Universal welding laser is manual or CNC

Universal welding laser is manual or CNC

With one universal operating concept, universal welding laser operates as a manual welding laser; as a deposit welding laser with joystick or as a high- precision CNC system.

Rofin Laser Micro has launched a new generation of universal welding lasers: the StarWeld Select. It is not merely a manual welding laser nor is it purely a CNC-controlled system, but combining the best of both. The StarWeld Select is the result of decades of ROFIN experience, the pioneer in manual welding lasers.

One laser for all laser welding applications – for those considering introducing laser welding, the StarWeld Select is the flexible choice! With one universal operating concept, the select can be operated as an ergonomically optimized manual welding laser; as a deposit welding laser with joystick; or as a high-precision CNC system.

All process steps are controlled via the multi-functional joystick and a large multi- colour touch screen display enabling semi- automatic laser welding, CNC teach-in or jogging of heavy work pieces.

The display shows system functions including CNC control and programming clearly laid out in well- structured graphics and menus.

Especially with manual welding lasers and fully integrated system solutions, the laser enclosure design is critical.

The compact housing of the select, with its appealing design combines a large number of practical functions.

The doors vanish completely inside when opened, giving unencumbered access to a large working chamber.

The manual ports have leather safety cuffs, there are ample work piece trays and there is even a specially adapted ergonomic chair.

The entire system has a low-noise and low-vibration design which is extremely important for intensive working sessions and finest detail welding.

Innovations throughout – the generously dimensioned axes make the select a robust and, at the same time, high-precision machine.

Work pieces weighing up to 50kg and also finest precision work pieces are precisely positioned with a resolution of 10m.

Joystick technology allows full use of the motorized axis system without CNC programming.

The Track-Mode allows direct storage of manually controlled paths and can be used for deposit welding along curved contours or even for semi- automatic operations, e.g. for small- batch production.

The AreaFill option is a unique feature which allows several parallel offset welding seams to be generated for 3D surface deposit welding.

SynchroWeld automatically adjusts the weld spot sequence to the axes' travel speed and allows consistent seam welds independent of the trajectory.

Finally, the professional CNC motion system, normally only available on higher priced systems, provides the option of welding in linear interpolation mode via four axes (X, Y, Z plus rotary axis).

TrueView provides for a 100 per cent hit rate, even if operation is carried out outside the focal plane, because laser beam and microscope viewing beam path are collinear.

EasyTouch converts physical parameters which are essential for laser control (voltage, pulse power, etc.) into easily understandable graphics with the user-related parameters.

Weld spot diameter, strength and hardness – every user can handle the setting of the corresponding welding parameters without prior laser knowledge.

With the new Intelligent Pulse Management (IPM), Rofin has satisfied customers' wishes to adjust the pulse power precisely for both finest micro welds and extremely strong deep welds.

The patented Sweet Spot Resonator provides a consistently good beam quality from the very first laser pulse and is the basis for the MicroWeld-Option.

This option allows spot diameters smaller than 0.1mm, rather than the commonly achieved minimum spot size of 0.3mm.

Safe and stable – the speed- controlled exhaust system of the StarWeld Select operates with HEPA filters to remove welding fumes in a safe manner.

A closed-loop cooling circuit with large filters and cooling surfaces provides for a long lifetime and long maintenance intervals even under full- load and continuous operation.

The user is able to change consumable parts himself.

Each system undergoes an extensive endurance and vibration test before shipping, so it is ready for immediate operation without any re-adjustment on delivery.

The StarWeld Select from Rofin closes the gap between classical manual welding and costly CNC laser welding systems.

The innovative concept, packaged in a new and ergonomic enclosure – makes CNC technology profitable even for small batch production: a laser system combining excellent design with excellent performance.

Avantium provides Crystal16(tm) to all research sites of Sanofi-Aventis.

Avantium Technologies announced today an agreement with Sanofi- Aventis for the deployment of its proprietary Crystal16(tm) at all research and development centers of Sanofi-Aventis. Sanofi-Aventis has selected the Crystal16(tm) for the enhancement of its crystallization research capabilities, to increase the experimental throughput of its scientists and to be able to perform crystallization experiments on a smaller scale.

“We are pleased to provide our Crystal16(tm) platform to the global Sanofi-Aventis research organization” commented Guus Scheefhals, Chief Business Officer at Avantium, “this agreement validates Avantium's strategy to provide high- value added tools next to its services business”.

The Crystal16(tm) is a novel and proprietary platform for performing parallel crystallization experiments in 1-ml reactors. The Crystal16(tm) can be used for a range of applications in pharmaceutical and chemical research, such as solubility measurements, improving the understanding of crystallization processes and the generation of crystals for product characterization. Users of the Crystal16(tm) are capable of running 16 experiments in parallel, using minimum quantities of precious starting materials while retrieving maximum knowledge about the crystallization process and solid-state of their product.
