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.

Super Pulse Technology (SPT) Delivers high-energy density in short pulses for superior penetration with minimal thermal distortion. Ideal for micro-welding applications.

Detachable Display & Flexible Joystick Intuitive user interface for on-the-fly control and real-time process feedback.

Advanced Motion Control Includes programmable motorised XYZ axis, rotary fixtures, and swivelling telescope optics for complex weld geometries.

Real-Time Monitoring Remote diagnostics and onboard software offer live monitoring of laser parameters, lamp condition, cooling water quality, and safety interlocks.

Integration-Ready Design CNC-ready with Sigma Pro software—allows G-code import, 4-axis synchronisation, and automated production sequencing.

Benefits of Using YAG Laser Welding Machines

Reduced Heat-Affected Zone (HAZ) Short, focused pulses ensure rapid heat dissipation, preserving surrounding material and reducing warping.

Enhanced Weld Quality Minimal spatter, clean bead formation, and deep penetration create structurally superior welds.

Increased Productivity High pulse frequency (up to 100 Hz) enables faster welding cycles, while repeatable automation ensures process consistency.

Versatile Material Compatibility Compatible with stainless steel, titanium, aluminium, nickel alloys, and more. Weld dissimilar metals with precision.

Low Operational Costs Minimal consumables, reduced material waste, and lower maintenance overhead make this a cost-effective solution over time.
