摘要:
利用X射線衍射法對圓筒對接焊縫的殘余應力進行測試分析。研究焊接殘余應力測試方法,給出合理的電化學腐蝕參數,即合理的腐蝕深度。分析電動打磨與手工打磨對殘余應力測試結果產生的影響。分析殘余應力測試對電解拋光的具體要求。分析不同腐蝕深度下殘余應力的變化規律。結果表明:1) 電動打麿破壞試件表面殘余應力分布,手工砂紙打磨使試件表面殘余應力增大;2)電化學腐蝕后的拋光處理對表面殘余應力測試值有一定影響,拋光不完整導致殘余應力值減小50以上;3) 試件表面殘余應力隨腐蝕深度增加有減小的趨勢,與理論分析結果接近。
Abstract:
Using the method of X-ray diffraction (XRD) was carried out on the cylinder of the butt weld residual stress testing analysis. Research for a reasonable parameters of electrochemical corrosion, including corrosion of voltage, current time on welding residual stress test. Analysis of electric polishing manual polishing on the effect of the residual stress test results. Analysis of residual stress test of the specimen surface roughness requirements. Analyses the variation regularity of residual stress under different corrosion depth. The results showed that: 1) Electric polishing damage specimen surface residual stress distribution, h sing make specimen surface residual stress increases; 2) Electrochemical corrosion after polishing treatment on surface residual stress test values have a certain influence, polishing incomplete cause the residual stress value decreases by more than 50; 3) The surface of the specimen with the increase of corrosion depth has a tendency to reduce residual stress, confirm to the theoretical analysis results.
