The article presents a method for calculating the parameters of weldable edges during high-frequency welding
of pipe billets made from ferromagnetic material (low-carbon and low-alloy steels). It examines the features of current
distribution under the influence of the skin effect, proximity effect, and magnetic circuits. An approach is proposed to
account for the loss of magnetic properties in the heated zone, along with a correction coefficient for power and resistance
of ferromagnetic edges compared to non-magnetic ones. Calculation dependencies and graphs are provided to optimize
inductor parameters and welding regimes
