  3. 3( Blank is a weld face or root that is depressed or extends below the adjacent base metal surfaces.Insufficient throat or Underfill( Blank is a weld face or root that is depressed or extends below the adjacent base metal surfaces.
  4. 4( Blank) is a groove melted into the base metal adjacent to the toe or root of a weldUndercut( Blank) is a groove melted into the base metal adjacent to the toe or root of a weld
  5. 5Excessive ( Blank ) is a type of contour formed by excessive reinforcement.ConvexityExcessive ( Blank ) is a type of contour formed by excessive reinforcement.
  6. 6( Blank ) and ( Blank ) are caused by the nonuniform expansion and contraction of the weld and base metal during the heating and cooling process of welding.Distortion and Warpage( Blank ) and ( Blank ) are caused by the nonuniform expansion and contraction of the weld and base metal during the heating and cooling ...

  8. 8( Blank ) are fractures that cause an opening or a split in the weld or base metalCRACK( Blank ) are fractures that cause an opening or a split in the weld or base metal
  9. 9A ( Blank ) crack runs along parallel to the axis of the weldLongitudinal CrackA ( Blank ) crack runs along parallel to the axis of the weld
  10. 10A ( Blank ) crack runs perpendicular to the axis of the weld.Transverse CrackA ( Blank ) crack runs perpendicular to the axis of the weld.
  11. 11( Blank ) cracks occur in the depression left at the termination of the weld bead.Crater Cracks( Blank ) cracks occur in the depression left at the termination of the weld bead.
  12. 12( Blank ) are longitudinal in the weld and originate from the face or rootWeld Metal Cracks( Blank ) are longitudinal in the weld and originate from the face or root
  13. 13( Blank ) cracks originate and grow from the toe of the weld where high amounts of stress are most commonToe Cracks( Blank ) cracks originate and grow from the toe of the weld where high amounts of stress are most common
  14. 14( Blank ) cracks are located along the root of the weldRoot( Blank ) cracks are located along the root of the weld
  15. 15( Blank ) strike is a heat-affected surface, any localized remelted surface, or change in surface profile caused by the arcArc Strick( Blank ) strike is a heat-affected surface, any localized remelted surface, or change in surface profile caused by the arc
  16. 16( Blank ) or underbead cracks occur during the cooling cycle after solidification of the weld and normally do not extend to the surface of the weldment.Heat-Affected Zone Cracks( Blank ) or underbead cracks occur during the cooling cycle after solidification of the weld and normally do not extend to the surface o...
