Automated Electron Beam Welding Systems

PWT is offering the following automated Electron Beam (EB) Welders:

• Sciaky Electron Beam 3-Axis Welding System (refurbished)
• Larger Electron Beam 5 & 6-Axis Welding Systems Can Be Made Available

   Sciaky Electron Beam 3-Axis Welding System (refurbished)

(select to see larger image)	PWT has a refurbished Sciaky computer controlled 3-axis, 36"x36"x36", 60KV Electron Beam Welding machine, ready to be installed on the customer's shop floor. The machine footprint is 22' x 13'.	(select to see larger image)

The machine includes the following packages:
	Package I - Control Cabinets. The machine includes a control cabinet with associated Mark VII control printed circuit boards, operator console, and power distribution cabinet.
	Package II - Upgraded Vacuum System. The machine possesses two new vacuum gauge systems, one for the chamber and one for the gun to interface with the existing Mark VII control, including Televac vacuum gauges (calibrated to NIST standards) and troubleshooting simulators. The machine has chamber and gun turbo pumps for high vacuum conditions.	(select to see larger image)
	Package III - Axis System. The machine possesses a three-axis ("X", "Y", and rotary) servo drive system complete with drives, motors, and encoders. The encoders provide feedback to the computer control for accurate positioning and speed control.
	Package IV - Upgraded High Speed Scanner System. The high speed (2500 Hz) scanner system will consist of a Scanner Booster Amplifier and Scanner Booster Simulator, used for troubleshooting the Scanner Booster Amplifier circuit.
	Package V - High Voltage System. The machine possesses a 15KW (60KV, 250ma) high voltage tank and single transistor solid-state AVR system. PWT's transistor pack uses one IGBT (Isolated Gate Bridge Transistor), the latest generation in power transistors. See a further description of the single transistor AVR under "Solid State AVR System" on our EBW Components page.
	Package VI - Computer Control System. The computer control consists of an S120 Data General computer, its associated printed circuit boards, a CRT monitor, and all necessary input/output (I/O) interface printed circuit boards/components. A full computer cabinet with I/O rack shall house the computer/electrical components. A rack mounted CNC mini-file system, which utilizes 3 1/2 inch, 1.44 Megabyte diskettes is included. An operator's pendant, with all necessary controls, is provided.
	Package VII - Initial Machine Startup. We will ensure the electrical and gas supplies are connected adequately, start the machine up, and perform a preventative maintenance (PM) check, including calibration of the critical process parameters, to ensure the machine will meet new machine performance requirements.
