High Speed Aluminum Industrial Laser Welder - 300W

Product catalog summary

Introduction
Miyachi America Corporation introduces an innovative approach to laser welding, particularly for aluminum, by coupling more laser power into a smaller fiber. This results in smaller spot diameters and higher power density, essential for overcoming aluminum's reflective characteristics and achieving effective metal absorption.

Key Features of LW300AH

High-speed aluminum welding with seam weld speeds up to 40mm per second, three times faster than conventional 300 watt Nd:YAG lasers.
High power density and small spot diameter for deep, crack-free welds with minimal heat input.
Long focal length optics for deeper weld penetration (up to 600µ or more) and greater working distance without increasing laser output power.

High Speed Aluminum Industrial Laser Welder - 300W-1

LASER WELDING LW300AH Aluminum High Speed Laser Welding • Three times faster than conventional Nd:YAG laser welders • High power density • Small spot diameter • Deep, crack-free welds with minimal heat input • Long focal length Laser welding of aluminum alloys presents significant challenges for manufacturers of Lithium Ion battery cases, electronic packages, PC chassis and other products – particularly when high speed and deep weld penetration are critical objectives. Even with proper alloy selection, joint design and fit up, traditional pulsed Nd:YAG lasers are slow, and produce shallow penetration welds. Miyachi America Corporation’s novel approach couples MORE LASER POWER into a smaller fiber, thus achieving smaller spot diameters and higher power density needed to overcome the reflective characteristics of aluminum and achieve the absorption phase of the metal. Our proprietary high-brightness resonator design employs longer focal length optics which assures deeper weld penetration – up to 600µ or more – and allows a greater working distance without increasing laser output power. LW300AH, configured for HIGH SPEED ALUMINUM welding applications, is capable of seam weld speeds of up to 40mm per second; 3 TIMES FASTER than any other fiber delivered 300 watt Nd:YAG laser. LW300AH’s high-brightness design achieves significant increases in laser welding speed and deeper penetration in laser weldable aluminum alloys: deep penetration, crack-free welds are possible using this innovative laser design – with weld speeds up to 3 TIMES FASTER than conventional laser welding methods. TYPICAL APPLICATIONS Cross Section Together with the Real Time Power Feedback, Power Ramping and Pulse Shaping features of our A Series Nd:YAG lasers, LW300AH is the perfect solution for welding aluminum.
