Our expertise includes Visual Testing for surface defects, Magnetic-Particle and Liquid-Dye Penetrant for surface-breaking flaws, and Ultrasonic Testing for deep volumetric examination of critical welds.

Welder Certification

NWIS LLC provides professional welder certification and performance qualification testing in accordance with AWS, ASME, and API standards. Our certified inspectors administer supervised weld tests, perform visual and nondestructive examination, and issue proper documentation to verify that welders are qualified for the specific process, position, and material required by your project.

Our AWS Certified Welding Inspectors (CWI) utilize advanced NDT methods—including Visual Testing (VT), Magnetic-Particle Testing (MT), Liquid Penetrant Testing (PT), and Ultrasonic Testing (UT)—to ensure full compliance with AWS, ASME, and API codes."

Frequently Asked Questions

Find answers to common questions about us and the services we provide.

Delivery time varies depending on the volume of applicants we receive within the week of your exam. The bend tests are typically performed the day following your exam, and upon receiving a passing grade, certificates and WPQRs could take a few days to complete and send to the applicant, so you should receive your new certificate/WPQR within a week after your exam.
We allow applicants up to an hour to take their for plate tests and up to 2 hours for pipe tests.
Prices vary depending on the specifications required for the certification you wish to test for. The most common plate test we provide under the AWS D1.1 structural code starts at $350 per test.
The most common test we provide is a 3G(vertical position) plate test under the AWS D1.1 structural code
There are many factors to consider when deciding what is right for you. A few of the most important factors you need to consider when deciding on specifications for your test are the following: What material do you typically weld on, or plan on welding? What welding process do you currently use, or plan on using? What positions do you typically weld in, or plan on welding in? For instance, if you plan on applying for a job at a company that mostly performs welds for structural applications, you may consider a test in the 3G(vertical position), SMAW(welding process) and A36(Carbon Steel material) which is what most structural welders obtain to start.
The “3” represents the position in which you weld while the “G” represents the type of connection. For instance, 4G represents a groove weld welded in the overhead position, while 2F represents a fillet weld welded in the horizontal position.
You can weld in the following positions: 1 Flat(f), 2 horizontal(h), 3 vertical(v) and 4 overhead(oh).
