| Abstract: | Hydrogenation reactor products were made of high strength alloy steel such as 2.25Cr-1Mo-0.25V.High carbon equivalent of high strength steel was easy to produce cold welding cracks,and Cr,Mo,V and other strong carbide elements increased the tendency of reheat cracks.In order to avoid welding defects in the process of manufacturing,the welding quality of hydrogenation reactor was controlled by matching the chemical composition of base material and welding material,controlling welding process parameters,and adopting reasonable post-welding heat treatment process.The impact test and tensile test of welded specimens showed that the mechanical properties of welded joints meet the standard requirements,and no cracks were found in NDT,which could be used as technical reference for hydrogenation reactor product manufacture. |
