Welding is also the last process after the assembly of the product.

The welding process of thick-walled multi-layer welded ball valves involves repeated heating and cooling of the metal material, leading to inhomogeneous and inferior microstructure of the weld joint, high residual stress, and even welding defects. Welding is also the last process after the assembly of the product. The valve cavity contains non-metallic sealing materials such as rubber and polytetrafluoroethylene plastic, which cannot be subjected to post-weld heat treatment.

Welding ball valve Mn can also improve the properties, morphology, and distribution of sulfides. Therefore, in order to prevent the formation of crystallization cracks, there are certain requirements for the M/S value in the weld metal. How large the M/S value is to prevent crystallization cracks is also related to the carbon content. The higher the C content, the higher the M/S value required.
