Abstract

The use of a combination of 2 or 3 Nd:YAG lasers having each an output power of 3 or 4 kW is presented in the case of heavy section welding. We discuss the main difficulties that are occurring for these conditions. The strategy leading to the welding of sample thickness up to 60 mm is presented.
