Description
греве контактирующих друг с другом алюмини и меди.heating of aluminum and copper in contact with each other.
На1несени покрыти способствует предохранению свариваемых поверхностей от окислени , обеспечивает стабильную величину электрического сопротивлени в контакте деталь-деталь и повышает стабильность по показател м прочности сварных соединений.The deposition of the coating helps to protect the surfaces being welded from oxidation, provides a stable amount of electrical resistance in the contact of the part-detail and improves the stability in terms of the strength of the welded joints.
Кроме того, введение никел в состав материала покрыти обеспечивает комплексное легирование сварочной точки, повышающее прочность сварных соединений.In addition, the introduction of nickel into the composition of the coating material provides a comprehensive alloying of the welding point, which increases the strength of welded joints.
Пример. Проводилась контактна точечна сварка листов из алюмини марки АД1 толщиной 2 мм, на соприкасающиес поверхности которых было нанесено покрытие никель + 30 вес. % меди. Толщина покрыти , наносимого химическим способом, составл ла 4-5 мкм. С целью получени сравнительных данных проводилась точечна сварка таких же листов, на соприкасающиес поверхности которых химическим способом наиосилось покрытие из чистого никел толщиной 4-5 мкм. Сравнение полученных результатов показало, что при одинаковой толщине покрыти дл образовани сварной точки в случае нанесени сплава никель + 30 вес. % меди требовалась на 15% меньща сила тока и на меньща длительность его протекани . Прочность сварных соединений, полученных после нанесени сплава никельмедь , была примерно равна прочности соединений , полученных после химического никелировани .Example. Contact spot welding was carried out on sheets of aluminum of the АД1 brand with a thickness of 2 mm, on the contacting surfaces of which nickel was coated + 30 wt. % copper. The thickness of the chemical applied coating was 4-5 µm. For the purpose of obtaining comparative data, spot welding of the same sheets was carried out, on the adjoining surfaces of which, chemically, a coating of pure nickel 4-5 microns thick was applied. A comparison of the results obtained showed that with the same thickness of the coating to form a weld point in the case of nickel alloy deposition + 30 wt. % copper was required at 15% less current and less duration of its occurrence. The strength of the welded joints obtained after deposition of the nickel-copper alloy was approximately equal to the strength of the joints obtained after chemical nickel plating.
Использование данного способа подготовки к контактной точечной сварке изделий из алюмини и его сплавов позволит уменьшить стоимость подготовки и снизить расход электроэнергии.Using this method of preparation for resistance spot welding of products from aluminum and its alloys will reduce the cost of preparation and reduce energy consumption.
