Throughout the year, OSA offers its members the opportunity to communicate directly with US senators and representatives. These meetings give the scientific community a voice in the halls of Congress-calling on elected officials to recognize the importance of science and technology, keep federal R&D funding levels consistent and sustainable, and support science, technology, engineering and math (STEM) education programs. OSA organizes all aspects of visits, from scheduling individual appointments to providing participants with detailed background information and talking points.

Design and Fabrication of Portable Weld Residual Stress Measuring Device using MBN Principle2020 •
Residual stress are stresses that remains in an engineering material, especially metallic materials, after the original applied load has been removed. Its measurement will help reveal areas in fabricated materials highly stressed. This paper presents a design of a portable residual stress measuring device based on the magnetic barkhausen noise principle. This was achieved by using two permanent magnets, a pickup coil, amplifier and an analogue to digital converter to create the hardware. The software was designed using LabVIEW 2019. After fabrication, measuring experiments on mild steel materials were conducted and the results obtained from using the device for measurement were compared to simulated values (Simufact.Weld 6.0) CAD software. Comparing its results with that obtained from Simulation showed an R 2 value of 77.47% with a strong correlation of 0.831and a P-value of 0.0071 which was less than the 0.05 alpha level taken. This device can be adopted in weld residual stress measurement by artisans and roadside welders for effective minimization of residual stress and failures associated with it.
