An abrasive article having an apertured coated abrasive member, filter media, and an attachment interface member is formed by an ultrasonic welding process.
Our calculations show that the Bessel-Gauss beam can be produced in the focused plane of the ring apertured Gaussian beam, this method is efficient and simple.
