This unit is designed and delivered by "Engineering Center of Beam Technologies" of E. O. Paton Electric Welding Institute supported by the specialists of OJSC "Turboatom".
According to the Chief Engineer of the plant Gregoriy Ishchenko, in accordance with the current investment program of technical re-equipment, the company is continuing implementation of the new equipment and new technologies. "Commissioning of the new welding equipment allows us to return to "Turboatom" from cooperation of work on welding blade stacks amounting to more than 1 mln. UAH annually. In addition, we have created new working places in the steam turbine workshop". He also noted that the unit of electron beam welding would allow improving the quality of welded joints, reducing the production cycles and increasing the culture of performing the welding work.
The representatives of E. O. Paton Electric Welding Institute trained personnel of "Turboatom" in terms of the new equipment operation. The corresponding certificates are issued to employees of the workshop No. 53, specialists of the department of the chief welder and repair services.
As Aleksandr Kantor reported, the Head of Bureau of the Department of the Main Welder, the dimensions of the unit were 2,5 x 3 m, the unit included vacuum chamber with electron beam gun, vacuum station, as well as high-voltage power source. The work on the unit is performed automatically using NC system. "The advantage of electron beam welding is to give opportunity of welding of finish-manufactured parts made of high and difficult-to-weld alloys. Welding is carried out in a high vacuum mode, it provides reliable protection of the weld puddle and zero-defect of weld joints. We have already received the first order, it will be the steam turbine blades for Uglegorskaya TPP (Ukraine)", he noted.
