Reparation of the damaged forging hammer mallet by hard facing and weld cladding
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
In this paper the problems related to the maintenance of large forging mallets of pneumatic hammers including hard facing of cracked or worn working surfaces are considered. Actually, the choice of optimum technology for ...
Theoretical-experimental determining of cooling time (t8/5) in hard facing of steels for forging dies
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper investigates the accuracy of analytical, empirical, and numerical expressions, i. e. the most favourable methods for calculating the cooling time from 800 to 500°C (t8/5). The degree of accuracy of time t8/5 is ...
Energetic analysis of hard facing and weld cladding of an air powered drop hammer damaged ram
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper studies problems of hard facing of damaged and initially cracked mechanical engineering heavy parts of complex geometry such as large rams of air powered drop hammers. During long-term exploitation, these parts ...
Theoretical and experimental estimation of the working life of machine parts hard faced with austenite-manganese electrodes
(Institute of Metals and Technology, 2012)
We have investigated the possibility of repairing damaged machine parts by hard facing with austenite-manganese steel electrodes. The subject is a Fe-C-Mn alloy with a microstructure of soft austenite which, after cold ...
