Abstract
Functional structure of a technological complex for hybrid (laser-microplasma) welding with application of a solid-state Nd:YAG laser, operating in a repetitively pulsed mode with wide range of energy and pulse shape, and integrated direct-action coaxial plasmatron is designed. Suggested algorithms of synchronizing operation of pulsed heat sources for study of joint action from positions of required welding properties achievement give the opportunity to obtain experimental results of laser-microplasma welding process with mild steel for automobile industry, aluminium alloy processing, and nanomaterials sintering.
Keywords: hybrid welding, microplasma arc, laser radiation, pulse, experimental facility, arc current, shape of penetration
