Study on temperature field in the process of induction heat treatment with current assisted weld double side method.

10 b) also gradually increases, and the thermal conductivity of the upper and lower surfaces of the weld seam is affected by the dual heat source, resulting in a decrease in temperature difference; The auxiliary current density shows a decreasing trend from the lower surface to the upper surface, and the auxiliary current density of the weld seam is significantly reduced compared to the auxiliary current density in the heat affected zone.
