🧲 ASTM E1444 / ASME V (Circular Magnetization Current 30-45A per mm of Diameter)

MPI Head Shot Amperage Calculator

Calculate circular magnetization direct contact head shot electrical current (Amps AC / HWDC / FWDC) for aerospace and structural ferromagnetic steel components under ASTM E1444 & ASME Section V: calculate required shot amperage (30 to 45 Amperes per millimeter of outside diameter / 750 to 1,000 A/inch), prevent arcing burn, and NDT inspection profits.
