Can Fiber Laser Cut Through Thick Steel?

Laser cutting is a powerful tool for fabricating and manufacturing steel components, but it does have its limitations. While this technology excels in producing precise cuts, there are certain thicknesses that it may struggle with, potentially resulting in a compromised finish.

In this article, Krrass Machinery explores the limitations of laser cutting, focusing on how factors such as wattage and metal type affect the maximum thickness that can be effectively cut.

Laser Cutting Thickness Limitations

Laser cutters are precision tools capable of slicing through various thicknesses of steel, but their cutting capabilities are not without constraints. The maximum thickness of steel that a laser cutter can handle largely depends on the power of the laser and the specific type of steel being cut.

Thicker steel necessitates higher laser power, which can slow down cutting speeds and increase heat generation. This added heat may affect the quality of the cut, leading to potential warping or melting of the steel. To manage these issues, specialized cutting techniques and cooling systems might be required.

Additionally, the reflective nature of certain steel types, such as stainless steel, can present challenges. The reflective surface can cause the laser beam to bounce off, complicating the cutting process for thicker stainless steel sheets.

General Laser Cutting Thickness Limits Based on Wattage

Laser cutting capabilities are influenced by the power of the laser, which determines how much heat is generated to melt or vaporize the material being cut. Higher wattage lasers produce more intense beams, allowing them to cut through thicker materials. The appropriate wattage for cutting various materials depends on the type of metal and its thickness.

For instance, a lower-wattage laser may struggle with cutting thicker stainless steel sheets. As a general guide, the maximum cutting thickness for different metals based on laser wattage is as follows:

3 Terms in Fiber Laser Cutting

Marking Area

The term "marking area" refers to the space within which a fiber laser system can etch codes, images, and markings. Similar to the "print height" in continuous inkjet and thermal inkjet printers, the marking area defines the maximum size of the code or image that a laser system can create.

In addition to determining the maximum size of the markings, the marking area is crucial for applications where multiple substrates need to be processed in a single operation. For instance, when applying lot codes to food cans, having a large marking area combined with an appropriate production line setup allows for efficient marking of several cans at once.

Marking areas vary widely among different fiber laser systems, ranging from a few square millimeters to several hundred square millimeters. There is no one-size-fits-all standard, so it is advisable to consult with an expert to select a marking area that best suits your specific needs.

Marking Speed

When selecting a fiber laser system for marking and engraving, it is crucial to choose one that aligns with your production demands.

For high-volume operations, such as bottling lines, the marking system must keep pace with the speed of your production line. Fiber laser systems come with varying speed capabilities to accommodate different production setups. The fastest systems available can handle line speeds exceeding 900 meters per minute (m/min). However, most manufacturing and packaging facilities find that a system with a speed range of 200-600 m/min suffices for their needs.

Another key performance metric is characters per second (CPS), which indicates the number of numbers, letters, and symbols a fiber laser system can produce in one second. This metric is especially important for applications involving extensive text or alphanumeric codes, as it determines whether the system can handle your coding requirements efficiently.

Typically, industrial fiber laser systems are rated at around 2,000 characters per second. Keep in mind that this figure can vary based on factors such as code complexity and the material of the substrate. To ensure the chosen system fits your specific needs, consult with the manufacturer or supplier to discuss how their laser system will integrate with your production processes.

Marking Precision

Marking precision refers to how accurately a fiber laser system can create marks on substrates, ensuring that the codes or designs match the intended size, position, and shape without deviation. High precision ensures that markings are clear, correctly aligned, and consistently produced, while lower precision can lead to issues such as distorted characters, misplaced markings, and uneven coloring.

Unlike metrics such as marking speed or marking area, marking precision does not have a standardized measurement. Instead, it is influenced by several factors:

• Optical System Quality: The performance of lenses, mirrors, and other optical components affects precision.
• Motion Control System Quality: The accuracy of motors and controllers that guide the laser also plays a crucial role.
• Software Sophistication: Advanced software can enhance precision by providing more accurate control over marking parameters.
• Overall System Design: The overall construction and design of the laser system impact its ability to maintain precision.

Additionally, the environment of your facility and the type of substrate used can affect the precision of the laser markings. To ensure you select a system that meets your precision requirements, consult with suppliers about the accuracy of their systems and consider how your specific environment and materials might influence performance.

How to Choose the Right Laser Power

When selecting a fiber laser cutting machine, understanding the relationship between laser power and cutting capability is essential. Fiber lasers are primarily used for cutting metal, including materials like stainless steel, carbon steel, aluminum, and brass. The thickness that can be cut increases with the laser power.

The power of fiber laser cutting machines is largely determined by the laser source. In the market, machines with power levels of 4000W and above are classified as high-power, those between 2000W and 4000W as medium-power, and those below 2000W as low-power. Currently, 2000W fiber laser cutting machines are in high demand, as they can handle most cutting tasks efficiently. Although higher power machines (above 2000W) can offer faster cutting speeds, they come at a higher cost. Laser power is one of the main factors that directly impacts the price of a laser cutting machine.

For cutting thinner stainless steel and carbon steel sheets, a low-power fiber laser cutting machine is often sufficient. These machines provide a good cutting effect while maintaining fast speeds, ensuring both work efficiency and cost savings. Therefore, it is crucial to select a laser cutting machine based on the specific metal material and thickness you intend to work with, rather than simply opting for the highest power available. However, if your cutting needs involve both thick and thin plates and you have high production capacity requirements, investing in a high-power laser cutting machine may be a more prudent choice. High-power machines can also achieve good cutting quality by adjusting the cutting speed and changing the auxiliary gas.

For example, a 1000W machine is capable of cutting carbon steel up to 8mm thick, while a 1500W machine can cut up to 12mm. In the case of stainless steel, a 1000W machine can handle thicknesses up to 4mm, while a 1500W machine can cut up to 6mm. From this, it's clear that when comparing 1000W and 1500W fiber laser cutting machines, the 1500W option is often the more sensible choice for a broader range of applications.
