Description

Известны способы аргоно-дуговой сварки титана без присадочного металла, при которых сварной шов образуетс  за счет расплавленного металла изделий.There are known methods for argon-arc welding of titanium without a filler metal, in which a weld is formed due to molten metal products.

При сварке титана с алюминием и его сплавами известные способы сварки не обеспечивают необходимое качество сварного соединени .When welding titanium with aluminum and its alloys, the known welding methods do not provide the required quality of the welded joint.

Дл  устранени  указанного недостатка предлагаетс  при сварке титана с алюминием и его сплавами смещать сварочную дугу от свариваемого шва в сторону титана и до расплавлен 1  доводить только алюминшьTo eliminate this drawback, it is proposed, when welding titanium with aluminum and its alloys, to displace the welding arc from the weld seam towards the titanium and melt it 1 to bring only aluminum

Дл  выполнени  сварки используетс  горелка дл  аргоно-дуговой сварки с неплав гцимс  (вольфрамовым) электродом, снабженна  насадкой дл  подачн аргона на остывающий сваренный щов дл  защиты нагретого металла от взаимодействи  с воздухом. Нижн   поверхность шва также должна иметь газовую защиту. Рекомендуетс  применение медной или стальной подкладки с канавкой дл  формировани  нижней поверхности щва.For welding, an argon-arc welding torch with a non-melting (tungsten) electrode is used, equipped with a nozzle for supplying argon to cooling welded fittings to protect the heated metal from interaction with air. The bottom surface of the seam should also have gas protection. It is recommended to use a copper or steel lining with a groove to form the bottom surface of the joint.

Образование сварного шва происходит в результате диффузии расплавленного алюмини  в нагретый, но не расплавленный титан. Расплавление титана при сварке недопустимо, так как это приводит к образованию интерметаллических соединений, делающих щов хрупким.Weld formation occurs as a result of diffusion of molten aluminum into heated, but not molten titanium. Melting of titanium during welding is unacceptable, since this leads to the formation of intermetallic compounds, which make the shchi brittle.

При сварке рекомендуетс  использовать посто нный ток обратной пол рности (плюс на электроде). Зазоры свариваемых кромок не должны превышать 0,2-0,3 мм. Перед сваркой кромки очищаютс  травлением или другим известным методом.When welding, it is recommended to use direct current of reverse polarity (plus on the electrode). The gaps of the edges to be welded should not exceed 0.2-0.3 mm. Before welding, the edges are cleaned by etching or another known method.

Сварные соединени , выполненные предлагаемым способом, имеют прочность, не ниже прочности целого алюмини , и достаточно хорошую пластичность.Welded joints made by the proposed method have strength not lower than the strength of whole aluminum, and rather good ductility.

Предмет изобретени Subject invention

Способ аргоно-дуговой сварки титана с алюминием и их сплавов без присадочиого металла, отличающийс  тем, что, с целью повышени  прочности сварного соединени , сварочную дугу при сварке смещают от шва в сторону титана и до расплавлени  довод т только алюминий.The method of argon-arc welding of titanium with aluminum and their alloys without an additive metal, characterized in that, in order to increase the strength of the welded joint, the welding arc during welding is shifted from the weld to the side of titanium and only aluminum is brought to the melt.
