Abstract

This paper explores Residual Stress (RS) measurement in two robotically welded, S275 plates using Phased Array Ultrasonics for Residual Stress Measurement (PAURS) and Neutron Diffraction (ND), with the Incremental Hole Drilling (IHD) method employed for validation. Pogo ultrasonic simulation was used to model the Longitudinal Critically Refracted (LCR) wave and design the ultrasonic setup. Ultrasonic arrays operating at 5 MHz (8 elements) measured RS at a depth of ∼1.25 mm. Results show qualitative agreement among PAURS, ND, and IHD, with RS symmetrically distributed on both sides of the plates, validating the effectiveness of phased array probes for qualitative measurement. However, discrepancies in precise numerical values were observed across methods. As PAURS is a novel technique for welded samples, the paper highlights areas for improvement to enhance its quantitative measurement capabilities.

用相控阵超声分析机器人焊接板的残余应力，并通过中子衍射和钻孔方法验证

本文探讨了用相控阵超声残余应力测量（PAURS）和中子衍射（ND）测量两个机器人焊接的S275板的残余应力（RS），并采用增量钻孔（IHD）方法进行验证。采用Pogo超声模拟技术对纵向临界折射波进行了模拟，并设计了超声装置。工作频率为5 MHz（8个元件）的超声波阵列在深度约1.25 mm处测量RS。结果表明，PAURS、ND和IHD之间的定性一致，RS对称分布在板的两侧，验证了相控阵探头进行定性测量的有效性。然而，不同方法的精确数值存在差异。由于PAURS是一种新型的焊接样品定量测量技术，本文强调了需要改进的地方，以提高其定量测量能力。

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
