Production of flux-cored wires in «TM.VELTEK» company
The close cooperation with leading research centers, including those in the field of welding and a high professionalism of engineering and technical staff and workers allowed mastering a stable classical technology of production of welding and surfacing flux-cored wires and wires for electric arc spraying to perfection. Over the period of work of the company the complex of measures on repair and modernization of basic equipment, in particular, the production lines for fluxcored wires and the charge division, was realized. The modern types of products delivery were mastered. The technologies of manufacturing flux-cored wires of diameters from 1.0 to 6.0 mm were updated.

25 Years in the World of Flux-Cored Wires
Decomposition of the USSR and emergence of independent republics in the post-Soviet space at the start of 1990s was accompanied by upsetting of industry operation, breaking up and loss of production links, mass stoppage of production. In 1993 in Kiev a joint Russian-Ukrainian Company «TM VeldTek Ltd.» was set up by the initiative of PWI staff. The Company was successfully developing in the direction of flux-cored wire manufacture. This was promoted by the support of «Dnepropetrovsk Hardware Production Association», where the management appreciated the idea of restoring flux-cored wire manufacturing in Ukraine.

Experience in application of electric arc surfacing with flux-cored wire at the enterprises of Ukraine
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.VELTEK». In the present work the developments of this enterprise and the experience of their use in repair surfacing of rolls of rolling stands, CCM rollers, wheel cranes and also the rollers of straightening machines and critical parts of hydraulic supports of mining equipment are described

Resource-saving hardfacing by arc welding with flux-cored wires
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. One of the effective ways is hardfacing by arc welding with flux-cored wires (FCAW hardfacing). Motivating factors to use flux-cored wires include the following: implementation of any alloying system, high-performance cost-effective overlay welding process, high quality of deposited metal, easy adaptation to mechanized and automated processes
