The source of best welding quality - process control virtual machine
Today more than 5000 Virtual Machines control various arc- and spot welding systems in active production facilities worldwide, especially in the automotive field.
What is the Virtual Machine?
All welding processes as well as processes of thermal spraying of any kind, whether hand-held or robot-controlled, must be controlled very precisely and flexibly.
Physical parameters, e.g. the material type of the materials to be welded, material thicknesses, current, voltage, wire feed, electrode forces, process gas flow and time have to be optimally matched in different applications and also different welding technologies. For example, in arc wire spraying the requirements vary up to an extremely individual and fine process management. At the same time, the exact reproducibility of these complex processes (process reliability) must be ensured in industrial applications.
This is exactly what has been done successfully by the process control "Virtual Machine" (Virtual machine according to Puschner, P.) at ELMA-Tech since its foundation. The Virtual Machine can therefore rightly be regarded as the essential technological core of ELMA-Tech welding technology.
As a welding process control, it solves the management of complex joining processes with a maximum reproducibility and with the least possible programming effort. As a process control for thermal spraying (e.g., wire arc spraying), it provides a fully flexible adjustment of spray parameters for optimized adhesion and extremely fine injection molding.
Historical continuity and fundamental practical knowledge
Since 1970 Prof. Dr. Peter Puschner has developed state-of-the-art control and power electronics for welding technology. The basic techniques involved have found wide acceptance in the entire welding technology and mark the innovation point in electronic welding equipment. Worldwide patents emphasizes the innovative nature of the ELMA-Tech developments.
In 1997 a new control system for technological processes was implemented on the basis of these technological developments: the virtual machine. The virtual machine is used as welding process control in the by now third generation exclusively by ELMA-Tech and establishes the technological top-level that ELMA-Tech takes nowadays.
