“…At the same values of I m , R1, τ charge and f p = = 100 Hz, P R1 max = 13.44 W, and P R1 max = = 6.92 W at f i = 50 Hz. It follows from this that recommended area of frequencies f p is limited by values from 80 to 120 Hz, and in the case of AESA application only for initial excitation of direct current arc the nominal power of resistor R1 can be significantly reduced in comparison with calculation one and make 4-6 W. Power resistors of C5-C35 or SPS, SQZ, SQHG series [28] are reasonable to be used as R1 resistor.…”

“…This technology also is of great interest for solving aerospace and military tasks when working with titanium alloys [27]. PWI performed a number of studies on welding titanium alloys, aluminium alloys and stainless steels to meet the objectives of Ukrainian aerospace industry [28]. In this work the applicability of both laser and hybrid welding was studied.…”

Plasma-Master Ltd.» is the recognized leader in Ukraine in the field of plasma-powder surfacing (PPS). How was the company founded? What problems were encountered at the initial stages of its foundation? As you remember, in the early 1990s the situation in the country was complicated and ambiguous. The disintegration of the Soviet Union, rupture of economic relations and galloping inflation made many people think over: what is next to do? How shall we do? Our activity at the PWI, where I was working by then, had vague prospects. Later, me with a group of young specialists working along with me in the PWI, decided to organize our own company, which was supposed to be more survivable and effective in a rough sea of market relations. The company under the name «Plasma-Master Ltd.» was registered in April, 1992. In the name of the company the word «plasma» implies a source of heating and we were going to work with using the PPS process. At the beginning it was difficult because of the lack of finances, facilities and equipment. But the knowledge and experience gained in the PWI, as well as foreign relations and sponsor assistance, allowed us to get used to the current situation very quickly. And in 1993, we had already delivered the installation for PPS of our own design and separately two new plasmatrons of different design to Germany. This success gave us confidence in our work. Later we encountered another difficulties, life brought also its corrections. Gradually, all the co-founders left the original team, but me, as the director, and the «brand» remained faithful to our business. The company mainly gained its development since 2000, when Ukrainian economy began its gradual revival. At the present time, in spite of objective difficulties, the company remains stable and has broad foreign relations. What are the main activities of the company? The R&P company «Plasma-Master Ltd.» was founded in 1992 by the specialists in the field of technology of welding and surfacing. It has a research and production activity and is specialized on fulfillment of complicated engineering works. The company has several production facilities equipped with advanced welding, surfacing and machining equipment, which in combination with a gained experience of the company specialists allows solving the complicated technical problems. The company staff amounts 40 associates, mainly of research and engineering profile. The company is cooperating with research institutes of Ukraine, first of all with the E.O. Paton Electric Welding Institute of the NAS of Ukraine.
