How thick will a laser welder weld?

The thickness that a fiber laser welder can weld depends on the power of the fiber laser welding machine, the type of material to be welded, the welding parameters setting and the wire feeder we using can also affect the welding thickness. Here’s a summary of the capabilities based on different power levels:

Maximum Welding Thickness by Different Laser Power

Laser PowerMaximum Welding Thickness (Stainless Steel)
1000WUp to 2 mm
1500WUp to 5 mm
2000WUp to 8 mm
3000WUp to 12 mm

Key Points:

1000W fiber laser welding machine : Capable of welding up to 2 mm thick stainless steel, with higher speeds achievable.

1500W fiber laser welding machine: This power level allows for welding up to 5 mm thick materials effectively.

2000W fiber laser welding machine: The most powerful option listed, capable of welding up to 8 mm thick stainless steel, providing sufficient energy for deep penetration.

3000W fiber laser welding machine:‌The thickness of stainless steel that can be welded by the 3000W laser welding machine ranges from 5mm to 12mm‌. Specifically, the 3000W laser welding machine is usually able to weld stainless steel plates with a thickness of 5mm to 12mm, and is suitable for welding some thicker metal materials, such as common materials such as carbon steel and stainless steel.‌

Factors Affect Welding Thickness:

Laser Power: Higher power allows for thicker materials.

Material Type: Different materials (e.g., stainless steel, brass, aluminum,gold, silver….) have varying thickness capabilities.

Welding Parameters: Spot size, irradiation time, and cooling effect also play crucial roles in determining the maximum thickness that can be welded.

The welding process also depends on the material type; for instance, carbon steel and titanium require distinct parameters for effective welding.

Welding suggestions:

For materials thinner than 1.0mm, lower power settings are sufficient, while materials ranging from 1.0mm to 5.0mm require medium power settings. Thicker materials generally necessitate higher power levels and may require multiple passes for optimal results.

In summary, while handheld fiber laser welding machine are limited to around 8mm for stainless steel, industrial systems can achieve much greater thicknesses depending on their power and configuration.
