Technology Innovation for the Manual Laser Cladding of High-Alloy Tool Steels

This paper presents the development and successful application of an inductive preheating system running simultaneously with the manual laser cladding process in order to enable the repair of high-alloy tool steels having a highly limited weldability. In this study, the design and optimization of a...
