GENERAL REASONS FOR DEFECTS


The importance of weld quality is increasingly felt as we go ahead with the fabrication of sophisticated products using higher strength materials combined with critical design consideration. However, defects are likely to be present in materials produced at economic cost. Defects are generally introduced because of:

  • Lack of know how & know why as well as experience.
  • Welding process characteristics.
  • Base metal composition.
  • Defective welding filler metals.
  • Joint design.
  • Welding environment (wind, fit up, temperature, etc.)
