Check with the welding school offering the program to determine education prerequisites or other requirements for enrollment.

Earn the Certified Welder (CW) certificate from the American Welding Society (AWS) by contacting one of the Illinois testing facilities, such as Illinois Valley Community College, to register for testing. Once your weld has passed inspection by the Certified Welder Inspector, he will send your test results and registration fee to the AWS. Your certification will come in the mail in four to six weeks.

Maintain your certification by sending in proof of work every six months. Your employer must sign a statement attesting that you work in the welding field for which you are certified. Failure to maintain renewal will result in your certification being revoked.
