Measuring of Residual Stress in TIG Welding of the 304 Stainless Steel by Ultrasonic Method
In this research, the effect of different welding parameters on residual stress and microstructure of the weld region, as well as the comparison of two methods of measuring residual stress using critical fracture longitudinal wave method and preformation method have been investigated. For this purpose, the taguchi DOE methodology is used as a statistical method to optimize four parameters of pu...

متن کاملEvaluation of Hoop Residual Stress Variations in the Thickness of Dissimilar Welded Pipes by Using the Lcr Ultrasonic Waves
Original scientific paper Stress measurement by using ultrasonic waves is based on acoustoelasticity law, i. e. the relation between stress and wave velocity in engineering materials. Longitudinal critically refracted (LCR) wave is a popular ultrasonic wave in the ultrasonic stress measurement application. The LCR wave is a bulk longitudinal wave that travels within an effective depth underneat...
متن کاملUltrasonic Characterization of Austenitic Stainless Steel in Thermal Variations
This work focuses on the ultrasonic characterization and hardness of Austenitic stainless steel in thermal variation. The sample which was heat treated at 1050 o C has the highest hardness value and plays a dominant role in dispersion of carbides. Shear wave velocity and hardness show similar trend in variation with temperature. The effect of volume expansion would be to decrease the elastic co...
متن کاملTemperature Dependence of Residual Stress in Tin Films on 316 Stainless Steel
The residual stresses in a TiN film deposited by a reactive ion coating process on a 316 stainless steel sheet were determined by the sin$ X-ray diffraction method, at temperatures from 15-800 “C. Using specially designed nickel clips, the coated strip was heated by the passage of a resistive current, in conjunction with a surround heater, and the temperature was measured by a Pt/Pt-lO%Rh therm...
