  title={Application of fractal theory in examination of resistance spot welding quality},
  author={Hou Zhan-feng and Wu Pei and Xue Jing and Han Jingyu},
Resistance spot welding is a technology applied extensively in mechanical manufacturing industry, non-destructive testing of resistance spot weld quality has been a hot research project in welding field. In this paper, spot welding tests were carried out and the welding spot surface images were acquired. Testing calculational formula of box-counted dimension were introduced. Calculational method about box-counted dimension was given and program about dimension and image processing based on… 
Optimization of resistance spot welding parameters for microalloyed steel sheets
Abstract The paper presents the results of resistance spot welding of hot-dip galvanized microalloyed steel sheets used in car body production. The spot welds were made with various welding currents
Probing weld quality monitoring in friction stir welding through characterization of signals by fractal theory
Providing solutions towards the improvisation of welding technologies is the recent trend in the Friction stir welding (FSW) process. We present a monitoring approach for ultimate tensile strength of
