Characterization of Tube Repair Weld in Thermal Power Plant Made of a 12% Cr Tempered Martensite Ferritic Steel
(Springer-Verlag Berlin, Berlin, 2017)
The heat resistant tempered martensite ferritic steel X20CrMoV121 (DIN) has been extensively used within the last few decades as a material for boiler tubing systems and pipelines in thermal power plants (TPP). Long-term ...
Charpy and SEM investigation of Al-Mg friction stir weldments
(International Conference on Fracture, 2017)
Influence of friction stir welding processing variables on Charpy impact fracture behaviour of Al-Mg 5083 alloy was studied. Rotational and traversal welding rates were linked to the dynamic crack initiation and ductile ...
Influence of crack position and repair activities on the stress state in a shaft tooth
(International conference on structural integrity and durability 2017, ICSID 2017, Book of abstracts, 2017)
Numerical analysis of the stress state in a tooth of a repaired shaft in Zelezara Smederevo is presented, along with the repair welding procedure. The need for repairs arose due to exploitation conditions and regular ...
Repair Welding Of Lower Rails Of A 30CrMoV9 Steel Transport Beam And The Conditions Under Which The Welding Procedure Must Be Carried Out
(Proceedings of the 5th International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2017), 2017)
Welding technology used for repairing of the lower rail of a 30CrMoV9 steel transport beam is
