Resumen:
Una pyme británica ha desarrollado un sistema de deposición por láser a medida que puede emplearse en la fabricación y reformulación de componentes metálicos de gran tamaño (3m x 2m x 2m). El proceso permite obtener una microestructura de grano fino que no necesita tratamiento térmico posterior. La deposición por láser tiene la ventaja de realizarse a baja temperatura, evitando la deformación de los componentes. Se buscan empresas en los sectores de petróleo y gas, producción de energía, automoción, energías renovables, agricultura y ferroviario con el fin de establecer acuerdos de servicio.

Tittle:
Robotic laser deposition powder metallurgy capability for manufacturing and reworking of very large metal components
Summary:
A UK SME has developed a bespoke laser deposition system which can be used for fabrication, coatings and reworking of very large components up to 3m x 2m x 2m. The company is looking for service agreements with industrial sectors that require this unique capability. This could include, oil and gas, power generation, automotive tooling, renewables, agriculture, marine and rail sectors.
Description:
Very large and expensive components that are either worn, damaged or faulty in some way can be reworked by adding new material in a laser deposition powder metallurgy process. A UK SME has developed a bespoke facility to achieve this for very large parts up to 3m x 2m x 2m.

The process uses a laser beam to form a melt pool on the surface of the component, into which a powder is fed. The powder melts to form high quality deposited material effectively fusion bonded to the surface. The laser is manipulated by a CNC robot or gantry system.

A wide range of titanium, nickel, cobalt, tungsten carbide and steel alloys can be deposited, including Ti-Al6-4V, Inconel-718 and Stellite-6.

The process results in a fine-grained microstructure meaning that post deposition heat treatment will rarely be required. The process is capable of achieving near net shapes to within 0.5mm of the desired geometry, thus a final machining operation may be required.

The company is looking for service agreements with organisations that work with large expensive components that are cost-effective to rework rather than scrap. Examples of these may include oil and gas, power generation, automotive tooling (eg panel presses), renewables, agriculture, marine and rail sectors.
Advantages and Innovations:
This process competes with processes such as TIG cladding but laser deposition has the advantage of being much lower temperature thus avoiding component distortion. A thinner layer of material can also be deposited and the process is very repeatable.

The company can also laser scan components to produce digitised 3D models of components of almost any size for customers wishing to reproduce replica components.
