(8)
Stray arcing: The welder should ensure that stray arcing does not occur, but the
weld and adjacent parent metal should be examined for cracking caused by accidental
stray arcing as they may need to be removed by mechanical means.
(9)
Inspection of weld repairs: When welds fail to comply wholly or in part with the
acceptance criteria and unacceptable defects are to be removed, the following items
should be checked during the repair operation.
(a)
Removal process: Ensure that the specified means of removing the defect,
e.g. chipping, hand milling or machining is used correctly.
(b)
Partially removed weld: Check that the cut out portion is sufficiently deep and
long to completely remove the defects. Ensure that at the ends and sides of the cut
there is a gradual taper from the base of the cut to the surface of the weld metal, the
width and profile of the cut being such that there is adequate access for re-welding.
(c)
Completely removed weld: When a cut has been made through a faulty weld
and there has been no serious loss of material, or when a section of material
containing a faulty weld has been removed and a new section is to be inserted,
check that each weld preparation is reproduced in accordance with the welding
procedure.
