Scale formation-inhibitory agents used in welding treatments and method for inhibiting formation of a scale in a welding treatment of metal parts

摘要

A scale formation-inhibitory agent used in a welding treatment comprises a polymer selected from the group consisting of polymers having oxygen atoms in the main chain and polymers capable of being thermally depolymerized. The scale formation-inhibitory agent can inhibit the formation of scale on the surface of a metal part to be welded during a welding treatment.
