The Next Big Thing in Sheet Metal Fabrication

Laser welding and aluminum cable cover with a TruLaser robot. With laser welding, overall tolerance, accuracy and finished part quality can be improved by either forming all sides individually or bending two pieces such that the bends on one part create the sides of the box and the second part creates the ends.
The competitive advantages of laser welding are generating all sorts of excitement as new advancements have minimized the initial investment required and offer a more affordable entry for job shops. 

Laser Beam Delivery and Focusing Optics

For lasers of a certain wavelength, around 1 micron (corresponding to neodymium-doped yttrium aluminum garnet (Nd:YAG), fiber and diode), the laser can be delivered to the workstation by a flexible fiber optic cable. This offers great convenience for integration because the flexible fiber can be routed by whichever orientation is best for the system.
Some tips and best practices for maintaining a high production yield in micro welding.

Using Laser Beam Welding with Electron Beam Welding for Complex Geometry and Superior Metallurgy

Using both laser and electron beam technologies in a single facility can streamline the fusing of complex geometries that are required on parts such as sensors, medical devices, and products that require a sealed vacuum within the finished part.

Laser Welding Puts Automotive Industry “On A Diet”

The level of innovation behind weight-reduction efforts is exemplified in passenger car transmissions that are manufactured by the millions in volume and, as such, require optimized designs that provide an economic advantage to the manufacturer. With an already great design, is it possible to make them even lighter? This automated system from EMAG shows how.

Powerful Lasers are Ideal for Plastic or Thin Gauge Metal Welding

The TruDiode 301 supplies 300 watts of laser power to the work piece. Wavelength range is between 920 Nm to 970 Nm with CW or modulated CW up to 3kHz.
TruDiode 151 and TruDiode 301 lasers from TRUMPF are more powerful and efficient, yet smaller than previous TruDiode lasers, producing wavelengths that range between 920 Nm to 970 Nm.
