What Is SI Certs and How Can It Train Me for CWI?

What Does a CWI Do?

Certified Welding Inspectors (CWIs) are employed all over the world. ICC Structural Welding Inspectors mainly inspect commercial structural steel. CWIs, on the other hand, are capable of inspecting any type of welding you can imagine, including product manufacturing, aerospace, underwater dam repair, oil and gas, refineries, and much more. These industries are willing to pay good money for CWIs to help increase weld quality, which in turn saves them money down the road.

"A good CWI knows how to read any set of welding code they come across, as well as inspect welds, procedures, and qualifications to the requirements of that code. SI Certs' online training course prepares you to do just that."

Today, CWIs can make well over $100,000 per year. This certification is in-demand. Companies are bending backwards to hire CWIs because they need them to finish their projects.

Passing the CWI Test

However, you’ve probably heard... the CWI exam is no joke. The American Welding Society, or AWS, offers the exam but the organization does not publish the pass rate. Long-time members in the welding inspection industry estimate that 70% fail the first time they take the test.

The CWI codes and material are complex and there are a lot of reference books to learn and understand. You’re going to have to study hard for many hours to pass the test.

The CWI Test Structure

Consider how intense the test is. The test is 6 hours long, made up of (3) 2-hour parts. Not only do you have to learn the concepts but you have to deal with time pressure. Should this be a source of worry? No, because with SI Certs’ CWI course, we walk you through every step of the way.

The Certified Welding Inspector Test Breakdown
The American Welding Society (AWS) Certified Welding Inspector (CWI) test is made up of three separately timed parts.
Welding Fundamentals
Closed Book – 150 Questions, 2 Hour Time Limit
Uses welding tools, plastic weld replicas, and fake project specifications – 46-50 Questions, 2 Hour Time Limit
The AWS D1.1 or API 1104
Open Book – 60 Questions, 2 Hour Time Limit

Online Prep Course

Until now, we’ve prepared for the exam by attending a week-long, in-person seminar. But this traditional way is becoming outdated. We believe these seminars are inadequate for many people because they teach too much information in a short amount of time.

"We've heard stories of people getting overwhelmed because they sit in class for over eight hours each day and then study for a couple more hours before going to bed. They literally just study, eat, and sleep for a whole week."

Cramming all that learning in one week is not a great recipe for success. The schedule is too intense. While some memorization takes place, learning and mastering the concepts does not. Therefore, by the time a person takes the test, their brains are so fried that they predictably fail on test day.

What if you could take a course with a more reasonable schedule? You can.

With the SI Certs online CWI prep course, you have the option of learning the material at a pace that won’t stress you out. Our students can take up to several months to go through the course. By the time they sit down to take the exam, they are prepared and relaxed. They are able to breeze through the test with time to spare.

Since our course is online, you don’t have to spend money on hotels, plane tickets, and meals. Plus, you can continue your weekly work schedule and earn money while learning. There’s no need to miss time from work.

Other online courses require you to be at your computer at certain times, or have fixed start dates that are months out. However, SI Certs does not have these requirements and limitations. Start studying anytime, even right now!

Online Learning

Online learning is the new frontier of education and research has shown that it may be more effective than in-person classroom learning.

For example, the U.S. Department of Education, in a report entitled Evaluation of Evidence-Based Practices in Online Learning, looked at 99 studies that compared online and classroom performance for the same course. They found that students who took some or all of the course online scored in the 59th percentile for tested performance, versus classroom students who scored in the 50th percentile.

Also, MIT, one of the most respected universities in the world, compared the academic performance of online and classroom students for one of their physics classes. The university found that online students performed just as well as their traditional counterparts. Further testing showed that online students learned slightly more than classroom students. You can learn more about this study in the research paper, Learning in an Introductory Physics MOOC: All Cohorts Learn Equally, Including an On-Campus Class.

As we’ve moved into the 21st century, there’s been a rising trend of college students taking classes online. Check out the graphic below by the Babson Survey Research Group.

Growth of Online Education

The studies above and this trend demonstrate that more and more people are discovering that the Internet is a great place to learn new things and improve your career.

CWI - Required Training Hours
"In a CWI classroom seminar, you'll have around 40 hours of teaching. But we've found that you really want 80 hours, done at your own pace, to learn the material."

We provide 80-90 hours of instruction instead of 40 hours. You’ll want those extra hours because that’s when we cover advanced topics. Learning about these topics can be the difference between a passing score and a failing score.

You also have our attention. During the course, you can post any questions in our live web-chat interface and we’ll respond to them within 48 hours. The teacher of the course, Matt Owens, CWI, MSI, passed the test on his first try in 2010, and he has over 10 years of experience in the industry. He is a skilled instructor, and he’ll be answering your questions through our integrated messaging system in our site. Help is literally one click away.

CWI Instructor & Technical Expert

"Hello, I'm Matt. I've been involved with steel inspection for the past 10 years, and construction inspection in general for much longer. I first took and passed the CWI exam in 2010. The exam was extremely difficult, and most of those I took the test with failed. They were so overloaded with information and memorization that they were unable to truly understand the concepts and have confidence in what they knew."

"Over the years I have had the opportunity to manage and lead dozens of inspectors. In trying to get my inspectors certified, I've seen first-hand what works and what doesn't. I understand how the curriculum needs to be delivered so that students can best grasp and master the material. And when my inspectors bring me back a passing certification, my smile is as big as theirs!"

CWI vs. ICC Welding

You may be wondering what the difference is between SI Certs’ ICC Welding course and CWI course. The ICC course is designed for students wanting to earn their Master of Special Inspection certification, or students who are new to welding inspection. The CWI training can be taken without having ICC Welding certification, but if you are new to welding we strongly advise you to take our ICC Welding course before taking CWI. Our ICC Welding course lays a foundation to prepare the user to understand the concepts we go into great detail on for CWI.

SI Certs explains how to become a CWI, along with all requirements for becoming a CWI in Part A of our CWI course, available for purchase.
