Certified Welder (CW) Quickcheck for Custom Programs
Free Online CW Verification Service:
here and you will be redirected to the quick check page for the
AWS/ITI Sheet Metal Worker's CW program. There you will be asked
to enter a CW (IA#) number in order to verify the certification status
of the welder. This number can be found on a wallet card produced
by the welder. The search will return the certification number, a
name, and an expiration date for that individual.
