Lasers have been used in manufacturing for a long time and the newer generations of lasers are even more versatile. If you are considering taking advantage of the newer efficient high-powered diode lasers, it is important to know how they are used.

Industrial Uses for Lasers

High-powered diode lasers are most often used for the cutting of mild steel, stainless steel, and other types of metals. While used in many industries, they are primarily used in the automotive industry.

The Power of a Laser

There are various lasers that can be used in manufacturing applications, and they vary not only in terms of the strength of the laser beam but also the quality of the beam as measured by the beam parameter product. 

The Next Generation in Lasers

Newer generations of lasers have been easier to maintain and service. Commercialized diode lasers are much more efficient and have a beam quality that allows for the laser to be used for more than just welding. They can also be used in home applications. As a result, first-generation lasers are considered obsolete. 

The challenge with developing lasers is to achieve the maximum level of brightness without sacrificing size, efficiency, persistence, and cost. Fortunately, wavelength beam combining has made this possible and has opened up more commercial applications for lasers.

Lasers and Welding

Gaussian beams are avoided and flat-top profiles are usually preferred when engaging in laser cutting. With laser cutting, the primary objective is to remove material. After the material has vaporized, it must be allowed to outgas so that there is no interference with the process of cutting through the material. Otherwise, you will not have a cut that is as clean as needed. 

Fortunately, a focused gas jet can be used alongside a short laser pulse to prevent the vaporized material from being inside the cut. Otherwise, the material will build up inside the cut and will cause unwanted heating. You will want to prevent oxidation during the welding process. This will ensure that the weld is strong and reliable. 

The Beam Shape

Another important part of laser welding is the beam shape. This is because you will want the beam focused on the tightest spot possible. This allows for the most precise cut so you can achieve the results you're aiming for. Because of this, you will want a high-power diode laser system that allows you to adjust the beam width to meet your needs.
