Factory-built optical systems, automated CNC interfaces, and hand-held multi-process laser machinery for mission-critical industrial manufacturing.
Understanding beam quality (M²), peak-pulse power densities, and thermal dissipation windows for sensitive metallurgical applications.
QCW fiber lasers operate in both continuous and high-peak pulsed states. By accumulating energy over microsecond cycles, a 150W continuous laser yields up to 1500W peak power, generating a keyhole effect without saturating the base substrate with residual heat.
Ideal for heat-sensitive electronics, micro-welding in medical instruments, and high-spec injection mold edge repairs where metallurgical shrinkage or tempering must be strictly prevented.
CW laser sources emit a steady, non-fluctuating photon beam that maintains uniform molten pool convection at linear speeds reaching meters per minute. It is the premier choice for deep penetration and high structural volume manufacturing.
CW is deployed extensively across battery pack busbar consolidation, structural carbon steel assemblies, automated automotive chassis joints, and thick sheet-metal enclosures requiring robust mechanical tensile strength.
Traditional laser spots are static (0.2–0.6 mm), making them prone to bridging voids when seam tolerances fluctuate. Our digital galvanometer systems introduce high-frequency beam oscillation (Circle, Triangle, Line, Infinity patterns).
This dynamic agitation wide-spans the melt pool up to 5 mm, de-gases molten zinc, prevents spatters on galvanized metals, and dramatically improves joint shear tolerances across non-ferrous alloys.

A rigorous five-tier qualification procedure executed inside our Shenzhen application lab to guarantee defect-free parameter windows before capital deployment.
Clients send production coupons. Engineers evaluate material reflectivity, melting points, oxide coatings, and mechanical gap tolerances (Butt, Lap, Corner, T-joint) under optical profilometers.
We execute multi-pass matrix trials adjusting peak pulse width (0.2–20 ms), pulse repetition frequency (PRF), continuous power modulation, and wobble frequency to isolate the ideal plume behavior.
Sample joints undergo cross-sectional microscopy to confirm penetration depth, weld root fusion, zero micro-cracking, and grain refinement, backed by tensile pull testing and hermetic helium leak checks.
Next-generation Youmir CNC welding workstations integrate coaxially aligned infrared cameras and machine-learning plasma spectrometers. By observing molten pool spectral emission in real-time, the system automatically adjusts laser wattage microsecond-by-microsecond, eradicating blow-through and ensuring 99.98% first-pass production yields across unpredictable alloy blends.
