The paper presents the results of mechanical tests to determine changes in the strength characteristics of the material of zirconium alloy E125 after local thermal exposure. Dependences of the strength characteristics of the material of the E125 alloy on the hardness are determined. The maximum and minimum values of strength in the zones of reflow and heat exposure have been determined. An assessment of the change in the geometric parameters and the hardness of the heat- affected spot from the modes of arc action and the conditions of subsequent cooling is carried out.
