New EMMEDI SiC HFI Welder

New EMMEDI SiC HFI Welder
NEW EMMEDI MosWeld Silicon Carbide (SiC) HFI welder, displayed publicly for the first time and sold from FABTECH show display in Chicago 2017. This new welder will be installed in the midwest USA early December and it will forever change the face of HFI welding technology. Using high current capable SiC (Silicon Carbide) transistor technology, the EMMEDI MosWeld SiC system delivers the same frequencies as former Mosfet units. But here is the kicker, pe

Tube heating – customized solutions – topic of the month
Stainless steel tubes, austenitic or ferritic, require a full body heatingto recover the original hardness. The in-line process is mainly used with AISI 300, AISI 400, duplex, superduplex and titanium pipes for various applications such as petrochemical, furniture, automotive, food and beverage. The pipe is heated and then cooled by means of water showers. Read more at Emmedi_Customized_Heating.pdf

SOLID STATE WELDERS – Topic of the month

SOLID STATE WELDERS – Topic of the month
MOSWELD is the ultimate solid state power supply using MOSFET transistor technology The circuit topology is current-fed inverter (CFI) with an inductance located between the DC and the HF stage, thus the inverter is naturally protected against load short circuit. The output circuit is a parallel resonance type: load and inverter impedances are naturally matched, then no output transformer is required and therefore overall efficiency increases. Typical la...

IGNITION OF A LOW FREQUENCY INDUCTIVELY COUPLED PLASMA AT ATMOSPHERIC PRESSURE

IGNITION OF A LOW FREQUENCY INDUCTIVELY COUPLED PLASMA AT ATMOSPHERIC PRESSURE (Guy CHICHIGNOUD, Yves DELANNOY, Francois COCCO, Pascal RIVAT, Luigi NATALE) Abstract Inductive plasmas used in process applications are classically coupled to high frequency coils (several MHz), needing a high voltage power supply, and therefore difficult to operate. In this work, plasma torches are operated at 400kHz with several solid state generators, ranging from 50kW
