• Electro-optical conversion efficiency >43% (competitors' 915 nm pumping <32%)
• 3 kW @ 20 μm core diameter, energy density reaching ~4×10⁹ W/cm², far exceeding the copper welding initiation threshold (≥120 MW/cm²)
• Shorter active fiber length reduces nonlinear effects and improves beam quality

AI Welding Consistency System

• Laser power fluctuation <±1.5% (industry standard ±3–5%; xx Laser's precision is 2× ahead)
• Modulation response time <10 μs

Copper is particularly sensitive to joint design, copper grade, surface condition, laser source, spot size, focal position, welding speed and filler wire. 

A machine that produces a beautiful 3 mm copper weld in a demonstration may perform very differently on your actual parts.
