The residual stress of welding is caused by the non-uniform temperature distribution of welding parts caused by welding, the thermal expansion and cold shrinkage of weld metal, etc., so the residual stress will inevitably be generated alon…

The deformation causes of precision and complex molds are often complex, but we can reduce and control the deformation of molds by mastering the deformation rules, analyzing the reasons for the deformation, and adopting different methods t…

In actual production, heat treatment deformation adds many difficulties to subsequent processes, especially mechanical processing, which affects production efficiency and leads to scrap due to excessive deformation, increasing costs. Defor…
