Three Common Questions Concerning Laser Welding in Sheet Metal Fabrication

Many sheet metal fabrication shops still hesitate to invest in laser welding. They are missing out on the numerous competitive advantages and opportunities that it offers over conventional welding processes. Here are some insights that they need to know.

Lasers Handle Cutting and Welding of Complex Parts

The Morgan 3 Wheeler car build in the Premier shop, which used AutoForm simulation to arrive at the 2D shape for each blank, which was then laser cut ready for forming. The shop produced 1,500 sets of bodywork panels at the high speed of laser cutting to keep costs down.
This shop welded the seam and cut 100 million holes in 12,100 torches – in six months. That's not all. Check out the automotive parts they're making.

Electron Beam Welding vs. Laser Welding

Electron Beam Welding is ideal for applications that require a very precise, clean weld with minimal heating of the material outside the primary area of the weld. EB Welding is also excellent for joining dissimilar and hard to weld metals.
A comparison of the two processes by application and cost.

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.

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.
