Checklist : Weld Inspection

1

There are no Longitudinal or Transverse cracks in weld.

2

There are no Crater Cracks in weld.

3

No uncosumed weld wire sticking out of weld metal.

4

There is no failure of the weld metal to fuse completely at some portion of the weld zone or adjacent base metal. This includes incomplete fusion of consumable inserts

5

There is no incomplete joint penetration i.e. a joint root condition in a groove weld in which weld metal does not extend through the joint thickness.

6

There is no Irregular bead profile i.e. Underfill, valleys, sharp notches at root face, undercuts and surface ripples.

7

There is no Overlap (Roll Over/Cold Roll) i.e. The protrusion of weld metal beyond the weld toe or weld root.

8

There is no A discontinuity consisting of slag entrapped in weld metal or at the weld interface

9

There are no Gas bubbles frozen in the solidified weld metal.

10

There is no undercut i.e. a groove melted into the base metal adjacent to the weld toe or weld root and left unfilled by weld metals.

11

There is no underfill condition in which the weld face or root surface of a groove weld extends below the adjacent surface of the base metal.

12

There is no splatter i.e. globular drops of weld metal that are deposited on the weld or base material during welding, which do not form part of the weld.

13

There is no excessive weld reinforcement which is a weld metal in excess of the quantity required to fill a joint in groove welds.

14

Fillet weld leg is not undersized i.e. Weld leg is not the correct height or width , not in complaince with drawing, or weld legs are unequal.

15

Check if convex fillet weld does not have overfill or excessive weld appearance.

16

Check if fillet welds are not too concave i.e. they have sunken in or have underfill appearance.
