前有随着我国电子工业的发展,铝及铝合金的应用越来越广泛,焊件结构的几何形状日趋复杂,有时一个小小的焊件竟由数十个零件组成,焊件的精度要求也愈来愈高。目前多采用防锈铝(LF21)制造焊件,但是这种铝合金的强度和硬度低,刚性不好,容易引起焊件的变形,因此在某些构件中已经不能满足要求,而必须采用硬度和强度较高的
Before With the development of China’s electronics industry, the application of aluminum and aluminum alloys more widely, the geometry of the weldment structure is increasingly complex, and sometimes a small weld actually composed of dozens of parts, the precision requirements of the weldment Also higher and higher. At present, the use of anti-rust aluminum (LF21) to manufacture the weldment, but the strength and hardness of this aluminum alloy is low, rigidity is not good, easily lead to deformation of the weldment, so in some components can no longer meet the requirements, but must be hardness And higher intensity
