Изобретение относитс к электросварке , преимущественно к аргонодуго вой сварке неплав щимс электродом алюминиевых сплавов на асимметричном разнопол рном токе, и может быть использовано во всех отрасл х народного хоз йства дл сварки конструкций из алюминиевых сплавов.The invention relates to electric welding, mainly to argon-arc welding by non-consumable electrode of aluminum alloys on an asymmetric current of different currents, and can be used in all sectors of the national economy for welding structures made of aluminum alloys.
Целью изобретени вл етс получение качественных сварных соединений путем создани оптимальных режимов сварки, а также повьш1ение стойкости вольфрама.The aim of the invention is to obtain high-quality welded joints by creating optimal welding conditions, as well as increasing the resistance of tungsten.
На чертеже представлено изменение токов пр мой и обратной пол }знос тей в течение всего цикла сварки.The drawing shows the change in forward and reverse field currents during the entire welding cycle.
После зажигани дуги (см.черт.) ток пр мой I|j пол рности достигает св.оего рабочего значени за врем t , а ток обратной пол рности 1, - за врем t,, при этом благодар тому, что врем нарастани тока пр мой пол рности больше, чем на обратной , рабочий ток пр мой пол рносAfter ignition of the arc (see sketch.), The direct current I | j of polarity reaches its operating value during time t, and the current of reverse polarity 1, during time t, due to the fact that the current rise time is my polarity is greater than the reverse, the operating current is right

ти, как обеспечивающий расплавление кромок воздействует -на уже очищенную их поверхность рабочим током обратной пол рности. От момента t 5 до t производ т сварку на установленном режиме. С момента t, после окончани швй производ т заварку кратера, при этом благодар тому, что рабочий ток пр мой пол рности 10 снижают за врем t4 меньшее, чем t, - врем снижени тока обратной пол рности, происходит качественна заварка кратера без образовани черного налета и рыхлот, 15 Примеры осуществлени способа приведены в таблице.As it provides melting of the edges, it acts on the already cleaned surface of the working current of reverse polarity. From the moment t 5 to t, the welding is performed in the set mode. From the moment t, after the end of the seam, the crater is welded, while due to the fact that the operating current of direct polarity 10 is reduced during time t4 less than t, the time of reverse polarity current reduction, high-quality crater welding takes place without black bloom and loosening, 15 Examples of the method implementation are given in the table.
Использование способа позвол ет повысить качество сварных соединений из алюминиевых сплавов особенно в начале их выполнени и при заварке кратера, а также повысить стойкость электрода и производительность процесса .The use of the method allows to improve the quality of welded joints from aluminum alloys, especially at the beginning of their implementation and when brewing the crater, as well as to increase the durability of the electrode and the efficiency of the process.
