What is Stress Relieving and Why We Need It WELDING

The temperature to which we heat a part for stress relieving must be below the materials transformation temperature.For ferritic steels,this transformation temperature is around 1350F [730C].For most steels,the stress relieving temperature will be around 1100-1200F [600 650C].Certain steels may require higher temperatures.US9499393B2 - Stress relief MEMS structure and package Stress relief structures and methods that can be applied to MEMS sensors requiring a hermetic seal and that can be simply manufactured are disclosed.The system includes a sensor having a first surface and a second surface,the second surface being disposed away from the first surface,the second surface also being disposed away from a package surface and located between the first surface and US9499393B2 - Stress relief MEMS structure and package Stress relief structures and methods that can be applied to MEMS sensors requiring a hermetic seal and that can be simply manufactured are disclosed.The system includes a sensor having a first surface and a second surface,the second surface being disposed away from the first surface,the second surface also being disposed away from a package surface and located between the first surface and
