The optimisation of laser welding process parameters of 7020 aluminium alloy

Abstract

В работе изучено влияние технологических параметров процесса лазерной сварки на геометрию сварного шва, включая грублину и ширину, а также влияние соотношения различных параметров, например, мощность лазерного пучка и скорость его движения.

Laser welding has been proven to be promising for the aerospace industry. Welds with high aspect ratio are produced with lower heat input compared with conventional welding is given, combining the trials with Nd:YAG laser and existing knowledge in the referred literature. In this work, we studied the effect of process parameters on weld profile geometry including penetration depth and width on top surfaces and interfaces as well as its quality at different process parameters such as Laser power and speed.
