Hot Deformability of Weld Metal

Journal of the Japan Welding Society, 1973
In order to study the mechanism of hot cracking in aluminum alloys, the characteristics of brittle range existing behind the molten pool are investigated experimentally by using special tension executed soon after the welding. As to the characteristics of brittle range in weld metal, length, temperature range and minimum quantity of deformation ...

Statistical Treatment of Welding Deformation(Report 1). Statistical Property of Welding Deformation in Fillet Welding Tee Joint Flange.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1999
At present, the parameters to control the welding deformation of the basic welding joints have been made almost clear and, to some extent, they can be estimated from the welding conditions. However, the welding deformation is expected to depend on welding operators because it is affected by the welding conditions such as welding heat input, leg length,

Prediction of the welding distortion of large steel structure with mechanical restraint using equivalent load methods

International Journal of Naval Architecture and Ocean Engineering, 2017
The design dimension may not be satisfactory at the final stage due to the welding during the assembly stage, leading to cutting or adding the components in large structure constructions.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
