Electrical effects and influencing quantities in the case of the hybrid plasma-MIG welding process

The hybrid plasma/metal-inert gas welding process is regarded as an interesting alternative to conventional gas-shielded arc welding processes. Although it has been known for many years already, hardly any functioning systems are available. The complex thermodynamic, flow-technology and electrotechnical relationships lead to a system with many influencing quantities and boundary conditions. The electrotechnical foundations and interlinks of the two processes of plasma welding and metal-inert gas welding (MIG welding) are presented.
