Scope
This document specifies the method of determining the nitrogen content in nickel-based welding materials by the melting heat conductivity method using inert gases.
This document is applicable to nickel-based welding materials (including nickel-based electrodes, welding wires, deposited metals, and welding powders) with a nitrogen content ranging from 0.005% to 0.20% by mass.
