My graduation work at the Bryansk Institute of Transport Machinery was devoted to the shop building for refrigerator-carriages manufacturing which I studied very closely. At the beginning of my professional career I was a master of the large welding section of a big arms factory (in the city Tula, Russia). Our production was tested by military representatives very carefully, and I had to carry out a lot of functions coupled with engineering and quality control. In order to reach the best results I myself began checking welds quality, teaching the young workers, and working on improving the quality of stick electrodes produced by the factory itself. Before I talked about some of my innovations during this period (modernizations of the TIG set, a big welding generator and a welder's mask). At the same time I participated in optimal working places organization and welding parameters searching. Also I designed an original device for accurate drilling. Working at the Kiev plant of road-building machines, besides the above mentioned magnetic device and CO2 welder I built a hinge device for curved parts drilling and a base for the welding laboratory , created some rationalization proposals. Working at the E.O. Paton Electric Welding Institute, I continued to cooperate with a lot of industries (electronic, electric, chemical, automobile, pipe-tube, ship-building, airspace, etc.), being a designer of many scientific-production projects, a consultant and adviser. In Israel I studied the jewelry processes, participated in some works related with welding, brazing and precision machinery, developed some original projects and sets for precision welding. Due to my participation in repair and regulation of the Secheron (Switzerland) company microplasma PLASMAFIX-40 units they became to work steady after 6 years interruption in their usage, and proposed by me optimal parameters while bellows welding brought the high quality of solar panels of the "Solel" (former LUZ) company. I paid much attention to the welds quality while I worked as an operator of "Cloos" big robot which produced MIG welding in argon (plus 2% of O2 or CO2). For stainless steel bodies of autoclaves there were found the optimal welding parameters which permit improving their quality and saving some manual welders. Unfortunately after my leaving the factory desposed of this robot.

Pipe station.

In 2005-2006 I took participation in the work provided by the CHEMO AHARON Metals Works & Construction Company (www.chemo-aharon.com) in the Northern Tel Aviv for the Israel Electric Company. Before the latter company used as a fuel for her Reading Power Station a coil and oil. The CHEMO Company had to build pipe station and pipe lines (more than 400 meters) for feeding the Electric Company by a natural fuel gas which goes from the Gaza region under pressure nearly 80 Bars. I participated in quality control of preparatory procedures, welding processes and welds which were manufactured by coated electrodes and argon welding. All works at the pipe gas station were made according to the welding requirements and international standards of the USA, Germany, Great Britain, Sweden, Netherlands, etc. We made many obligatory procedures including: WPS - Welding procedure specification and PQR - Procedure qualification record. The instruction "The Manual Metal Arc Process" - developed by the well known ESAB Company (www.esab.com) - was used during manufacturing and quality control of the welded station which was inspected by such methods of testing as - visual, radiographic, magnetic particles, liquid penetrate, etc. The tubes diameters of the pipe station were mainly 12 - 30 inches. There were successfully used a lot of various materials and equipment produced in different countries. Now the pipe station and pipe lines have been taken to the regular exploitation. We are getting ready to the similar customer services for the above mentioned Electric Company as well as for other companies, using modern welding technologies (like Lincoln STT, flux cored, etc.) and improved methods of welding processes and connections checking and control.
