Preface
The thickness that a laser welding machine can handle is mainly determined by the laser power, the material properties, and the welding speed. Unlike traditional welding methods, laser welding can achieve deep penetration welding while maintaining a very small heat affected zone and a very low deformation rate. Dynalasers precisely offers this highly efficient and stable solution. So, how thick of materials can a laser welding machine weld? We will delve into this in detail next.
What Determines Laser Welding Thickness
When discussing the welding thickness of the laser welding machine, several key factors need to be taken into consideration. Understanding these factors not only helps you optimize the welding process, but also enables you to select the most suitable equipment based on your actual needs.
Laser Power
Laser power is the key factor determining the welding thickness. The higher the power, the deeper the laser beam can penetrate the material. For instance, a 1000W laser is suitable for welding thin plates that are a few millimeters thick, while a 3000W system can handle thicker metals. Power determines the heat input, and the amount of heat directly affects the welding depth.
Material Type
The response of different metals to laser welding varies greatly. For instance, at the same power level, the welding depth of stainless steel is usually deeper than that of aluminum because aluminum dissipates heat more quickly. The limit to the material thickness that can be achieved depends on these characteristics, so knowing the type of metal being used is extremely crucial.
Welding Speed
A slower speed enables the heat to accumulate more thoroughly, thereby increasing the penetration depth. However, if the speed is too slow, problems such as burn-through or deformation may occur. Therefore, during the welding process, finding the optimal balance between speed and power is the key to achieving the desired welding thickness.
Beam Focus and Spot Size
The size of the light spot and the degree of focusing play a crucial role in laser welding. When the light spot is smaller and the focus is tighter, the laser’s energy is highly concentrated, enabling it to heat the material to a molten or vaporized state in an extremely short period of time. This high energy density allows the laser to easily “penetrate” thicker metals and achieve deeper welding penetration.
Shielding Gas
The type and flow rate of the gas will affect heat transfer and the stability of the molten pool, thereby indirectly influencing the welding thickness. Correct use of the shielding gas can ensure a clean and strong weld, especially when welding active metals such as aluminum or titanium, the effect is more obvious.
How Thick Can a Laser Welder Weld
When discussing the thickness of laser welding, the two most influential factors are laser power and material type. Besides, the choice of equipment is also crucial. Each type of equipment has its own advantages and limitations, and the key lies in matching it according to actual needs.
Thickness Ranges by Laser Power
Here’s a quick guide to typical welding thicknesses you can expect based on laser power:
| Laser Power | Typical Welding Thickness Range (Steel) |
| 1000W | Up to 3 mm (0.12 inches) |
| 1500W | 3 to 5 mm (0.12 to 0.20 inches) |
| 2000W | 5 to 8 mm (0.20 to 0.31 inches) |
| 3000W | 8 to 12 mm (0.31 to 0.47 inches) |
These welding thicknesses will vary depending on the material type (such as stainless steel, aluminum or other metals) and the welding speed. For thicker materials, it is usually necessary to perform layer-by-layer or multiple welds to ensure a strong weld seam and maintain high quality.
Handheld vs Industrial Laser Welders Thickness Capabilities
Handheld Laser Welders Thickness Range
Handheld laser welding machines are usually capable of welding materials with a thickness ranging from 0.5 millimeters to approximately 3 millimeters. They are highly suitable for processing, repairing and spot welding thin metal sheets, as these tasks have high requirements for flexibility and ease of use. Dynalasers laser welding machine S series offers a variety of lightweight handheld models. These devices have excellent portability and ease of operation, making them ideal for on-site repairs, routine maintenance, and light manufacturing tasks.
Industrial Laser Welding Systems Thickness Range
In contrast, industrial laser welding machines are specifically designed for high-strength and heavy-load applications. They can weld thicker materials, typically ranging from 1 millimeter to 12 millimeters or even thicker, and are highly suitable for production lines, automotive manufacturing, and large-scale production. The industrial models D series and M series of Dynalasers laser welders offer higher laser power and advanced control functions, enabling stable welding of thicker metals such as stainless steel and aluminum.
Limitations to Consider
- Industrial welding machines are large in size and require fixed installation, often occupying a relatively large workshop space. This means that they suffer from reduced mobility and flexibility. In contrast, handheld welding machines can be easily moved and are more suitable for quick repairs on-site or operation in confined spaces.
- Industrial equipment is highly complex in terms of functionality and requires precise parameter adjustments. Therefore, higher skills are demanded from the operators. Usually, systematic training is needed to master the equipment proficiently, but this is often not practical in emergency repairs or small-scale projects.
- Although industrial welding machines can provide stable and repeatable high-quality welding in large-scale production, they are not the best choice in terms of flexibility and quick response. This is why many enterprises will equip both handheld and industrial laser welding machines to cater to different application scenarios.
Dynalasers offers a range of models designed to handle different thicknesses efficiently, whether you’re working with thin stainless steel sheets or thicker metal parts.
