铝及铝合金以质轻、美观、耐蚀、高强度等优异的性能得到了各行业的重视,获得了越来越广泛的应用。铝制构件大量应用中出现的极为重要的问题,是构件的连接、维修方法与工艺。目前通常采用的连接方法有铆接、焊接与粘接等,这些连接方法各有千秋。因此,要根据产品构件的情况适当选择。下面就将铝钎焊工艺在铝及铝合金枪件维修中的应用介绍如下。一、铝钎焊的主要优点1.由于钎焊温度低于母材的熔点,所以,构件不易变形或变形很小。又因母材不熔化,所以金相组织不发生液相变化,不易产生过烧及过热组
Aluminum and aluminum alloy with light weight, beautiful, corrosion resistance, high strength and other excellent performance has been the industry’s attention, access to more and more widely used. The most important issue that arises from the large number of applications of aluminum components is the connection and maintenance of components and processes. At present, commonly used methods of connection are riveting, welding and bonding, etc., these methods have their advantages and disadvantages. Therefore, according to the situation of the product components appropriate choice. The following will be aluminum brazing process in the aluminum and aluminum alloy gun repair applications are described below. First, the main advantages of aluminum brazing 1. As the brazing temperature is lower than the melting point of the base metal, so the component is not easy to deformation or deformation is small. And because the base metal is not melted, so the microstructure does not change the liquid phase, not prone to over-burning and overheating group
