In 1993 in Kiev on the initiative of the group of colleagues
of the E.O. Paton Electric Welding Institute
the joint Russian-Ukrainian enterprise OJSC «SP
TM.WELTEC Ltd.» was founded. The successful start of
production of flux-cored wires in the new political
and economic conditions of the 90s was provided due
to the support of the «Dnepropetrovsk Hardware Production
Association», whose management treated the
idea of restoring the production of flux-cored wires
with understanding. In 2001, the production of fluxcored
wires was allotted into a separate division: the
company OJSC «TM.WELTEC Ltd.».
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.
The efforts of the enterprise allowed preserving a
significant part of the market of welding consumables
of Ukraine for domestic producers and providing the
consumers with quality materials at reasonable prices.
The practice of work of the enterprise includes rendering
consulting advice on the choice of material,
the optimal technology and equipment for its realization,
providing engineering support of the production
process. In some cases, the enterprise produces fluxcored
wires according to technical specifications, individually
agreed with the customer. The weldability
of the already mastered grades is constantly improved
and new grades of wires are developed, which have
no analogues.
Regardless of the nomenclature and volumes of
batches, the high scientific and technical potential
of the enterprise allows fulfilling the orders in the
shortest terms and with the required quality. This allowed
occupying a large enough share of the market
in Ukraine, ensuring stable fulfillment of foreign contracts
and becoming a permanent partner for many
enterprises.
As to their purpose and technical characteristics
the flux-cored wires of grade WELTEC are not inferior
to the products of leading foreign companies, which is
confirmed by their high estimate at the domestic and
foreign exhibitions, recognition by the leading enterprises
of Ukraine and CIS, the continuous expansion
of application areas and growth of sales volumes despite
the ever-changing economic and political conditions.
Over the years of work the enterprise acquired
the status of a reliable partner at the market of welding
consumables in Ukraine, Russia, Belarus, Uzbekistan
and other CIS countries, Lithuania, Latvia and also
the Czech Republic, India.
Since 2004, at the enterprise the quality management
system was realized certified by UkrSEPRO and
the Russian Maritime Register of Shipping, which
meets the requirements of DSTU ISO 9001:2009
(ISO 9001:2008, IDT). The certificates of conformity
UkrSEPRO on more than 100 grades of welding and
surfacing flux-cored wires, the Certificate of approval
of welding consumables of the Russian Maritime
Register of Shipping, the Certificate of approval of
welding consumables Lloyds Register and the Certificate
on approval of welding consumables of the Register
of Shipping of Ukraine were obtained.
The flux-cored wires of grade WELTEC are used
in a wide range of industries: at the railway enterprises,
at the integrated works of mining and metallurgical
complex, at the plants of metal structures, at the
machine-building plants of mine, transport, hoisting
equipment, in shipbuilding, diesel locomotives and
carriage engineering. Below the nomenclature of a
