Abstract

Disclosed is a welding operation management device characterized by being provided with a weld joint specification table (101a) that associates material qualities of pipe materials and welding execution methods as pipe weld joint specifications in plant construction work with weld joints, a welding execution method table (101c) that associates base metal classes into which the material qualities are classified, weld material classes into which weld materials used for welding are classified, and welding method classes into which welding execution methods are classified with welding execution methods, a weld material identification table (101f) that associates the base material classes and the weld material classes with the weld materials, and a weld material identification unit (105); that acquires the welding execution method and material quality of a desired weld joint from the weld joint specification table (101a), acquires the weld material class thereof from the welding execution method table (101c), and identifies the weld material of the weld joint from the weld material identification table (101f) on the basis of the base metal class of the material quality and the weld material class.
