Alloy 617 welding of similar and dissimilar materials: A review

This review article shows the similar and dissimilar welding of UNS N06617 (Alloy 617). It is a nickel based material that is highly chosen for hot environmental applications. This alloy is majorly composed of Cr, Co, and Mo elements which serve as solid solution strengtheners. To increase the life span and to prevent pollution to the environment, this alloy is highly preferred. Several welding techniques were taken part to fabricate this alloy using different filler metals. The presence of Molybdenum and chromium develops the cracking behavior in this particular alloy. Many researchers have reported this issue in all the similar and dissimilar weldments, that lowers the ductility of weldments. Due to the presence of secondary phases, most of the failures were detected in the fusion zone. This paper summarises all the observations in the weldments of alloy 617 carried out by different welding techniques. So this could be very useful for industrial applications such as power plants, oil and refineries, and aerospace applications.Copyright (c) 2021 Elsevier Ltd. All rights reserved.
