Laser cutting machines, laser welding machines, and laser marking systems use high-powered lasers to cut, trim, perforate, weld, join, or mark a variety of materials in plate or sheet form. They are used to process metals, plastics, semiconductor wafers, electronic materials, human tissue, and medical devices. Unlike plasma cutting systems, which are not suitable for cutting non-conductive materials, laser cutting machines are very effective in processing plastic, wood, textiles and other dielectric or insulating materials. Some laser cutting machines and laser welding machines provide versatility beyond just two dimensional (2D) devices such as XY or gantry cutting tables. For example, 3D laser processing equipment welds, cuts, drills, machines, surface treats and/or marks complex three-dimensional parts. Laser cutting and laser welding systems that provide 5-axis machining are also available. Related equipment operations for laser cutting machines and laser welding machines include laser drilling and perforating, laser forming and cladding, laser heat treatment, laser marking and scribing, laser soldering and brazing, laser welding, micromachining and trimming, tube processing, web slitting, and continuous feeding.
