Hawk
In briefest terms.
The AWS tracks and compiles performance qualification test results on work performed by AWS Accredited Test Facilities (ATF)
If a CWI is qualifying welders, the test report usually goes to the person paying to have the work done, which is not necessarily the welder. If the work is not at an ATF, no report goes to Miami.
Many employers hold those certs/test reports. The welder does not "own" the cert. simply by virtue of passing the test.
