Analysis of Spot Weld Joints by Ultrasonic Inspection, Fem and Residual Stress Measurements
The present work seeks to determine the parameters for approval, through ultrasonic techniques, of spot welded joints of low carbon steel sheets. For such experience the mechanical behavior of a spotwelded joint was characterized under fatigue, in load cycles ranging from zero to 14 kN, on sheets of 1.5 mm thickness, joined by three spot welds of 7.5 mm of medium diameter, being the distance am...
متن کاملUltimate Strength and Failure Mechanism of Resistance Spot Weld Subjected to Tensile, Shear, or Combined Tensile/Shear Loads
Strength tests were performed to reveal the failure mechanisms of spot weld in lap-shear and cross tension test samples. It is shown the while the lap-shear (cross tension) sample is subjected to shear (normal) load at the structural level the failure mechanism at the spot weld is tensile (shear) mode at the materials level. Based on the observed failure mechanism, stress distribution is assume...
متن کاملSpot Weld Analysis With 2D Ultrasonic Arrays
This paper describes a threefold method of testing the performance of an array-based ultrasonic tool for nondestructive testing of spot welds. The tool is described in its capabilities, use, and advantages over existing counterparts. Performance testing for and the results from carrying out the testing are described. The three performance testing methods include 1) the use of calibrated samples...
متن کاملPattern of Residual Stress in Rail by FEM Analysis and Strain Gage Sectioning Technique
Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...
