ERLAS Erlanger Lasertechnik GmbH is one of the leading and most innovative high-tech companies in the field of laser application for processing metallic materials.
Its focus lies on the integration of laser technology in production processes and the application of laser’s technical capabilities in metal processing. This company serves markets which demand a high degree of precision, great speed as well as flexibility.
ERLAS is a top-level enterprise in the fields of research, development and construction. The Erlangen experts are renowned partners of those future-oriented companies and institutions, which want to apply this efficient technology.
For this purpose, ERLAS develops and implements special solutions for individual tasks. The support of and the participation in projects of the Friedrich-Alexander-University of Erlangen-Nuremberg ensure reliable access to latest research findings while developing new manufacturing concepts.
ERLAS presents its system concepts for laser beam welding and for laser beam hardening and cladding.
The systems are suitable for 2D as well as 3D processing of smaller parts such as sensor housings and large welding assemblies such as roofs for rail vehicles. The parts handling can be carried out manually or fully automated. The systems can be delivered as turnkey systems, including qualified process.
With the hardening and coating systems, components can be refined by surface treatment and are therefore primarily used in tool making from quantity 1 up to series production. Control systems and databases are used for quality assurance.
The design of the welding systems depends on the part and customer requirements: both scanners and special optics are used; the welding depths range up to several millimeters.
This plant is designed for the mass production of automotive parts: Eight individual parts are inserted manually into a workpiece carrier and then welded together fully automatically. A scanner uses the laser beam to produce 26 weld seams in 7.5 s. The robot removes the component from the welding cell and feeds it to a quality control. Six of these systems are already reliably in operation worldwide, welding a total of up to 9 million components per year.
A fully equipped hardening and cladding plant: In order to increase the working area, the industrial robot that guides the processing head is mounted on a linear axis. The other components such as powder conveyor, laser beam source, additional rotary axis and control are arranged around the system. The processing head can be equipped with an automatic changing system for powder coating and measuring tools.
Interior of a transportable processing cell for laser beam welding: On the left is the clamping device mounted on an alternating rotary table, which positions the component for welding - if necessary with an additional axis. The industrial robot guides the welding head, the laser beam is fed via a fiber optic cable. A chimney sucks off the welding emissions above the clamping device.
