About the plant in details

   The enterprise was established in 1929, its first production were piston rings for engines of «International», «Luntsbuldo» and «Fordzon» tractors.

In further the factory sets about the production of agricultural equipment, making building mechanisms, metal constructions, repairs excavators, cranes, engines and other machinery.

   In 1959 the plant went over to making electric welding equipment by insistent proposal of Е.О.Paton Electric Welding Institute.
   The first welding apparatuses with KZESO trademark were ABC automatic welder for welding under the flux layer.

ABC automatic welder for surfacing under the layer of flux.	А 482 automatic welder for surfacing under the layer of flux.

From 1971 till 1985 putting into operation of new equipment for traditional welding is accompanied by starting of manufacturing of unique K 355 suspended welders for flash butt welding of rails. The production of a variety of welders and mobile complexes for automatic arc welding of rigid joints of pipes with the diameter from 529 mm up to 1420 mm (ГДФ 1001, «Duga», «Styk» type) and also for flash-butt welding of pipes with the diameter from 59 mm up to 325 mm (K 813, К 584, ТКУП 321 type) under stationary and field conditions was mastered.

  At the beginning of the 80ies the plant started production of ПДГ 508 semi-automatic welders and K 190ПА stationary rail welding machines. Within these years manufacturing of consumer goods was being developed and volumes of output was being increased. The plant reconstruction was being held.

  Since 1987 the production of А 1406, А 1412, А 1416, АД 231, АД 320 automatic welders and ПДГ 516, ПДГ 603, ПДФ 502 semi-automatic welders for arc welding and surfacing under the layer of flux and with tube wires starts.

  In 1990 Yaroslav Mikitin, academician of Academy of Engineering Sciences, the Chief Engineer was elected as a Director of the plant.

Considerable consolidation at the national market as well as at the international one is a result of properly chosen policy and the orientation of plant development. KZESO becomes the largest enterprise in Ukraine and CIS countries on production and working out of a wide range of highly effective welding equipment.

In 1995 continuing the close cooperation with E.О.Paton Electric Welding Institute the plant makes a powerful spurt on arrangement at production universal welding rectifiers of 300А, 400А, 500А and 1250А, welding transformers at 110А, 250А, 315А and 500А. The output of mobile four-post welding units begins on the basis of all-wheel drive automobiles and skidding tractors.

In 1996 the plant developed the output of the series of welders for resistance spot welding - КТ004, КТ007, КТ008, КТ009, and КШ001 and КШ002 welders for seam welding as well.

New computerized rail К-900А, К920 and К1000 welders, and also К-924 welder (for flash-butt welding of railway cross-pieces with appropriate rail profiles), equipped with microprocessor control systems and hydraulic apparatuses of the best European manufacturers exceed foreign analogs and took a stable place at the world market.

   Since 2007 the second area of KZESO activity begins the manufacture of track machinery  namely  the СЧ-1000 ballast cleaning mashine, the КРС-1 rail welding mashine, the СПЗ-5/UA ballast leveling mashine; overhaul and modernization of the ПРСМ-3 self-propelled welding machine.
