Laser Beam Welding
of light energy is converted to thermal energy. Surface melting occurs and progresses through the weld joint by thermal conductance. For welding, beam energy is maintained below the vaporization temperature of the weld joint material. For hole drilling or cutting vaporization is required. Because

Laser Drilling is a Key Process for Refurbishing Turbine-Engine Components
lasers can handle nonmetallic parts. Different processes include: Percussion drilling, most frequently used, generates a hole with only the laser’s focused beam. A single pulse or series of pulses remove the material in the beam path, with coaxial-gas flow helping clear debris. The process

New "window" of opportunity for e-beam welding
Window. Beam temperatures exceeding 10,000 C produce the brilliant, blue-white light. The beam source is about 3-ft high and 15 in. in diameter so it is able to mount on a robot arm or be fitted to multiaxis NC machinery. Besides welding, the same system will be capable of drilling small holes

for welding fuel elements for the. nuclear industry. Prior to this time, Steigerwald (in Germany) had been. experimenting with electron beam for machining (e.g., drilling and. cutting) purposes. Carl Zeiss, another German scientist also. contributed to the promotion of electron welding and was the first

Multiaxis Lasers Come Of Age
pulsing the laser as a function of axis position to increase drilling speed. Machining holes and other features with multiaxis lasers enhances aircraft-engine performance and fuel efficiency. The drill-on-the-fly feature reduces the time to machine a typical hole from about 5 to 1 sec. Lasers quickly

Ins and Outs of ID/OD Comparative Gaging
Circles are the most frequently produced machined form. Generated by many different processes- including turning, milling, centerless grinding, boring, reaming and drilling- there are, correspondingly, a wide variety of gaging methods used to measure inside and outside diameters. At the low end
