Title: Anthony J Griffith: Innovator in Laser Welding Technology
Introduction
Anthony J Griffith is a notable inventor based in Bristol, GB. He has made significant contributions to the field of laser welding technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of welding processes, particularly in the aerospace industry.
Latest Patents
One of his latest patents is titled "Method and apparatus for laser welding with plasma suppression." This invention involves a laser welding apparatus where a laser beam is directed at a component to be welded. A plasma suppressor is strategically positioned to direct a jet of gas onto the component at an angle, flowing towards the laser beam impingement point. This innovative approach helps to improve the quality of the weld by minimizing plasma formation during the process.
Another significant patent by Griffith is related to "Drilling turbine blades." This invention addresses the challenge of creating small cooling holes, ranging from 0.25 to 0.9 mm in diameter, in cast hollow turbine blades. The method involves delivering successive pulses of laser energy to the blade's surface until complete penetration is achieved. By keeping the ceramic casting core in place during the drilling process, the laser beam is prevented from damaging the far wall of the cavity defined by the ceramic core. The core can then be removed using common leaching techniques.
