Fiber laser welding machine: principle, application and development trend analysis

With the rapid development of technology, the application of laser technology in industrial manufacturing is becoming increasingly widespread. Among them, fiber laser welding machines have emerged in the field of welding due to their high efficiency, precision, and energy saving characteristics, and have gradually become key equipment in modern industry. This article will provide an in-depth analysis of the principles, applications, and development trends of fiber laser welding machines.

1、 The principle of fiber laser welding machine

Fiber laser welding machine utilizes the high energy density characteristics of laser beam to focus the laser beam on the part of the workpiece to be welded, causing the material to melt and recrystallize in a very short time, forming a welding joint. Its working principle mainly includes three steps: laser generation, transmission, and focusing. The laser generator generates a laser beam, which is transmitted through an optical fiber to the working head, and then focused onto the small area required for welding through a focusing lens, achieving precise welding operations.
