Objective: Specialist in materials engineering, precision welding and machinery
Summary: 30 years of experience in welding of thin metals and precision structures, sensors, bellows, fuel elements, membranes for extra pure hydrogen producing, pipes, heating and melting vessels, made from platinum metals, stainless autoclaves.
Experience: 1 year – toolmaker, 1.5 – foreman, 10 – senior technological engineer, 5 – group leader, 7 – manager of division of Construction-Technology Bureau of E O Paton Welding Institute, 6 – senior staff scientist, 27 – lecturer, 3 – manual welder (microplasma, argon, CO2), 1 – operator of a big welding robot, 2 – jeweler , 7 – designer and repairer of welding, electrical and precision equipment, expert.
2002-2005 - Worked out the projects “Multipurpose Microplasma Set” and ”Microplasma Set for Dental and Medical- Biological Purposes”- mainly for incubators. Prepared the main materials for a book about precision welding technologies. Made the report about the new microplasma set at the International Conference “Noble Metals – 2005” ( Berlin , Germany ).Inspected the welded pipe station.
1999–2002 - Designed and built a prototype of Multipurpose Microplasma Set (MMS),which shows very good results for stainless steel welding, jewelry and dental purposes. Designed, built and modernized some devices for jewelry. Made the model of manual device for microplasma spraying. Built some original plasma blocks. Calculated compulsory assembling conditions for different thin-walled seams stable formation - without filler materials usage (for metals up to 1 mm thick).Showed that they are rather large.
1998–1999 - Operator of a big welding robot (from “Cloos” company, Germany ).Found optimized welding parameters
1996-1998 - Studied jewelry processes; designed and built original blocks, which in addition to standard welding equipment give possibilities to make plasma and microplasma welding processes - very easy , quickly and worthless.
1993–1995 - Studied welding processes and equipment in Israel (manual, argon and CO 2 welding, microplasma); studied AutoCAD, designed a universal plasma head.
1987-1993 - Built the unique equipment for welding in various positions at speeds up to 400 m/h and multi-purpose plasma torch; worked out technologies of welding of magnetic cores, bellows, short tubes and lap joints of low carbon steels without use of filler material; made original elements of welding power sources, one plasma set (AMC-1) together with a new plasma torch (that has an adjustable electrode) awarded a silver medal at the Jubilee USSR NEA Exhibition. Developed some welding methods, devices and filler materials. Invented a simple set for plasma spot welding, made some investigations in combined processes.
1976–1987 - Researched the weldability of Pt-alloys for glass melting vessels; developed the special types of welds for glass melting vessels and some their structures, methods of carrying-out heterogeneous junction Pd-Ag and Fe-Ni alloys and filler materials for these aims; took part in creation of high-productivity blocks of super-pure hydrogen purification, worked-out welding of horizontal flange seams of vertical plane with gaps and displacements of edges exceeding their width – without filler material (for goods like canisters); supported the dissertation-PhD.
Developed improved technologies and devices for diaphragm bellows producing, including such with prolongated working life, proposed the rational connections of edge welded bellows to an armature.The rational edge weld configuration was included to the USSR Bellows.
1968–1976 - Investigated the weldability of Pd-Ag alloys; developed the theory of formation of an edge weld of a foil; developed technologies of manufacturing membrane constructions, bellows, strips, thermo-couples, ampoules, shells, lattice elements, chemical current sources, sensors. Elaborated on assemble attachments, welding and mechanical tests, worked in the field of materials engineering, metallography.
1966 - Carried-out a unique welding repair of a crankshaft on a guillotine shears (made in Germany) which was cracked in two parts, crankshaft had the length 1,5m and the maximum diameter 350 mm , its material was a steel with 0,35% C.
1964–1965 - Introduced welding of some industrial goods 1- 2 mm thick, modernized TIG-set for spot arc welding, improved the quality of arms factory welded goods.
1958–1963 - Bryansk Institute of Transport Machinery - M.Sc – Engineer in Mechanics and Welding.
