Metal Laser Marking is an electro-optical technique that uses a directed-light beam to create precise metal patterns using controlled laser energy. The fine laser-cut provides quick laser services at the stencils and templates stage through advanced production techniques for many application areas such as jewelry, metal art, electronics, and others. Marking applications range from metal stamping, die-cutting, embossing, engraving, laminating, and plating.
For Laser Marking, the basic operating principle is applying a pulsed beam of light onto the target surface to create the desired engraved pattern. This may be accomplished by using the fine laser marking beam coupled with heat treatment for metal surfaces. During the annealing process, the substrate metal is heated to a temperature above induction temperatures. This process allows the metal to be annealed while the laser marking laser beam is positioned between the annealed substrate and the working area.
In Laser Marking, the three major types of this process are Steel (stainless steel), Etching, and Acoustic Appraising. Steel (stainless steel) Metal Laser Marking is used to etch or design on the surface of steel by applying a thin layer of gas. This is followed by selective laser ablation, which is used to clean the working area from dust or debris.
Yage Laser Marking is the most popular technique used worldwide for substrate laser marking applications. This technique uses high pulse laser technology to produce high peak power light focused on the part or surface being marked. High pulse energy is necessary because it allows for the fast pulse length in the micro backlashes compared to other marking methods such as spot and scalloped processes. Yage lasers also offer a high-quality dot matrix LED array for substrate branding applications. Yag lasers have a very high incident rate and are suitable for most jobs, including coating automotive, industrial, marine, and household products.
Acoustic Appraising is used for detecting defects and for testing component quality. Various industries rely on this method for detecting defects in components before they are sent to customers for production or consumption. The latest versions of this process use acoustic wave technology. Acoustic testing can identify the presence of buried air bubbles and cavities. It can also detect any defects in the thickness of component sections. This makes it essential for various industries to use the correct type of laser marker for these applications.
We will look at the final type of marking technique that uses a combination of high peak power, rapid pulse rates, depth penetration, and fast pulse durations. This last method is called Acoustic Beam Testing, which is also known as acoustic beam spray coating. This method uses a combination of high peak power, rapid pulse rates, and depth penetration for maximum effectiveness and reliability. We have already mentioned some of the other techniques scanning, optical flow, and resistive and non-resistant coating.
Although Laser Marking has many advantages over most other forms of marking, it does come with certain disadvantages. One of the primary disadvantages of using Laser Marking is that it requires exact wavelength configurations. Marking with a metal material that has an exact wavelength is very difficult, if not impossible. In addition, larger wavelengths require larger holes, although, with the help of suitable quality beam spot sizes, precise positioning with Laser Marking can still be achieved.
Another disadvantage of Laser marking is that the energy used causes a significant amount of heat. It can cause a meltdown of plastics and some metals, although it is not usually feasible. Some of the other common materials that suffer meltdowns are ceramics and polymers. The other disadvantage of this procedure is that it can only be used on softer materials like metals. With various kinds of machines, it may not be possible to engrave all kinds of materials. Metal laser markings engraving machines are one of the best and most reliable methods of marking materials resistant to this process. Click here for more: https://www.laserbondingtech.com/
