摘要
Preparation of a hollow space (16) in a workpiece (10) especially a fuel spray nozzle in which an open bore is produced by laser radiation. The equipment includes a protective element (22). Energy from laser radiation is decreased on passing thru open region (20), material is removed from it and deposited on the wall, which is subjected to wet chemical treatment to remove deposited material selectively. The protective element (sic) contains Mo or W, which can be removed selectively relative to Fe and steel by an alkaline solution of oxidizing agent.
