About this document
Post-Weld Heat Treatment of S690QL1 Steel by angga hermawansyah is a document available to read on EtoBox.
The article investigates the effects of Post-Weld Heat Treatment (PWHT) on S690QL1 high-strength steel welded joints, focusing on microstructure, mechanical properties, and residual stress. Various PWHT cycles were tested, revealing that while higher treatment temperatures reduce residual stress, they also degrade mechanical properties. The authors recommend using a specific PWHT cycle (max. 550 °C) that achieves significant stress reduction while maintaining acceptable mechanical performance.
