This paper describes the absorption of 'laser light' by a workpiece and shows that the physical, chemical and thermal changes that result, can be controlled, to cause either drilling or welding of the workpiece. The subject is treated from a practical engineering/applications viewpoint and includes case studies of established industrial applications. The unique features of laser processing are highlighted and where appropriate, comparisons are made with other industrial processes.
