As Rey has given you the link I believe,
http://files.aws.org/certification/docs/QC1-2007.pdfYou will have needed to be inspecting welds and have documentation attesting to it besides the money and an eye exam.
15.4 The SCWI and CWI requesting renewal of certification
shall attest to having no period of continuous
inactivity greater than two years in activities as described
in AWS B5.1, Specification for the Qualification of
Welding Inspectors during the previous three years of
certification.
The SCWI and CWI not meeting the requirements
of 15.4 may renew by taking the CWI Part B Practical
exam and meet the scoring requirements in 6.2.2 of
this standard.
Here is the renewal package
