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 ...
