Reintroduction in the Process of Operation of Worn Metal Assemblies, from the Composition of Public Transport Vehicles, Using Mechanized MIG/MAG (GMA) Welding Reconditioning, in Conditions of Guaranteeing Traffic Safety

Abstract

Replacing worn or damaged parts implies high material costs and financial expense for public tram transportation services, especially for the imported units and that is why it is preferable to recondition them, taking into consideration the safety requirements. In this paper, ISIM initiatives and achievements are presented in the field of cost reduction and maintenance during operation of trams, by introduction in the operation process of worn parts, within the safety limits. Aspects are presented regarding the possibilities for reconditioning and repair of parts with a circular geometry (e.g. wheel bands, axles, drum brakes). Some of these are being applied and implemented. Also, innovative ideas are presented for increasing the performance of equipment used for reconditioning.
