Stresstech Bulletin 15: Residual Stress in Welding
Modern industry has many requirements like cost efficiency, durability, lightness of manufactured parts and eco-friendliness to name a few. With these requirements in mind it’s crucial to have deep understanding of the manufacturing process and how it affects the finished part. Residual stress is one physical property that is becoming more crucial as the requirements and quality of manufacturing process grow.

Stresstech Bulletin 13: Types of Residual Stresses
Residual stresses are spontaneously in equilibrium as tensile residual stresses (detrimental) and compressive residual stresses (beneficial). For example, a surface formed in tensile stresses will comprise compressive residual stresses, and a surface formed in compressive stresses will contain tensile residual stresses.
