Abstract
The effect of conditions of argon-arc tungsten-electrode treatment of steels on the thermal cycle parameters is investigated. It is shown that to avoid incipient melting at an increase in amperage, it is necessary to raise the rate of treatment, increase the arc length to 7-15 mm and impart transverse oscillations to the arc. The treatment conditions allow the temperature of a short-time heating, duration of metal dwelling in a heated state and cooling rate to be controlled.
Keywords: arc treatment, high-strength steel, thermocouple, thermal cycle, heating temperature, cooling rate, austenization, transformation, structure, hardness, microhardness, hardening
