Plate bending fatigue properties of Mg-9%Al-1%Zn-2%Ca alloy joints prepared by friction stir welding
Plate bending fatigue tests were conducted for the Mg-9mass%Al-1mass%Zn-2mass%Ca alloy joints prepared by friction stir welding under two different conditions of stress ratio 0 and -1. The limit FSW was above 80% that base metal all test conditions. Fracture origin observed at thermo-mechanically affected zone (TMAZ) in joints. higher than inert gas (MIG) tungsten (TIG) fused (FZ) both MIG join...

Welds made with 304 austenitic stainless steel play an important role in high-pressure hydrogen storage systems. However, there are few investigations of the effect heat input on embrittlement (HE) tungsten inert gas (TIG) welded steel. In this study, HE TIG is investigated. It was found that increase welding input, ferrite content weld shows a tendency to first and then decrease. From perspect...
A new spectral processing technique designed for application in the on-line detection and classification of arc-welding defects is presented in this paper. A noninvasive fiber sensor embedded within a TIG torch collects the plasma radiation originated during the welding process. The spectral information is then processed in two consecutive stages. A compression algorithm is first applied to the...
The full-scale Sector Model Project, which was initiated in 1995 as one of the Large Seven ITER R&D Projects, completed all R&D activities planned in the ITER-EDA period with the joint effort of the ITER Joint Central Team (JCT), the Japanese, the Russian Federation (RF) and the United States (US) Home Teams. The fabrication of a full-scale 18 toroidal sector, which is composed of two 9 sectors...
The study focused on the standalone TIG and MIG welding combined effect, emphasizing microstructural properties strength of welded joint, especially heat-affected zone. literature revealed that both techniques their combination have full penetration in terms weld, HAZ for TIG-MIG has a larger width comparison with MIG. joints usually demonstrate ductile fracture compared or joints. However, it ...
Welding is a suitable and better process to manufacture complex objects for aerospace, naval, automotive structures. Service conditions complexity in load acting force the manufactures make joints between dissimilar materials. Thus, there need efficient welding techniques form sound an understanding of imperfections their effects. In this study attempt has been made joining feasibility aluminum...
