Abstract
A method is described for the separation of metal articles from surplus metal by the use of a laser. The articles may be cast or wrought. Several examples are given of gas turbine engine components being separated from a gating system by the use of a YAG laser. Benefits include lack of heat generation and, therefore, little or no distortion in the article.
