About this document
Delayed Hydrogen Cracking in SAW Joints by afab is a document available to read on EtoBox.
The document summarizes research on assessing delayed hydrogen-assisted cracking in thick-walled submerged arc welding joints for offshore applications. A 50mm thick steel mock-up component with over 20 welding passes was constructed to simulate residual stresses in large offshore structures. Ultrasonic testing was performed up to 48 hours after welding to identify potential cracking, and residual stresses were measured via X-ray diffraction. No cracking was found, confirming the material
