The laser energy necessary for welding can be presented to parts in the form of either a spot or a line. Spot or contour welding refers to the use of a circular spot of laser energy to traverse a preprogrammed contour path and create a weld.
The concept behind fiber optics is relatively simple. Just take a flashlight and shine it through one end of a transparent tube of glass or plastic in a dark room. Of course, it’s a lot more complicated than that.
Active alignment: the process of coupling a light source, such as a diode laser, with the input end of an optical fiber to determine the optimal position of the component
Ultrasonic welders are available in several different frequencies, such as 15, 20 and 40 kilohertz, and a variety of power supplies, such as 1,000, 1,500, 2,000, 3,000 and 4,000 watts. It’s important to select the optimal frequency and power for your application.
