Tungsten is a very hard metal with great tensile strength and an extremely high melting point. It is often alloyed with other metals but in its purest form, it is commonly used in electronics applications – for example as interconnect material in integrator circuits, electron emitters and light bulb filaments.
Laser: SPI 200W water cooled Fiber Laser
Machining head: Laser Mechanisms, Finekerf
Focal length: 50 mm, X2 beam expander
Process gas: Argon 0.8 MPa
A series of rectangular slots were made at various laser parameters. Speeds up to 6 m/min were made using oxygen, argon and nitrogen as assist gases.
Using oxygen as an assist gas, a significant Heat Affected Zone (HAZ) was observed.
When nitrogen or argon were used as an assist gas, cut speeds were slower but much cleaner with far less heat affected zone. Cut width was 25 microns.
Clean cuts can be made on Tungsten using argon assist gas at high speed using our redPOWER QUBE CW Fiber Laser
