Abstract: Four basic electrodes were designed by the method of transition alloying elements
through coating. The influence of coating alloying elements on microstructure and properties of
basic electrode welded joints were studied by using welding test, metallurgical analysis,
mechanical property testing and fracture scanning tests. The results showed that with the
increase of alloying elements, the changes of four kinds of weld microstructure is small and
mainly composed of tempered sorbite and lath martensite, and accompanied by a small amount
of residual austenite and quadratic precipitated phase, but the microstructure gradually changed
from lath to thin strips, and staggered density increases. What's more, the strength of four
welded joints has a little changed, but the impact of toughness has a greatly improved and the
fracture dimples became many and deep. Last, the effect of coating alloying elements on welds
microstructure and properties is a complementary and mutual restraint process, and the content
of alloying element in No.3 electrode makes the basic electrode weld strength and toughness to
achieve a better matched.
