Rofin-Baasel (UK) introduces its new StarWeld tool family, for repairing injection mould and blow mould tools with laser welding. For welding of intricate moulds, the laser is capable of depositing smaller welding wires, for example wire diameters as small as 0.1 mm can be used in some materials. Typical welding wires are in the range of diameters between 0.25 to 0.4mm and there is a wide range of tool steels, stainless steels, aluminium and copper alloys available. Using tool steel wires, it is possible to deposit material with hardness in the range of 48 to 62HRC.
