“Due to their inherent efficiency, repeatability and ease of maintenance, the use of lasers in automobile manufacturing has increased dramatically over the last decade.
“While most laser-based systems are predominantly used to cut parts, a significant number are employed in other applications such as welding, marking and additive manufacturing.
“During the laser welding process, changes in process parameters can affect the quality, size and properties of a welded joint. Any such changes that do occur may compromise the mechanical behavior of the welded component, leading to a failure in service.
“Hence, monitoring and controlling the laser welding process has become vitally important to ensure the quality of welded joints.
“To perform this task, researchers at three European companies and institutions are working to create a laser welding monitoring and control system.
“Under the auspices of an EU-funded project called Laser equipment ASessment for High impact innovation in the manufactuRing European industry (LASHARE), New Infrared Technologies (NIT; Boadilla del Monte, Spain; www.niteurope.com) AIMEN Centro Tecnológico (Porriño, Spain; www.aimen.es) and Centro Ricerche Fiat (Orbassano, Italy; www.crf.it/en-US/Pages/default.aspx) have joined forces to develop a system that can ascertain the quality of welded sheets of steel by capturing and processing images of the welding process from an uncooled MWIR sensor.”
