Mathematical modeling of electron beam deflection for welding in narrow gap

In this paper the technology of an electron beam deflection directly in the weld joint during the welding process is considered. The technique of mathematical simulation of the electron beam deflection in the gap between the magnetic circuit tips has been worked out. Mathematical modeling of the equipment operation was carried out using the materials of EP517 steel and ARMCO iron. According to the mathematical model, the magnetic induction distribution in the gap is constructed. The model passed a successful verification by experimental measuring the magnetic induction in the gap. (paper)
