Electron beam welding process parameters and process evaluation of RPV steel charpy restructuring sample
Abstract:To explore the electron beam welding process parameters of domestic RPV steel charpy restructuring sample, firstly,processing a series of simulation test block for electron beam welding connection, through the simulation block of weld section observation, preliminarily determine welding main process parameters; Secondly, welding procedure qualification was used on the preliminary explored welding process parameters, and the results show that:by the explored welding process parameters,various performance indicators of welding meet the requirement of RCCM,and the welding process parameters explored are accurate and reliable.?????
Keywords: welding sample restructuring process parameters procedure qualification
