Laser welding machine does not emit laser?

During the working process of the laser welding machine, the laser suddenly does not come out. Solution: Check whether the 3A safety tube of the pre-combustion board is intact and whether there is a power failure. Check whether the laser cavity is leaking.

Why cannot the laser marking reach the expected marking depth?

Reasons: ① Whether the laser output power meets the requirements. ②Whether the turn-off power of the acousto-optic switch meets the requirements. ③ Whether the optical path adjustment is accurate. ④Whether the workpiece surface is on the focal plane.
