nLight acquires weld inspection technology developer

Fibre laser manufacturer nLight has acquired Plasmo Industrietechnik to add machine vision and analysis products to its manufacturing solutions.

Plasmo is an Austrian-based provider of automated quality assurance and diagnostic solutions, primarily for the welding and additive manufacturing markets. The solutions will complement nLight’s industrial laser portfolio.

Jake Bell, general manager for industrial lasers at nLight, commented: ‘Combining lasers with Plasmo’s real-time process monitoring solutions provide customers with a significant advantage as they develop, qualify and produce increasingly complex laser-printed or welded parts, particularly for high volume electric vehicle production.’

Laser welding is expected to play a role in battery production, as well as other manufacturing steps in electric vehicle production plants.

Plasmo includes in-line triangulation cameras for inspecting weld seams at a processing speeds of 30kHz, as well as sensors incorporated directly into welding optics for seam inspection.

nLight will also expand its European footprint with the addition of Plasmo’s Germany and Austrian sites.
