Improve Productivity With This New Welding Technology

By Evelyn Witterholt. 

We speak with Dave Nordentoft from Leister about Leister Quality System (LQS) technology, a new way to track productivity and improve safety while heat welding. 

For over 70 years, Leister has been an industry leader in the field of plastic welding and hot-air applications. Although they operate in a variety of industries, they are well known within the roofing industry for their innovative heat welding technology. In a recent podcast with Dave Nordentoft, Leister’s manager of roofing products, we discuss their new Leister Quality System (LQS) technology. 

Dave has been with Leister for nine years now, working directly with the roofing industry to improve the way contractors use hot air technologies. In 2017, they rolled out their LQS platform, a quality management system that tracks welding data for their geosynthetic membrane sector. Today, they have been introducing this technology to the roofing industry. 

“What we're doing here is we're taking the [welding] machine, we're able to set these parameters in the machine, and now there's a feature that we built in that's tied in with LQS. We call it monitored welding assistant,” Dave says. “What the machine's going to do is it's going to monitor each time that the weld is initiated, that nozzle is inserted and the weld starts.” 

When the welding machine is in use, LQS will be tracking how it is used for quality and safety purposes. If the machine is used outside of the welding parameters, the machine will indicate this with an alarm. All of this is done to improve the quality of the welding process and track when issues like this arise.  

“We're also tracking incoming voltage into the machine, which I think is kind of a big deal today because a lot of issues related to machine performance and optimal welding performance are tied into improper power supply,” Dave says. “Now we'll be able to see that in a data report, if there becomes some issue with how a generator's operating on a job, we would see that voltage drop.”
