Product Details

Equipment Introduction

The LWF series fiber laser welding machine is different from traditional solid-state lasers that use crystal rods as the laser medium. The laser medium of fiber lasers is a long ytterbium doped double clad fiber, which is pumped by high-power multimode laser diodes. The generated laser has the characteristics of good beam quality and high energy, and has many unique advantages in the field of laser welding applications. This device has the following advantages:

Good beam quality, high energy

Suitable for high-speed and high-precision welding. Compared with traditional lamp pumped laser welding machines, the LWF series fiber laser welding machine has the characteristics of good beam quality and small divergence angle. It has great advantages in welding efficiency and weld seam effect.

Compact size, achieving portability

The LWF series is lightweight and compact, saving space and facilitating transportation compared to lamp pumped solid-state machines. The laser transmission fiber can reach up to 15m, adapting to changing processing locations.

Stable power & high reliability

Energy fluctuations below 2% ensure stable laser welding quality. The average usage time of laser pump sources can reach over 50,000 hours, which is about 100 times that of lamp pumped laser welding machines.

High efficiency & low consumption

The electro-optical conversion efficiency is as high as 30%. The overall power of the FRZ-LWF500C is only 4000W, which is 1/3 of the ordinary 300W lamp pumped solid-state machine. Average energy consumption is about 1/10 of ordinary welding machines.

Control system

Using dedicated motion control software, the electric worktable is controlled to complete work according to the set trajectory. Options include a vibrating mirror worktable, robot, or line following automation design.
