A Review on Welding Residual Stress Measurement by Hole Drilling Technique and its Importance
Year: 2018
Type: article
Abstract: 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.
