INVESTIGATION OF HEATING INTENSITY DURING RESTORATION OF WORN-OUT AGRICULTURAL MACHINERY PARTS BY DEPOSITION OF WELD COATINGS
/ ИЗСЛЕДВАНЕ ИНТЕНЗИВНОСТТА НА НАГРЯВАНЕ НА ИЗНОСЕНИ ДЕТАЙЛИ ОТ ЗЕМЕДЕЛСКИ МАШИНИ ПРИ ВЪЗСТАНОВЯВАНЕ ЧРЕЗ НАНАСЯНЕ НА НАВАРЪЧНИ ПОКРИТИЯ
The paper presents investigation of the temperature and heating velocity during rebuilding (reconditioning) of worn-out agricultural machinery parts by automatic electric arc weld deposition. The temperature has been measured in a control section located at exact distance from the deposited coatings in order to study heating in areas of the parts which don’t need to be treated. The obtained graphical results for the specified parameters are used to select an appropriate scheme for the implementation of the process, from the point of view of reducing the thermal influence on the rebuilt machine parts.
