“…The distribution of longitudinal and transverse residual stresses,Figure 6(c & d),agrees with the results reported byKim et al (2009) who employed finite element simulation and neutron diffraction measurements for a V-butt steel. Also consistent trend can be found for the distribution of longitudinal residual stresses with the study (using experimentally validated FEA) carried out byVenkata et al (2014).…”

“…Meanwhile, maximum longitudinal tensile RS occurs near the interface of the weld and the HAZ (at about ±10 mm from the weld centerline). Similar results were reported by Kim et al [13]. They joined 9Cr-1 Mo steel plates using GTAW and measured RS with a neutron diffraction method.…”

This paper presents an experimental study that examines variations of Charpy impact energy of a welded steel plate, depending upon the welding method and the method for obtaining the Charpy specimens. Flux cored arc welding (FCAW) and Gas tungsten arc welding (GTAW) were employed to weld an SA516 Gr. 70 steel plate. The methods of wire cutting and water-jet cutting were adopted to take samples from the welded plate. The samples were machined according to the recommendations of ASTM SEC. II SA370, in order to fit the specimen dimension that the Charpy impact test requires. An X-ray diffraction (XRD) method was used to measure the as-weld residual stress and its redistribution after the samples were cut. The Charpy impact energy of specimens was considerably dependent on the cutting methods and locations in the welded plate where the specimens were taken. The specimens that were cut by water jet followed by FCAW have the greatest resistance-to-fracture (Charpy impact energy). Regardless of which welding method was used, redistributed transverse residual stress becomes compressive when the specimens are prepared using water-jet cutting. Meanwhile, redistributed transverse residual stress becomes tensile when the specimens are prepared using wire cutting.

Welding residual stress is considered as one of the most responsible factors by the experts for premature failure of the in-service welded structures. Between tensile residual stress and compressive residual stress, while the former type is found to have detrimental effect on the welded part, compressive stress may adhere to some benefits in many cases. It is, therefore, very important to evaluate the welding residual stress in a welded component properly so that suitable measures can be adopted to get the optimized service life of the fabricated structure. The measurement techniques of welding residual stress have been classified into different categories, significantly in destructive and non-destructive in nature. The hole drilling technique is one of the destructive methodologies to measure the welding residual stress using strain gauges which is standardized by ASTM E-837 and frequently used in the applied field. In this review paper, an effort has been given to understand the fundamentals of the hole drilling method based on extensive literatures' study which reflects the chronological developments of this technique in the field of stress measurement. This paper, further, describes the influence of different operational parameters associated with the hole drilling technique on the outcome of the process.
