A study for evaluating the weld joint strength reduction factor (WSRF) due to creep was conducted for alloy 740H-P92 dissimilar metal weld joint to be used advanced ultra-supercritical fossil power plants. To this end, a series of the creep rupture tests were carried out for P92 and alloy ...
In addition to this creep rupture curve for Mod.9Cr–1Mo steel weld joints, a provisional weld joint strength reduction factor (WJSRF) for Mod.9Cr–1Mo steel has also been proposed to develop the rules that limit primary stress in the JSME FRs code. Many studies have been carried out ...
The welding strength is a very essential factor to achieve the quality of welded joints. In the present concept, the two dissimilar alloys such as Inconel 625 and Al 7068 can be welded. The axial force, the spindle, and traverse speed were utilized as key factors. These key factors have ...
Review of weld angles on butt weld joint strength Good welding of pipe is crucial as bad welding can lead to cracks and failures. One of the parameter that affects the quality of weld is the bevel angle for single V butt joint weld. This paper aims to analyse the effect of ... KK Di...
To evaluate the welding fabrication technology in the TBM, one case of TIG welding conditions was selected based on the previous work by Yoon et al. (2013), and a single pass with one side weld procedure through a thickness in TIG weld was carried out using ARAA, Batch 2 (F206). The...

The aim of this study was to determine the typical incidence of micronuclei (MNi) in the peripheral blood lymphocytes of healthy middle-aged Koreans using the cytokinesis-block micronucleus cytome (CBMN-Cyt) assay. Non-smoking, low-risk alcohol-drinking healthy Korean men and women aged 30 to ...
strengthening is relatively insignificant. Although the grain refinement in the FQZ means that the grain boundary strengthening is∼2 times larger, the loss in strength arising from the reduction in the precipitation strengthening (a quarter that for the BM) means that overall it is significantly ...
‘No-weld’ happens when thelaser beam energyapplied to the material is not high enough to create fusion for a short segment or the entire length of the weld seam. No-weld is normally considered as aweld defectdue to the significant reduction of the weldstrength. When a short segment of ...
Weld strength is an important criterion for assessing weld quality. The welded joint strength is measured either as breaking load (N) of joint [2,4,11,111,121,122] or as weld strength per unit length of the weld (N/m) [19,34,62,74,83,91] or as shear or tensile strength of the...
