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.
