the zinc coatings that are universally used forcorrosion protectionexists as liquid metal within and adjacent to the weld. It is believed that the combination of very highhardenabilityrequired to achieve the necessary microstructures for third-generation steels and the presence of some elements, such ...
According to the observation, there are major convection flow in the weld pool and very strong eddy current flows on the molten metal near the front edge of the weld pool at bottom. The liquid metal motions are not steady, and their patterns are very complicated. However, there is no ...
aThe difference is that the weld filler metal is not melted in the arc but in liquefied welding flux — the liquid slag – as a result of Joule resistance heating. 区别是焊接填充金属没有被熔化在弧,而是在液化焊剂-液体炉渣-由于焦耳电阻加热。[translate]...

The liquid zone contains the metal in fusion, whose temperature is the arithmetic mean of the vapor and fusion temperatures. The diameter D of this molten zone is supposed to be a cylindrical form, representing the weld width after processing. In this zone, it has been considered that the ...

When the slag–metal system, for example, SiO2-CaO-FeO slag–iron alloy, is in equilibrium state, the number of freedom for the system is 2. Therefore, if temperature and pressure are fixed, the number of freedom is equal to zero, which means that all of the composition of slag and ...
