Since the invention of the laser in 1960, the use of lasers has rapidly grown across various industrial sectors. Lasers enable non-contact and precise materials processing capabilities which have transformed manufacturing. Some of the key ways lasers are applied in manufacturing include cutting, welding, marking, engraving and additive manufacturing.

Laser Cutting Processes

One of the most common industrial applications of Industrial Laser Systems is laser cutting. It uses a laser beam to melt and fuse materials to cut 2D and 3D shapes from a wide range of materials. Laser cutting offers benefits like precision, flexibility and minimal heat impact zone compared to traditional cutting tools. Different laser cutting processes are used based on the material - CO2 lasers for cutting non-metallic materials, fiber and solid-state lasers for cutting metals. Lasers enabled the development of automated 3D laser cutting machines which increase productivity in job shops and manufacturing. Precision laser cutting is now extensively used in automotive, aerospace, electronics and other industries.

Laser Welding Technologies

Laser welding utilizes the intense heat of a laser beam to join similar or dissimilar materials. It offers advantages like narrow heat-affected zones, deep penetration and hermetic seals. Various laser welding methods are used in manufacturing including butt, lap, percussion and projection welding. Fiber and solid-state lasers enable high-power, high-speed laser welding applications. Automotive and appliance manufacturers use laser welding for tasks like body panel joining, exhaust system assembly and pressure vessel manufacture. The medical device industry also employs precision laser welding in minimal invasive surgeries.
