The use of Electron Beam Welding in Turbomachinery Manufacturing
As demands for higher performance migrated from aircraft engines to land based gas turbines the need for EB welding came along also. The transfer of EB welding processes from relatively thin section components in aircraft turbines to land based aero derivative turbines is straightforward since the basic design and function of both aero and aero derivative components are the same or similar. How...
متن کاملPlasma Charge Current for Controlling and Monitoring Electron Beam Welding with Beam Oscillation
Electron beam welding (EBW) shows certain problems with the control of focus regime. The electron beam focus can be controlled in electron-beam welding based on the parameters of a secondary signal. In this case, the parameters like secondary emissions and focus coil current have extreme relationships. There are two values of focus coil current which provide equal value signal parameters. There...
متن کامل3 . Spatial - Phase - Locked Electron - Beam
Our research in spatial-phase-locked electron-beam lithography (SPLEBL) is aimed at reducing pattern-placement errors in electron-beam-lithography systems to the 1 nm level. Such high precision is essential for a variety of future lithographic applications. SPLEBL is currently the only approach capable of achieving such accuracy. As shown in Figure 1, SPLEBL uses a periodic signal, derived from...
متن کاملImproving Laser Beam Welding Efficiency
Laser beam welding is becoming widely used in many industrial applications. This paper reviews recent research conducted on the performance, potential and problems of thick section butt joint laser welding. Common defects that occur in laser beam welding with high power laser welding are discussed and possible solutions proposed. Methods of welding process efficiency improvement are analyzed.
متن کاملTitanium Welding Technology
In order to establish titanium welding technology TIG arc weldability and MIG arc weldability were surveyed. For TIG arc weldability influence of arc length and thickness to proper region of welding condition became obvious. For MIG arc weldability a new method to defend wandering phenomenon was developed.
