Columbus State Community College (CSCC) in Columbus, Ohio, has developed a welding education platform that uses weld data capturing and video imaging technologies to train students in manual welding processes. 

The platform, called Columbus State WeldTools (CSWT), is the brainchild of Scott Laslo, skilled trades associate professor and program coordinator at CSCC, and his colleagues. CSWT works with shielded metal arc welding, gas tungsten arc welding, gas metal arc welding (GMAW), and flux cored arc welding by digitally capturing the unique welding abilities of any highly skilled welder and translating their talents and techniques into data profiles. Students then train against these data sets, called master welding profiles (MWPs), with matching video recordings and traditional instruction methods.

This innovation arrives as industries are facing a nationwide need for more welders. AWS estimates that 314,000 welding professionals will be needed by 2024 ( In addition, the overall labor participation rate has decreased by 5.4% over the past 20 years ( participation-rate-since-1990).

“[Companies are asking,] ‘How do I get the personnel we need just to keep our business within this region?’” Laslo said. “This is happening all across the United States and is definitely happening here in central Ohio.”

Laslo is confident welding positions can be filled. He thinks CSWT can transform workforce development by not only training welders more efficiently but by replicating the best welders with specific and measurable data.

“I ask a company, ‘Who is your best welder and would you mind if we clone them?’ and immediately they perk up,” he said. “Bring your welder in, we will let them weld on our equipment, and we will show you how we will use data to make an informed replication of what they do.”


A New Use for Existing Technology

CSWT works by using the Lincoln Electric Power Wave® 300C advanced process welding machine, the Lincoln Electric REALWELD® trainer, and the InterTest Inc. Visible Welding® WeldWatch® HD EDU weld tutoring station (camera system). An experienced, skilled welder starts by performing a welding process on the Lincoln Electric equipment. A computer captures variables such as travel angle, travel speed, contact-to-work distance, wire feed speed, amperage, and voltage during the welding process. These data variables build the tolerance thresholds that create the standard MWP to specifically and objectively score against.

When welding students perform a live weld against the MWP, they simultaneously record their weld with the camera system. Real-time data shows if the student goes under or exceeds various tolerances of the MWP. The camera system produces an ultra-dynamic video recording that processes out the glare of the welding arc, resulting in a homogenous image of the torch tip, weld pool, and base metal. Upon finishing the weld, the welding student and instructor see an objective score out of 100, the weld’s matching data set, and a video in a single file. From there, the instructor can review the student’s file and welded piece to analyze what was done well and what can be improved.


A Different Style of Teaching

In traditional welding training, instructors show students a demonstration, tell them about that demonstration, and have them practice. Laslo learned and then taught welding this way for 25 years. Being an AWS Certified Welding Inspector and Certified Welding Educator as well as a certified welder under numerous AWS codes, he thought there might be another way to teach.

After Laslo researched technologies, earned grant awards, and worked with the CSCC IT department to develop the platform, the CSWT took center stage in the CSCC Center for Workforce Development building in June 2021. With two instructor stations and 13 student stations, it is the main feature of many of the 22 welding courses offered at the college. Students perform and record their welds, and instructors watch every station’s weld image and data, making learning and teaching more dynamic and easier for large groups.

“If I’m at my work station and I can see their screens, see their progress, I have a very quick opportunity to see if a student is struggling,” Laslo said. “I can be more intentional in who I need to help.”


Student Perspective

Olivia Ishmael, a welding major at CSCC, and her classmates used CSWT during a lab session in their introduction to GMAW course this past fall.

“I can see if I’m going too fast in one spot or not doing the correct hand motion in the other,” said Ishmael. “I can look back to see what I need to fix and what I need to do correctly to get a good bead laid.”

Repetition and practice of live welding still happen with CSWT, just in a different way.
