Study of laws of electromagnetic fluxes during induction surfacing powder layer

Abstract

It is shown that the induction melting contributes portion of the tolerated electromagnetic power flow, which is associated with the appearance of the induction current in the steel-based powder layer. For parameters optimization of the magnetic flux it is suggested the use of the Call-energy functional, containing, besides the force characteristics of the electromagnetic-field strength, and the magnetic vector potential. The induced electromagnetic field produced by the electric current refers to the complex type of vector fields-potential field and vortex field. It has been shown that induction welding powder layer refers to a system with concentrated parameters, in which acts skin effect, due to zone size. According to this research, schemes and the system of equations determining the pattern of the control of electromagnetic flux during induction surfacing powder bed and the possibility of optimizing the technological parameters of the process are described.
