随着中国高速铁路的快速发展,铝合金焊接技术也在飞速发展,铝合金焊接在轨道客车的生产制造过程中也得到了广泛的应用。由于铝合金其材料本身的特殊性,也给焊接操作者带来了很大的难度,要想生产制造质量高、安全性强的轨道客车车体就需要掌握好铝合金焊接技术,并且掌握铝合金本身的基本特性,包括其焊接特点、焊接材料、焊接方法和焊接设备,掌握这些的最根本目的是避免在焊接过程中出现焊接缺陷。本文就已轨道客车为例,探讨铝合金焊接容易产生的缺陷及其预防措施。
With the rapid development of China’s high-speed railway, the aluminum alloy welding technology is also developing rapidly. Aluminum alloy welding has also been widely used in the manufacturing process of rail passenger cars. Due to the special nature of the aluminum alloy material itself, but also to the welding operator has brought great difficulty, in order to produce high quality and safety of rail passenger car body you need to master the aluminum welding technology, and grasp the aluminum The basic characteristics of the alloy itself, including its welding characteristics, welding materials, welding methods and welding equipment, the most fundamental purpose of mastering these is to avoid welding defects during the welding process. This article has track passenger cars as an example to discuss the defects of aluminum alloy welding and preventive measures.
