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 surfacing using flux-cored wire finds a wide application in many branches of industry and, first of all, in the repair works. At the present time the largest manufacturer of flux-cored wires for surfacing in Ukraine is the enterprise TM.WELTEC.
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...
