TigTag, an automated barcode reader, is well suited for parts that experience multiple cycles of high temperatures in excess of 2000°F (1100°C) throughout their lifetime. TigTag is a CeramiCode high-purity alumina ceramic plate mounted to a 316 stainless steel baseplate. The mounting technique is designed to permit rapid temperature cycling without stress on the ceramic plate. It can be attached to metals using small TIG or MIG welds. The 2 x 3 inch (50 mm x 76 mm) TigTag provides a large scannable barcode for traceability of pieces such as annealing covers, kiln cars, high-temperature molds and rolls. Alphanumeric characters can also be included in the laser marked message.
