Welding
Welding allows parts to coalesce along their contacting surfaces by applying heat, pressure, or both, and often adding a filler material. The most common industrial welding methods are fusion processes in which workpieces are melted at their common surfaces. Solid-state welding joins parts

Shedding New Light On Tiny Packages
lasers work well for contour welding. They emit NIR radiation at wavelengths between 808 and 980 nm and produce the required 10 to 100 W. With contour welding, the laser head moves along the weld line path in either two or three dimensions. A translating stage works for 2D jobs while a robot is best

Vision in Hostile Environments
(cameras, lasers, LED's, and other items) have evolved in to fully, solid-state rugged devices, available with ever-increasing performance and lower cost. Computational devices, required for image processing algorithms, have similarly dramatically evolved. Much of this evolution has followed developments
