Accredited Test Facilities

The Advantages of Accredited Test Facilities:
Trusted Certification Experts

The AWS Accredited Test Facility (ATF) program establishes minimum requirements for test facilities, their personnel and equipment to qualify for accreditation to test and qualify welders. This program is open to all qualified test facilities that may be a part of an independent laboratory, manufacturing plant, educational institution, or other entity.

ATFs play an integral part in the operation of the AWS Certified Welding program and have proven that they have the necessary resources to test welders to this nationally recognized and accepted program.

Accredited Test Facilities receive valuable recognition: they are listed on the AWS website for those who need to certify welders and are also advertised in the award-winning Welding Journal magazine.

The growing choice for many contractors and fabricators

Entrusting welder certification to ATF specialists makes good business sense for contractors and fabricators. Companies are increasingly realizing the shortcomings of self-qualification and switching to AWS Accredited Test Facilities to test and qualify their welders. ATFs help them to save money, improve productivity, and reduce liability by entrusting their welder certification to the experts.
