Abstract
Results of computer modelling of the process of hybrid welding of Al-Mg system aluminium alloys up to 10 mm thick by using a dynamic model are considered. Examples of computation of the welding process parameters and their experimental validation are given. The developed technological laser-arc system for implementation of the hybrid welding process is described.
 
 
Keywords: laser and laser-arc welding, aluminium-magnesium alloys, process modelling, computations, geometric characteristics of the weld, thermal cycles, distribution of alloying elements, package of equipment, monitoring of the welding process
