Industrial Laser System – Laser Welding Machine
Nd : YAG Laser Welding Machine
In today’s competitive industrial landscape, precision and reliability are not optional—they’re essential. Whether you’re producing complex automotive components, miniaturised medical devices, or mission-critical aerospace assemblies, every weld counts.
The Nd:YAG Laser Welding Machine, based on Neodymium-doped Yttrium Aluminium Garnet (Nd:YAG) laser technology, is engineered for high-precision, low-distortion welding of metals. Its capability to deliver clean, concentrated energy pulses with pinpoint accuracy makes it the gold standard for high-precision joining across a variety of industries.
Understanding YAG Laser Welding Machine
Nd:YAG Laser Welding Machine uses a solid-state laser medium—Neodymium-doped Yttrium Aluminum Garnet—to emit a tightly focused beam of infrared light (1064 nm). The beam’s high energy density allows for:
- Deep penetration welding
- Small heat-affected zones (HAZ)
- Ultra-fine weld seams
- Precision joining of dissimilar or micro-scale components
YAG lasers are particularly useful in pulsed mode, where rapid heating and cooling cycles allow for micro-welding of delicate parts without structural damage.
