焊接技术已广泛地应用于国民经济的各个领域,无论是工业、农业、国防和科学事业的发展,都与焊接技术的推广和应用密切相关。焊接技术的发展促进和推动了科学技术的发展,而科学技术的迅猛发展反过来又对焊接技术提出更高、更苛刻的要求。为了完成日益繁多的焊接任务,近年来成功地研制和应用一些新的焊接工艺与方法。在电子管制造过程中采用的金属连接方法主要有钎焊、电阻焊、钨极惰性气体保护焊、冷压焊等。而电子束焊、等离子弧焊、激光焊和真空扩散焊等一些较新的焊接技术也部分地得到实际应用。在实际工作中如果能合理地选择焊接方法可以缩短研制周期和提高器件质量。因此,对于制管工艺人员和设计人员来讲。应该比较全面了解和掌握多种电子管焊接技术,以备实际工作中选用。为此,本刊从本期开始将陆续介绍电子管用的有关各种焊接技术资料,以供设计人员和工艺人员参考。
Welding technology has been widely used in all areas of the national economy, whether it is the development of industry, agriculture, national defense and science are closely related to the promotion and application of welding technology. The development of welding technology to promote and promote the development of science and technology, and the rapid development of science and technology and welding technology in turn put forward higher and more stringent requirements. In order to complete an increasingly wide range of welding tasks, in recent years successfully developed and applied some new welding processes and methods. In the tube manufacturing process used in the metal connection methods are brazing, resistance welding, tungsten inert gas welding, cold-pressed welding. Some of the newer welding technologies, such as electron beam welding, plasma arc welding, laser welding and vacuum diffusion welding, have also been partially realized. In practical work if you can choose a reasonable welding method can shorten the development cycle and improve the quality of the device. Therefore, for the pipe manufacturing process and design personnel speaking. Should be more fully understand and master a variety of tube welding technology, to prepare for practical work. To this end, this issue from the beginning of this issue will be introduced electron tube with a variety of welding technology information for designers and process staff reference.
