Restoration of Cams of the Driving Wheel an Excavator Ekg–5a by Multi–layer Electric Arc Welding Using Ferromagnetic Charge

Abstract

The article is devoted to determining the number of deposited layers by the method of electric arc welding using a ferromagnetic charge in the case of eliminating wear on the cam of the drive wheel of the EKG–5A excavator from 35KhML steel. As well as assessing the distribution of hardness and the presence of defects along the layer height during sequential cooling of the deposited rollers and in the absence of cooling before by applying a subsequent roll in multilayer surfacing.
