CASE
STUDY #2 - Post-Welding Testing
“We have recently finished a welded construction
and the client has questioned the use of a non approved
welding consumable. The potential is that we now
have to remove all of the welds and re-weld every
joint with a welding consumable which is ISO approved.
Can you provide any advice?”
It was established from further discussions with the
client that this requirement was actually specified
in the code/contract requirement but wasn’t picked
up at the time of tender. The implication was huge
for the contractor and if the welds had to be removed
and re-welded this would have had significant cost
implications and possibly put the company in deep financial
crisis.
Weld-Class Solutions suggested that the welding consumable
that was used should be post weld re-qualified and tested
to ensure that it met the required properties and was
comparable to the specified specification. This was completed
with the approval of the 3rd party and whilst the main
welds were non-destructively tested with ultrasonic testing
to ensure that no cracking had occurred in the fabrication
at a cost to the fabricator, it was a small price to
pay compared to the potential for the original request
of a full weld removal, re-welding and re-examination.
