Optimal inert gas admission and monitoring inert gas composition and cooling temperatures of materials, useful in welding of zirconium, comprises e.g. supplying inert gas into rear side of weld seam and measuring residual oxygen content
Optimal inert gas admission and monitoring the inert gas composition and the cooling temperatures of the materials, during the welding of zirconium or zirconium alloys, comprises: e.g. supplying the inert gas into the rear side of the weld seam (3); additionally supplying the inert gas into the upper cooling region of the weld seam; measuring the residual oxygen content in the rear side of the weld seam; additionally measuring the residual oxygen content in the upper cooling region of the weld seam; removing the additional inert gas. Optimal inert gas admission and monitoring the inert gas composition and the cooling temperatures of the materials, during the welding of zirconium or zirconium alloys, which uses two oxygen measuring equipments, an isolation amplifier for temperature measurement, a data recorder, a personal computer or a laptop, a device for optical and acoustic signalization, a printer, and a towing nozzle (1), comprises supplying the inert gas into the rear side of the weld seam (3); additionally supplying the inert gas into the upper cooling region of the weld seam; measuring the residual oxygen content in the rear side of the weld seam; additionally measuring the residual oxygen content in the upper cooling region of the weld seam; removing the additional inert gas; and copper sliding contact with surface sensor on the towing nozzle including thermal plug connector, where the data for the inert gas supply including gas volumes and for the inert gas monitoring including residual oxygen content and the material temperatures are continuously assessed with the personal computer or the laptop in the sense of quality management, documented, and printed with the printer if necessary, and unacceptable operating conditions including inert gas loss, limiting value exceeding residual oxygen content and material temperatures are signalized optically and acoustically with the warning device and/or printed with the printer. An independent claim is also included for a device for optimal inert gas admission and for monitoring the inert gas composition and the cooling temperatures of the materials, during the welding of zirconium or zirconium alloys.
