合客户要求。分析了零件焊接变形的原因,通过优化焊接参数和改进焊接工装,解决了焊接变形。焊接后检测零件轮廓度和错边符合图纸要求,焊缝经荧光、X光检测,刨切后金相评估焊缝宏观形貌和焊缝组织,最终符合客户标准要求。
Abstract:
Based on the thin-walled parts of the sealing ring of the turbine center adapter pipe,the automatic TIG welding process was used for the circumferential welding of Rene41 and Incol718 alloys. It is found that the welding distortion is serious,which leads to the offset and the profile were over tolerance range After the process verification of the welded parts, it is found that the welding distortion of the parts is serious, which leads to the offset and the profile were over tolerance range. The fluorescence detection results after cold proofing do not meet the customer’s requirements. The causes of welding distortion are analyzed. The welding distortion is solved by optimizing welding parameters and improving welding tooling. The outline and offset of the parts after welding meet the requirements of the drawing. After fluorescence and X-ray and slicing, the metallographic evaluation of the weld macromorphology and weld structure is tested and finally meets the requirements of customer standards.
