21. Residual stress in a T-butt joint weld : cylinder versus plane plate geometry
Sammanfattning : The welding process introduces residual stress originating from the heating, melting and cooling of the material. From the point of view of fatigue and stress corrosion cracking, the weld residual stress perpendicular to the weld axis is of particular interest. LÄS MER
22. Imaging and analysis methods for automated weld inspection
Sammanfattning : All welding processes can give rise to defects, which weakens the joint and can eventually lead to the failure of the welded structure. In order to inspect welds for detects, without affecting the usability of the product, non-destructive testing (NDT) is needed. LÄS MER
23. Life assessment from weld microstructures at high temperatures
Sammanfattning : Most pressure vessels in fossil power plant are designed forcreep. After operation of the order of the design lifetime thematerial may be degraded and further operation is limited.Methods which can prolong the lifetime and assess thecomponents is therefore demanded. LÄS MER
