众所周知,影响铝及铝合金焊接质量的因素,比起碳钢及不锈钢,要复杂得多;除与焊前清理、焊接参数、焊丝化学成分、保护气体纯度、焊接工艺装置等因素有关外,还与接头型式及尺寸的合理选择有关。随着科学技术及四化建设的发展,铝制品的焊接生产量与日俱增。铝制品已广泛地应用于导弹壳体、飞机油箱、鱼雷外壳、电器设备、化工容器以及日常生活上所用的窗框、水箱等。
As we all know, the factors that affect the welding quality of aluminum and aluminum alloy are much more complex than those of carbon steel and stainless steel. In addition to the factors of cleaning before welding, welding parameters, chemical composition of welding wire, purity of protective gas and welding process equipment, With the connector type and size of a reasonable choice. With the development of science and technology and the four modernizations, the welding production of aluminum products is increasing day by day. Aluminum products have been widely used in missile housings, aircraft fuel tanks, torpedo housings, electrical equipment, chemical containers and window frames, water tanks and the like used in daily life.
