In-process detection of weld defects using laser-based ultrasound
Laser-based ultrasonic (LBU) measurement shows great promise for on-line monitoring of weld quality in tailor-welded blanks. Tailor-welded blanks are steel blanks made from plates of differing thickness and/or properties butt-welded together; they are used in automobile manufacturing to produce body, frame, and closure panels. LBU uses a pulsed laser to generate the ultrasound and a continuous ...
متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
متن کاملModeling and prediction of weld strength in ultrasonic metal welding process using artificial neural network and multiple regression method
In ultrasonic metal welding, two metal sheets are joined by the application of high frequency ultrasonic vibrations (20 kHz) under moderate pressure in which the vibrations are applied parallel to the interface between the sheets. The high frequency relative motion between the sheets forms a solid–state weld through progressive shearing and plastic deformation between surface asperities that di...
متن کاملWeld defect detection using a modified anisotropic diffusion model
This article proposes a new modified anisotropic diffusion scheme for automatic defect detection in radiographic films. The new diffusion method allows to enhance, to sharpen anomalies, and to smooth the background of the image. This new technique is based on the modification of the classical diffusion rule by using a nonlinear sigmoidal function. Experimental results are carried out on multipl...
متن کاملA Case Study on the Evaluation of Friction Stir Welds by Ultrasonic Inspection Technique
Friction stir welding (FSW) is an innovative process that has been successfully used in joining aluminum alloys, normally difficult to weld. Important advantages over fusion welding are better retention of baseline material properties, lower residual stresses and excellent mechanical properties. Defects that occur in FSW joints are due to improper tooling or setup. Non-destructive techniques us...
