Abstract
Способ сварки трехфазной дугой, включающий плавление металла дугой, горящей между двумя неплавящимися электродами и изделием, с подачей в образовавшуюся сварочную ванну присадочной проволоки, подключенной к средней фазе источника питания трехфазной дуги, отличающийся тем, что в момент окончания процесса сварки в зону сварки вносится подключенный к фазе изделия вольфрамовый катетер на расстояние от оси горелки 8-10 мм, что обеспечивает уменьшение объема расплавленного металла и нейтрализацию воздействия силовой составляющей трехфазной дуги на металл сварочной ванны, что обеспечивает уменьшение геометрических размеров усадочной раковины, за счет чего повышается качество сварного соединения. A method of welding with a three-phase arc, including melting the metal by an arc burning between two non-consumable electrodes and a workpiece, with filler wire supplied to the resulting weld pool connected to the middle phase of a three-phase arc power source, characterized in that a connected wire is introduced into the welding zone at the end of the welding process to the product phase, a tungsten catheter at a distance from the axis of the burner is 8-10 mm, which ensures a decrease in the volume of molten metal and the neutralization of the impact of the three-phase power component arc on the metal of the weld pool, which reduces the geometric dimensions of the shrink shell, thereby improving the quality of the welded joint.
