几种国产焊条的COD试验研究

An Experimental Study on COD of Several Electrodes Made in China

摘要: 本文对国产几种常用的焊条(结506,结507)用小试样(10×10×100mm³),多种方法(阻力曲线、声发射、扫描电镜)进行了COD试验研究,重点讨论了声发射法用于COD测试的可能性。

Abstract: In this paper,COD of several commonly used electrodes made in China(J506,J507)is experimentally studied by means of small specimen (10×10×100mm³)with various methods(Resistance Curve,A.E.,and SEM).Focus is laid on the discussion of the possibility of adopting A.E.method in COD measurement.
