Sažetak
Nickel alloys are used because of their corrosion resistance, heat resistance and high and low temperature properties. In this article types of nickel-chromium-molybdenum alloys are described and guidance is given on welding processes and techniques which can be used in fabricating nickel alloy components without impairing their corrosion or microstructure properties. Tungsten Inert Gas of 7 mm thick nickel based alloy HASTELLOY C-22 has been conducted in butt joint configuration. The need for complex and detailed preparation of plates prior the welding, and welding discipline has been presented. Microstructure of the weld metal and heat affected zone was examined using scanning electron microscope. Composition of the weld metal and heat affected zone was examined using X-ray fluorescence analyser. Comparative electrochemical corrosion tests were conducted to determine the influence of welding on corrosion resistance properties.
