In this article, we will explore the multifaceted applications of laser cutting technology in 10 major industries.

What is Laser Cutting?

Laser cutting is a precise method for cutting a variety of materials using a high-powered laser. In this process, a laser source directs a laser beam to the materials to be cut. 

The beam cuts something by focusing intense heat onto very small points, either melting, burning, or vaporizing away the material. It allows for very clean and precise cuts, with a high level of control over the cutting path and speed.

There are a few main ways that laser cutting works:

• CO2 laser cutting uses carbon dioxide gas to generate the beam. These can cut thicker materials, like stainless steel and aluminum.
• Fiber laser cutting delivers the beam through an optic fiber. They can cut a range of materials but tend to be more expensive.
• Solid state lasers use a crystal to generate the beam and are commonly used on plastics and aluminum alloys.

Laser cutting machines are computerized numerical control or CNC machines, meaning the laser follows pre-programmed patterns. For this reason, they can cut complex shapes and detailed patterns with a high degree of accuracy.

Laser cutters are found in many industries like manufacturing, shipbuilding, automotive, textile, and more. Their precision makes them suitable for projects requiring intricate cuts and elaborate designs.

In short, laser cutting enables the aerospace industry to manufacture lighter, stronger, and more precise parts for modern aircraft and space vehicles. 

4. Nuclear Industry

One of the main applications of laser cutting in this sector is dismantling and demolishing nuclear power plants that have reached the end of their life cycles. 

Thick steel reactor components require precision cutting, which lasers can provide faster and more accurately than other methods. It reduces the cost of taking these plants apart. 

Within active nuclear plants, lasers are utilized for maintenance and repairs. Rather than removing large sections of worn components, a laser can precisely cut out specific parts, like bellow lips, coolant channels, or pressure tubes. It’s also well-suited for remote cutting of radioactive materials underwater or in hazardous environments.

5. Machinery Manufacturing

Laser cutting is widely used in machinery manufacturing. It can cut steel, aluminum, and titanium with accuracy for machine parts and components. It’s an effective method for cutting heavy gauge steel or fine‐tuning lightweight metals. With this technology, you can manufacture everything from large industrial machines to small parts for technical applications. 

The ability to adapt to different material thicknesses without losing precision is a core benefit of this method. Machinery makers use it for its consistency in cutting various metals for diverse needs. 

6. Steel Industry

Laser cutting has many uses in the steel fabrication industry. It can cut intricate shapes and patterns out of steel sheets with amazing precision. This makes it ideal for producing steel frameworks and architectural elements. 

The technique is also suitable for larger scale structural steel projects for things like bridges, tunnels, and building frameworks.

Some specific applications include cutting connection plates and base plates for construction. Lasers slice through different types of steel, like stainless steel and mild steel, leaving an extremely small kerf width, which minimizes material waste.

Using laser over manual methods in this industry ensures worker safety. It’s also better than alternatives like plasma cutting for achieving tighter tolerances. 

7. Textile Industry

One primary use of laser cutting in this industry is cutting complicated fabric patterns for garment production. This method gives designers far more freedom to experiment with complex designs. They can cut elaborate shapes in a wide range of materials, from lightweight cotton to tough leather. 

Beyond pattern cutting, laser technology is useful for perforating fabrics. Sportswear and outdoor apparel brands commonly use perforated materials to increase breathability. 

Backpack manufacturers laser cut ventilation holes into lightweight materials. The armor industry also employs perforation, such as with bulletproof vests. Leather goods makers take advantage of laser etching for logos and other precise engraved markings. 

8. Petroleum Industry

The petroleum industry uses laser cutting technique for: 

• Drilling underground 
• Cutting heavy metals
• Cladding materials with a protective coating
• Engraving machinery

With this technique, manufacturers create heavy-duty slotted liners that separate oil from sediments in wells. These liners were traditionally made through diffusion-cooled CO2 slab lasers but modern kilowatt fiber lasers now allow for faster and more precise cutting. Lasers can perform both piercing and continuous cutting in one step for closed features like slots, maintaining a consistent cut width.

Beyond liners, lasers are used for cutting metals throughout oil rig machinery. Other laser applications include drilling through rock more quickly than mechanical methods, debris removal in wells, providing corrosion resistant cladding on equipment, and permanent marking for identification.

9. Communication Storage

In communication storage technologies, laser cutting’s role is rather indirect. It’s not used in making hard drives, servers, or cloud storage. However, you can see its use in prototyping new storage solutions. 

The method allows engineers to create precise, customized enclosures and components with great speed and flexibility. This enables rapid iteration as designs evolve. Quick modification of parts in response to testing helps accelerate the engineering process.
