Применение лазерной резки для изготовления корпуса хомуса (варган) из листовой стали

Abstract

The present work opens a planned series of articles devoted to materials research of metal products of modern national culture, instruments of work, weapons and household items made in the past by local blacksmiths. These studies are conducted in order to provide technical assistance to national masters, local historians, researchers of a metallurgical culture of the Yakuts. Yakut khomuses are very popular and there is a need of serial production of quality "melodious" khomuses using modern technologies of metal processing. In this context, this paper discusses metallography aspects of the application of laser cutting to accelerate a process of manufacturing a workpiece of khomus body. Influence of laser cutting on metal structure of khomus body was investigated. A comparative analysis of changes in the microstructure and microhardness of a cut surface of metallic khomus body after laser and mechanical cutting is conducted. The thickness of a laser affected zone is defined. It is established that for cutting workpieces of khomus body it is possible to use a laser cutting, which provides high efficiency of the process in combination with high quality of cut surfaces.
