Principles and Core Advantages of Scanner Laser Welding

Laser Scanner Welding is a technology that achieves dynamic scanning welding through robot-controlled laser galvanometers. Its core lies in the "welding while moving" mode, which breaks the efficiency bottleneck of traditional point-by-point welding. By virtue of the three-channel beam splitting technology (visible light, laser reflected light, and infrared light), Lyric’s system can real-time monitor over 20 types of welding defects such as molten pool morphology, power stability, and material contamination, realizing non-destructive testing with micron-level precision.

The core advantages of Lyric's Laser Scanner Welding are embodied in three aspects: efficiency, flexibility, and reliability.

Its scanning welding speed reaches 80–100 mm/s with repeat positioning accuracy of ±0.05 mm.The single-weld cycle time is reduced to 3 seconds per weld point, increasing efficiency by 17% compared to traditional processes.

Meanwhile, the non-contact welding capability adapts to complex curved workpieces, reducing overlap edge width and lowering material consumption by 15%.

Furthermore, through Position Synchronized Output (PSO) laser energy control technology, the system maintains consistent welding quality during high-speed dynamics, solving persistent industry challenges such as corner welding deformation and cold welding.
