Abstract: The presentation gives an overview of the perennial problem of aging of technological and civil infrastructures. Thefocus is put on load-bearing structures encountered in advance technological fields as aviation, off-shore oil andgas exploitation and civil engineering infrastructures in the latter case bridges being most salient example. Thereis evinced the diversity of causes of structural degradation/deterioration in operation as are ineluctable manifestationof fatigue damage and corrosion effects as well as the improper operation and maintenance, unanticipatedenvironment influences, of chemical, physical, biological nature, hazardously occurring not excluding, possibly, humanerrors or man-made deliberate actions. Global statistic data are given on structural aging and degradations ofassets in order to portray the extent of the problem.

Abstract: Repairing the toothed rim of the cement mill was necessary revealing a lot of cracks at the base of the teeth, aswell as within its profile, which were endangering the safe working of the whole technological unit within thecement mill.This paper aims to present the authors’ own approach in establishing the welding technological solutions appliedto this repairing job.The repairs consisted of removing the cracked areas through arc-air gouging, welding the excavated areas withnickel-based filler, reconstructing a part of the teeth by built-up welding and machining (grinding), executedunder winter conditions, with minimum preheat temperature and without post-welding heat treatment.

❯ International mechanized, orbital and robot welding personnel – specialization in full request by the market of the welded constructions producers

Conf.Dr.Ing. Ionel Dănuț Savu, Asociația de Sudură din România (ASR),Universitatea din Craiova, e-mail: This email address is being protected from spambots. You need JavaScript enabled to view it.

Abstract: The implementation of mechanized / orbital / robot welding systems means also to ensure the specialized humanresources dedicated to the operation of those systems. The Guidelines IAB-348-13 proposes an international acceptedsolution for that desired qualification. The welding operator who is involved in the qualification systemmay access one, two or all three topics offered by the Guidelines at basics level (level B) and / or at comprehensivelevel (level C).Keywords: mechanized welding, orbital welding, robot welding, qualification of welding personnel.
