My name is Leandro Gutierrez, and for over a decade, welding has been more than just my job—it’s been my way of life. I’ve put in the hours on pipelines, compressor stations, refineries, and fabrication shops. I’ve felt the heat of the arc, watched the sparks fly, and worked under the pressure of knowing the weld had to be right the first time. Those years in the field taught me discipline, attention to detail, and a deep respect for the craft.
When I set out to earn my AWS CWI certification, I didn’t just pass—I achieved exceptional scores. That success wasn’t luck. It came from understanding how the theory in the books connects to the work we do every day in the field. But I also saw how many others preparing for the exam struggled to make that same connection. They had the drive but needed a guide who could bridge the gap between classroom knowledge and real-world application.
That’s why I created Lone Star CWI. This isn’t a course written by an academic or textbook author—it’s built by a welder, for welders and industry professionals. My mission is simple: to give you the tools and knowledge to not only pass the AWS CWI exam but to truly understand it. By combining textbook fundamentals with insights from real-world experience, I want to help you step into the exam—and onto the job site—with confidence.
At Lone Star CWI, our vision is to empower skilled welders and industry professionals to become certified welding inspectors with unwavering confidence and a comprehensive understanding of the field.
