EMAG ELC Laser Welding Systems

People in the industry can no longer imagine a car component production line without a laser welding system. This technology is a prerequisite in the use of compact, weightoptimized components, and subsequently energyc precise and adjustable, concentrated energy of the laser beam allows for high welding speeds and results in minimal distortion at the welding seam. It also ensures that co ac requiring further processing before going to the assembly line.

EMAG Laser Cell ELC EMAG ELC Laser Welding Systems are compact, laser-equipped machine tools that can - on the basis of standardized platforms and machine assemblies -be configured to match component-, customer- and project-specific manufacturing systems. EMAG ELC Laser Welding Systems have been developed and optimized -uncompromisingly - for the production laser welding of high-quality components. New workpiece geometries possible with laser welding The flexibility of laser welding processes allows for the development of new component designs. For example, it makes the trouble-free joining...

Precision The precision of the basic machine and the components used, and the workholding equipment developed and manufactured in-house, provides for accurate, reproducible results. Inherent to its functional principle the stationary optic ensures that the negative influences of beam divergence when using CO2 lasers are totally eliminated. The beam guide is a sealed and purged tube that remains clean. This ensures that the welding process encounters static conditions, an important factor for maintaining constant quality. Using fiber-guided lasers avoids the mechanical wear and tear to...

Operational safety Design characteristics such as the stationary beam guide, the use of tested components from the machine tool supply industry, the use of fully developed machine platforms and modules, state-of-the-art laser technology, a well-proven process technology and, last but by no means least, EMAG's know-how in the development and manufacture of highly efficient, high-quality production systems, can be found in every ELC. The design principle „Moving workpiece / stationary tool" minimizes the number of reclamping processes, cuts idle times and guarantees high precision,...

The ELC 160 is a modular laser welding system configurable for the most diverse requirements. At the heart of the ELC 160 lies a three-axis NC machining module, with the machine base carrying the stationary processing units. The workpieces are loaded into the spindle and transported from machining station to machining station. The machining modules are mounted on the machine base and remain stationary during processing of the components. Depending on the desired output rates the ELC 160 is also available in a DUO and a TRIO version, on which the various stations can be operated...

Manually or automatically loaded The ELC 160 is equally suitable for manual and automatic loading, with the latter using either a gantry loader or industrial robots. This offers the flexibility to adjust the ELC 160 to your own manufacturing concept and your own brand of logistics. Automatic resetting included The ELC can be equipped with several mating stations and welding fixtures (counter supports). The resetting process is numerically controlled. This allows for the flexible machining of complete component families without the need for manual resetting. Time and effort are thus reduced...

The ELC 200 H is designed for the machining of drive shafts, cardan shafts, steering shafts and other similar workpieces. This allows for the laser welding process to be used in areas which were previously the exclusive domain of friction or magnet- arc welding. The advantages of the pick-up principle are clear: workpiece loading and unloading is becoming much simpler, as the machine loads itself. The horizontal spindle and the NC tailstock ensure that families of components of different length can be machined with flexibility, and that the resetting on different workpiece geometries is...

The ELC 250 DUO also works on the pick-up principle: the spindle loads itself and positions the workpiece where the welding optic requires or takes it to other processing modules. The ELC 250 DUO features two independent machining stations that share a single laser beam source; i.e. the laser beam is switched between stations. This increases productivity (cycle time-concurrent component loading and unloading) and allows for the parallel machining of different workpieces or the inclusion of complex downstream machining operations (e.g. laser cleaning / joining / welding / brushing /...

Stationary beam guide. The swivelling spindle permits axial as well as radial welding Pick-up position Welding position, radial of the two machining stations, identical or o a be welded independently of each other.

In the case of all its welding machines EMAG's emphasis is on the stationary beam guide, with the workpiece moving from station to station. This concept is clearly directed towards process chain consolidation by means of process integration and makes the addition of auxiliary operations very easy. The ELC 250 DUO features a four-column mating press, on which mating and clamping is done in a single operation. A preheating unit and a brushing station are available as options. To meet the demands for greater productivity, EMAG welding systems also incorporate a beam diverter that can supply...

In accordance with the EMAG principle of a platform strategy with relevant automation solutions, their welding systems are able to work highly efficiently with either shuttle or robots. With floor-to-floor times of up to ten seconds and batch sizes of up to a million per year the productivity rates of automated laser welding can hardly be improved.

EMAG offers a comprehensive portfolio of quality assurance systems for your production. Besides our own process monitoring products we also integrate into our machines systems from well-known alternative suppliers. EMAG WeldCheck The EMAG WeldCheck is a compact, perfectly integrated solution to plasma monitoring of the laser welding process. It detects irregularities - like discharges, performance fluctuations, strong splatter, shielding gas failures and others - wherever they occur during the welding process. EMAG Data Recorder This software tool guarantees the 100% traceability of your...
