Development of welding technology for responsible products made of aluminium alloys based on computer modeling of weldability indicators

The technology of TIG-welding of responsible products from aluminum-magnesium alloy AMg6 has been developed. As indicators of weldability, determining the quality of the welded joint, the normalized dimensions of the weld and the resistance of the welded structure against the formation of crystallization hot cracks were used. To take into account the geometric features of the design, the trajectory of the weld, welding conditions, thermophysical and mechanical properties of the material used, computer simulation tools were used.
