摘要:
以压力容器封头常用的13MnNiMoR作为试验材料,采用埋弧焊工艺,试验研究了H10Mn2NiMoA(H10)和H09MnNiMoG(H09)这2种焊接材料对13MnNiMoR焊接性能的影响。利用无损检测和室温拉伸检测方法对焊缝质量进行检测,结果表明,采用H10焊接得到的焊缝表面存在微裂纹,采用H09焊接得到的焊缝力学性能更优,H09更适用于13MnNiMoR的焊接。根据焊接工艺试验得到的参数,通过埋弧焊工艺配合H09对某压力容器封头进行实际焊接,焊缝质量满足相关规范标准要求,工业应用效果良好。
Abstract:
Taking the common material 13MnNiMoR for pressure vessel head as the experimental material,the effects of two welding materials,H10Mn2NiMoA(H10) and H09MnNiMoG(H09),the welding performance under submerged arc welding process conditions were studied. The weld quality was tested according to nondestructive test and room temperature tensile test methods. It is found that there are micro cracks on the surface of the weld obtained with H10 welding material,the mechanical properties of the weld corresponding to H09 welding material are better and more suitable for welding experimental materials. The submerged arc welding process is adopted with the H09 material to perform the welding on the pressure vessel head. The quality of the weld meets the requirements of the relevant specifications with good industrial application effect.
