Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 The scientific basis and the methods of control process of metal penetration and welding formation during the pulse (pulse-periodic) TIG, microplasma and hybrid (laser microplasma) welding and pulsed-arc welding of fasteners through the optimization of the spatial and temporal parameters of pulsed sources of heat or on the surface of the base metal, or on the surface and deep into the live soft tissues to be welded or subjected to heat treatment have been created. Physical mechanisms to improve the quality of welded joints produced by such methods have been identified and the optimal spatial and temporal characteristics of the heat pulse and pulse-periodic action have been defined. The mathematical models and software for computer simulation of unsteady processes in the arc plasma and the weld metal and welded fixing elements of dissimilar materials have been developed. Tested specialized equipment for pulsed arc, HF microplasma and hybrid (laser-microplasma) welding, and welding and heat treatment of live soft tissues have been created. Evidence-based recommendations for the specified process of welding and treatment have been formulated.
