Abstract:
Nowadays, in various industries, repair welding of cast parts is considered toreconstruction of failed unit and equipment. The aim of this study was to welding ofG-X14CrCoMo13-10 heat-resistant steel used in SGT-600 gas turbine by TIG weldingmethod and using similar casting filler produced by investment casting method and thento investigate possible micro-cracks in the structure of the Welding and heat affected areawith using scanning electron microscopy. The hardness of the weld areas and heateffected zone was also assessed. The results showed very good bonding of the weldmetal to the ground without the presence of micro-cracks in the surrounding areas.
