Unter Betriebsbedingungen wird das Lichtbogenschweißen mit Fülldrahtelektroden für kritische Anwendungen erfolgreich angewendet. Durch die Erhöhung der Verschleißbeständigkeit von Arbeitsoberflächen erreicht man eine Erhöhung der Einsatzdauer von Anlagen und Geräten.
The paper gives information on flux-cored wires produced by TM.VELTEK, Ltd. and experience of their application in renovation of the parts and mechanisms in metallurgical and mining industries.
Owing to the efforts of engineering-technical personnel and workers of the shop, production was restored and manufacturing of a large range of new modern grades of flux-cored wires was mastered.
The electric arc surfacing with flux-cored wire occupies the strong positions in renovation of parts of machine and mechanisms of metallurgical equipment. For restoration surfacing of rollers of machines for continuous casting of billets the enterprise «TM. VELTEK LTD.» is manufacturing the flux-cored wire...
Extension of service life of equipment can be achieved by imparting to working surfaces of parts wear resistance in different environments, which makes it possible to reduce losses in different branches of industry. Among the existing processes, preference is given to deposition of hardfacing overlays.
