| Summary: | Modern industry and transport industry are impossible without the use of technological methods and means of restoring the operational characteristics of equipment. Railway transport enterprises have recently paid considerable attention to the development and implementation of resource-saving and environmentally friendly technologies for the repair and restoration of rolling stock components. One of the new directions in this area is the combination of high-quality surface preparation using innovative resource-saving technologies, such as surfacing [1].
The use of surfacing to restore railway wheelsets has significant economic advantages. This technology allows you to minimize the loss of rim metal during its mechanical processing along the rolling profile, and also increases the wear resistance of the wheel due to the use of materials with pre-set characteristics. To perform such restoration works, methods of arc surfacing under a layer of flux using solid-section wires, as well as specialized welding and auxiliary equipment are used [2].
The article analyzes the relevance and expediency of restoring railway wheelsets by electric arc surfacing. An overview of recent research and publications on this issue is provided. Organizational, technological and technical aspects of the restoration process, including mechanical processing after surfacing, are considered in detail. Tools, equipment, methods and means of safe performance of restoration work at the KT 003.00.00.000 installation based on the experience of the Pokrovskyi car depot of the Donetsk Railway are also analyzed [3].
As a result, conclusions are drawn about the prospects for further research aimed at improving the efficiency of processes for restoring the profile of railway wheelsets using electric arc surfacing. |
