摘要
Abstract
In order to study the welding characteristics of ultra-thick wall 20 MnMoNb mate-rial,process experiments were conducted using specialized matching welding materials and welding processes.Based on the characteristics of 20 MnMoNb material and welding process,the welding material,welding groove,welding specification parameters,intermediate heat treatment,and final heat treatment specifications were analyzed and determined.Nondestruc-tive testing and mechanical performance analysis were conducted on the weld seam,and the welding joint performance met the requirements of NB/T 47014-2023.关键词
