    • Automated thresholding in radiographic image for welded joints 

      Haniza, Yazid; Hamzah, Arof, Dr.; Hafizal, Yazid (Taylor & Francis, 2012)
      Automated detection of welding defects in radiographic images becomes non-trivial when uneven illumination, contrast and noise are present. In this paper, a new surface thresholding method is introduced to detect defects ...
    • Circular discontinuities detection in welded joints using Circular Hough Transform 

      Hafizal, Yazid; Haniza, Yazid; Mohd Harun; Shukri Mohd; A. Aziz, Mohamed; Mohamed Rizon, Mohamed Juhari; Shaharudin, Sayutia (Elsevier B.V., 2007)
      Conventional radiography is one of the common non-destructive testing which employs manual image interpretation. The interpretation is very subjective and depends much on the inspector experience and working conditions. ...
    • Discontinuities detection in welded joints based on inverse surface thresholding 

      Haniza, Yazid, Dr.; Hamzah, Arof, Dr.; Hafizal, Yazid; Sahrim, Ahmad; Abdul Aziz, Mohamed; Fauzan, Ahmad (Elsevier Ltd., 2011)
      Automated detection of welding defects in radiographic images becomes nontrivial when uneven illumination, contrast and noise are present. In this paper, a new approach using surface thresholding method is proposed to ...
    • The influence of welding parameters and corrosive environment on the joint strengh of resistance Spotwelded Mild Steel Sheets 

      Shamsul Baharin, Jamaludin; Ahmad Azid Tahar, Ahmad Latiffi; Khairel Rafezi, Ahmad; Md Fazlul, Bari (Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
      In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ...
