“…The analysis was mainly focused on microstructural changes and chemical stability of the joint after annealing. After annealing for 10 hours at 600 to 1000°C, a strong grain orientation was reported in the joint which further enhanced the hardness of the surface [8]. The influence of heat input during TIG welding of Inconel-718 on strength and microstructure of the joints have been analysed by Jose and Anand.…”

This work focusses on analysing mechanical properties and microscopic assessment into Inconel-718 plates in welded and unwelded conditions. Welding was performed by tungsten inert gas welding technique. Two mechanical tests such as tensile test and hardness were performed on both the types of plates to compare the properties of welded joint and unwelded plate. Although Inconel 718 possesses good weldability, the strength, ductility, and hardness of welded joint were reported lesser than these of Unwelded plate. The microstructural images revealed that metal carbides present in Inconel plate had reduced after welding. The ultimate tensile stress and elongation before breaking of welded joint were 16% and 72% lower than Unwelded plate. The fractography analysis of the ruptured part revealed that Unwelded plate possessed higher ductility than welded plate.

“…The slip bands may be formed during the plastic strain when strain-hardening occurs and may be responsible for a lower ductility. Material endure at 700 o C have equiaxial smaller grains, which can be related to recrystallization dynamics [14,15,16,17].…”

Article presents results of laser overlaying welding of metal powder Inconel 625. Laser metal deposition by laser engineered net shaping (LENS) is modern manufacturing process for low scale production series. High alloy materials such as Inconel 625 nickel based super alloy have high thermal resistant and good mechanical properties, nevertheless it's hard to machining. Plastic forming of high alloy materials such as Inconel 625 are difficult. Due to high strength characteristic performing components made from Inconel alloy are complex, selective melting of metallic powder using laser beam are alternative method for Inconel tooling. Paper present research of additive deposition of spatial structure made from Inconel 625 metallic powder with CO 2 laser and integrated powder feeder. Microstructure analysis as well as strength characteristic in normal condition and at elevated temperature was performed. Possibility of using LENS technology for manufacturing components dedicated for work in high temperature conditions are presented.
