Weldability of Inconel625 alloy:
1.Inconel625 alloy, the high content of Cr and Mo provides the alloy with better resistance to pitting and fission corrosion, even at high temperatures, still has anti-corrosion characteristics;
2.Inconel625 alloy, the content of Cr is as high as 22.2%, which improves the strength of the alloy. A certain amount of Mo also improves the creep strength of the alloy. At the same time, a small amount of Al and Ti reduces the age hardening effect of the alloy to a lower level. To improve the weldability of the alloy;
3.Inconel 625 alloy, due to the presence of a certain amount of S and P, the segregation coefficients of S and P are the largest among various elements. At the same time, S and P can also form a variety of low-melting compounds or eutectics in the steel, and, Because Ni is an element that strongly stabilizes the γ phase, it reduces the solubility of S, increases the possibility of low-melting eutectic formation, and is conducive to the formation of thermal cracks;
4.Inconel 625 alloy has a relatively large linear expansion coefficient, but its thermal conductivity is small, which causes the alloy to be heated and cooled unevenly, so that the plastic strain occurring between the crystals at the high temperature stage is also larger. The larger the plastic strain, the easier it is to crack. ;
5.Inconel 625 alloy is a nickel-based alloy with a small solid-liquid temperature interval and a fast solidification rate, which can easily cause oxygen or water vapor in the liquid molten pool to overflow in time to form pores;
