The development history of handheld laser welding

As we all know, the laser has the characteristics of "good monochromaticity, high directivity, high coherence, and high brightness". Laser welding is also a process in which the light emitted by the laser is used. After optical processing, the laser beam is focused to generate a beam of huge energy, which is irradiated to the welding part of the material to be welded, and it is melted to form a permanent connection process.

More than ten years ago, the main laser used for laser welding in China was the solid-state lamp pumping laser, which has large energy consumption and volume. To solve the shortcomings of its light path direction being difficult to change, fiber-optic transmission laser welding equipment was introduced. Then inspired by foreign handheld optical fiber transmission equipment, he produced his own handheld laser welding machine.

This is the "first generation of handheld laser welding machine" in China. Due to the flexible transmission of optical fibers, the operation convenience of the welding equipment has been greatly improved.

So which was the "first generation of hand-held laser welding machine" and argon arc welding at that time? Everyone likes to ask this question all the time. Strictly speaking, these are two types of equipment, and their working principles are different, so we cannot simply compare them. Let's take a look at where each is applicable.
