Transmission laser welding

Clearweld is a further enhancement of the transmission laser welding process that provides designers with a tool to laser weld clear, coloured or opaque thermoplastics. Clearweld uses materials capable of strong absorption in the NIR spectrum which impart minimal colour. It can be used in number of ways, including, but not limited to, a coating at the joint line, inclusion within the substrate or application as a consumable film. Compared with previous technologies, it offers complete freedom in the choice of colour, reflectivity and transparency of the work pieces at visible wavelengths. [Pg.586]

The methods of laser welding of fabrics fall into two categories direct welding and transmission welding. These are primarily characterized by the laser type and wavelength, as described in Table 13.16. In transmission laser welding, an absorber material... [Pg.365]
