The paper presents experimental results obtained in determining the chemical composition of the base material- heat affected zone пїЅ filler material in reworking by ultrasonic welding field. The work shows the curve of the concentration of carbon, nickel, chromium, molybdenum, iron, tungsten, silicon and cobalt in the resulted material couple. There are presented differences between reworking in ultrasonic field and common welding process. The analysis of the results obtained and presented in the paper shows the ...

The paper presents a new method for reconditioning of automotive parts in an ultrasonic field by reworking. Experimental results were obtained in the case of using different material couples. Using three couples of different materials, three technological metallization processes were studied: - oxy-fuel flame and wire; - three-wire electric arc - oxy-fuel flame and powder In experimental work the following material couples were studied: X30NiMoVCr11-STELLITE 12 AWS, X30NiMoCr11-TP 4000, FxMo1Si24-STELLITE 12AWS.
