Reliable Quality Assurance for Arc Welding During the Welding Process
OCT technology enables precise seam tracking and inspection in a single pass
Munich, Germany, February 5, 2026 – Lessmüller Lasertechnik GmbH, one of the leading manufacturers of quality monitoring systems for industrial welding processes, is expanding its range of solutions to include automated weld seam inspection for gas metal arc welding (GMAW). The OCT 250 stand-alone sensor system uses optical coherence tomography (OCT) as a measurement method for continuous seam tracking and weld seam inspection in real time for automated GMAW processes. The advantages for users are obvious: OCT methods are significantly more precise than conventional camera technology, the effort required for subsequent quality control is reduced considerably and the userfriendly software also enables the evaluation and documentation of analysis data. Productivity increases and scrap can be measurably reduced …

COMPANY
for a better weld – because we put quality first!
Lessmüller Lasertechnik GmbH (Laser welding quality technologies), founded as a technology company in 1990, has gradually developed under the direction of company founder Eckhard Lessmüller and managing director Christian Truckenbrodt into the market leader for quality monitoring systems in laser welding processes.
