The distribution of thermal fields is simulated with the thermal action of the electron beam on stainless steel. To obtain data on the temperature distribution in the material, thermal loads are modeled. Two heating options ...
The results of analytical study of relationship between strength and plastic properties of a series of structural materials are presented. For this purpose the behavior of different materials during the stretching process ...
We present an approach to build of real time continuous seam finder module with waveform generator (arbitrary signal can be generated), which allows automatic coordinate correction within 2ms on the go. Module is made for ...
This paper describes a laser heated cathode gun design which uses a lanthanum hexaboride button in a diode configuration. Beam currents up to 40 mA at – 60 kV were generated by using laser powers in the range of 19 to 83 ...
Part of the mission for the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) is to develop, mature and deploy advanced manufacturing technologies in the nuclear manufacturing industry. Electron beam welding (EBW) ...
The results of electron beam right angle turn experiments in EBW setup are presented. For beam turn we use an alpha magnet and quadrupole lenses. As a result the cathode is not exposed to the vapors of the workpiece. The use ...
In directly keyhole electron beam welding of Ti/Al alloys the heterogeneous interfacial reactions were found in the weldments. The intermetallic brittle phases (e. g. Ti3Al) formed at the weld joint and affected ...
This contribution presents the solution of technological aspects in mass production of die-cast aluminium alloys as well as the design of new modules necessary for successful dealing with production. The welded parts are made ...
Welding technology for the high-speed rotor combined bandage made of dissimilar ferromagnetic and paramagnetic alloys is developed. The possibility of high-quality welded joints obtaining with the free weld root formation ...
