METHOD FOR PRODUCTION OF SAFETY/RUPTURE DISCS |
| 摘要 |
A method for production of safety/rupture discs (1) comprises the steps providing a foil element (1a), selecting a wavelength for a laser beam of a pulse laser within a range of between 800 nanometers and 1800 nanometers, selecting a pulse repetition rate for the laser beam within a range of between 15 KHz and 800 KHz, selecting a pulse duration for the laser beam less than 10 nanosecond and ablating at least one non-through cut (2) in the foil element by directly applying said laser beam to the foil element to remove material from the foil element (1a) thereby obtaining a safety/rupture disc. |

1. A method for production of safety/rupture discs, comprising the steps of: providing a foil element;
selecting a wavelength for a laser beam of a pulse laser within a range of between 800 nanometers and 1800 nanometers; selecting a pulse repetition rate for the laser beam within a range of between 15 KHz and 800 KHz; selecting a pulse duration for the laser beam less than 10 nanosecond and ablating at least one non-through cut in the foil element by directly applying said laser beam to the foil element to remove material from the foil element thereby obtaining a safety/rupture disc.
