以建立普通低合金钢系统为中心目标的钢铁产品革命,具有重大的经济意义和战略意义。普通低合金钢比碳素钢的使用价值不仅从数量上约可二顶三,且在质量、使用寿命和使用范围上亦较碳素钢大为优越。从焊接施工来说,也可大大减少焊接工作量。因此,这次钢铁产品革命是完全符合总路线精神的。由于焊接所涉及面极广,不可能一一加以叙述。现仅就其中几个普遍性问题加以讨论,使焊接技术能更快地适应钢种革命形势的要求。
It is of great economic and strategic significance to revolutionize steel products with the objective of establishing ordinary low-alloy steel systems. Ordinary low alloy steel than the use of carbon steel not only from the number of about two top three, and in quality, service life and scope of use than carbon steel is superior. From the welding construction, but also can greatly reduce the welding workload. Therefore, this revolution in steel products is entirely in line with the spirit of the general line. Due to the wide range of welding involved, it is impossible to describe one by one. Only a few of these general issues are discussed so that welding technology can more quickly adapt to the requirements of the revolutionary situation of steel.
