遵照伟大领袖毛主席“洋为中用”的教导,本期选登了三篇工艺方面的文章。其中“扩展成形”与“惯性焊接”工艺具有小设备、高效能的特点,适于各种批量的部件生产使用;“变质奥氏体形变处理”一文介绍了一种新的热处理工艺,这种工艺对提高汽车钢板弹簧的疲劳强度,从而增加其使用寿命具有一定的实用价值。这三种工艺是国外汽车制造中近期出现的新苗头,但就目前来看,也还未获得稳定的使用。今略以介绍,目的是引起有关同志的注意,在探讨新工艺时参考。
In accordance with the teachings of Chairman Mao, the great leader, “learning from foreign countries,” three articles on craftsmanship were selected in this issue. The “extended forming” and “inertial welding” process with small equipment, high performance characteristics, suitable for a variety of batch production and use of parts; “metamorphic deformation treatment,” a paper describes a new heat treatment process, this Technology to improve the car leaf spring fatigue strength, thereby increasing its useful life has some practical value. These three kinds of craft are the new signs that appear recently in the foreign car manufacture, but for the moment, have not obtained the stable use yet. This is a brief introduction, the purpose is to attract the attention of comrades in the discussion of new technology reference.
