Manufacturing companies in both the mechanical and electrical sectors of industry are now beginning to adopt lasers for an increasing range of materials processing applications, including cutting, drilling, welding and surface treatments of both metals and non-metals. In some of these applications the process or product is completely novel, but for many others the compatibility of the laser with computer numerically controlled (CNC) and robotic techniques, its flexibility in operation, or other practical factors, are helping it to compete with older established fabrication technologies. Some illustrative applications drawn from nuclear, aerospace, and mass production industries are discussed in detail. The paper also touches briefly on the potential importance of laser technology for other industrial applications such as measurement, information technology and chemistry, as well as a few ‘high profile’ scientific applications.
