... operation, it is necessary to understand the effect of excessive loading, such as an earthquake, on the residual stress. Three-dimensional finite element analyses were performed using three-dimensional model for a 250A pipe butt weld of low-carbon stainless steel of type 316L. The welding simulation method...

... application ( 3 ). To ensure the absence of subsurface fusion problems, ultrasonic testing methods have been developed. Although time-of-flight diffraction (TOFD) methods have been used effectively for volumetric examination of HDPE butt welds, another promising technology is ultrasonic phased array...

.... Then a probabilistic design methodology based on the ASME B&PV Code and focused on straight pipes with butt-welds is presented. The method ensures an acceptable reliability level for piping by keeping the failure probability within some upper threshold and accounting for the uncertainties of the design variables...

...Katsumasa Miyazaki; Masanori Numata; Koichi Saito; Masahito Mochizuki The fixed conditions of butt welds between straight pipe and the valves or pump in an actual piping system are different from those of straight pipes. However, the effect of the fixed condition on the residual stress...

...Xu Zeliang Welding groove geometry is one of the factors determining the structure’s weld-induced deformation. There are three types of welding groove geometry available for a full-welded ball valve. Multipass butt-welded plate experiments and finite element analysis were applied to determine which...

... in place in contact with the elements of the base plate, and the interaction is made to be a function of time. This gave several flexibilities in modeling the welding process. Hence, the technique is then used to analyze simple fillet welding of a plate and circumferential butt welding of a pipe...
