Steel castings are the parts formed by cooling and solidification after pouring steel into a specific mold after melting. Steel castings are divided into ordinary carbon steel, low alloy steel, high alloy steel and so on. There are many problems in the welding process of large steel castings.
1. The lack of welding of steel castings is related to which factors.
The role of the element is closely related to its existing form or form in steel, whether it forms a compound or enters the solid solution, the role is different, so when talking about the role, we must explain its existence form. Different steels, after different heat treatment, make the existing form of alloy elements change. At this time, the role of alloy elements will also change. If you want to use alloy elements very alive, it is still very difficult. Generally speaking, it is not right to say that a certain element has a certain effect. The environment has changed, and its role has changed, and even have a bad effect.
two。. Factors related to the occurrence of welding cracks in steel castings.
Whether the steel castings are low carbon, medium carbon, high carbon, repair welding, surfacing welding, wall thickness uniformity, welding current and other factors will affect the welding crack.
