Repair welding of gear shafts of service rollers at Železara Smederevo
Abstract
Presented in this paper are two methods for repair welding of a total of 8 gear shafts (toothed shafts) of service rollers in the "Topla valjaonica" rolling mill within Železara Smederevo. Damage that occurs in these shafts is a consequence of exploitation conditions, which lead to lateral wear of the tooth up to one half of its thickness, due to adhesion and surface fatigue. Shown in the following text are the procedures for repair welding of gear shafts, including manual arc welding (MAW procedure) and the automatic welding procedure (FCAW). In addition, the requirements that need to be fulfilled in order to successfully perform the repair welding, so that the repaired pars can be exploited again, are presented. The techno-economical analysis had confirmed the technological and economical justifiability of applying this repair welding methods, compared to purchasing of new parts.
