1.概况过去国产不锈钢电焊条多是低碳型的,如A102,A132等.随着化工、石油化工、核电等行业发展.材料抗腐蚀性要求提高,超低碳、特种不锈钢的生产和应用日益增加,国内开始生产A002、A022、A062、A042等.但是有的焊接性差,耐腐蚀性不稳定,国产焊条在品种和质量方面远远不能满足化工、石油化工、核电等行业设备制造的要求,因此,经常不得不大量进口.80年代后期,这个矛盾更加突出,
1. Overview In the past, mostly made of stainless steel welding electrodes are low-carbon type, such as A102, A132, etc. With the chemical, petrochemical, nuclear power and other industries development. Materials corrosion resistance requirements, ultra-low carbon, special stainless steel production and application Increasing, the domestic production of A002, A022, A062, A042, etc. However, some poor weldability, corrosion resistance is not stable, the domestic varieties and quality of the electrode is far from meeting the chemical, petrochemical, nuclear power equipment manufacturing industry requirements , Therefore, often have to import a large number of 80. In the late 1980s, this contradiction is even more prominent,
