EMAG ELC 6i

The EMAG ELC 6i is the next-generation evolution of EMAG's proven ELC 6 production laser welding platform, integrating up to six process steps in a single machine for complete component assembly. The "i" designation signals an integrated, multi-process approach that goes far beyond conventional laser welding: the ELC 6i combines laser cleaning, inductive preheating (optional, two stages), joining/pressing, laser welding, and marking into a single automated production cell. This process consolidation eliminates multiple standalone machines and the handling between them.

The ELC 6i handles workpieces up to 300 mm in external diameter and 300 mm in height, with axial welding diameters from 75 to 200 mm and radial welding diameters from 75 to 250 mm — matching the work envelope of the ELC 6 while adding substantially more in-machine process capability. The machine uses proven multi-axis kinematics from the ELC platform with a fixed transfer system that achieves cycle times under 20 seconds, with up to 18 workpiece carriers circulating through the various process stations.

The Siemens Sinumerik One control — the latest generation Siemens CNC — replaces the 840D sl used in older ELC models, providing enhanced processing speed, digital twin capability, and future-ready connectivity for Industry 4.0 production environments. The system includes two stations for raw-part placement and two stations for removing finished assemblies, enabling continuous production flow without interruption. Changeover time under 20 minutes supports mixed-model production scheduling.

With a footprint of approximately 21.5 square meters, the ELC 6i replaces what would otherwise be a line of five or six standalone machines: a cleaning station, induction heater, press, laser welder, and marking system. For automotive powertrain manufacturers producing high-volume assemblies that require multiple thermal and mechanical joining processes, the ELC 6i provides the ultimate in process consolidation and floor space efficiency.
