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
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
We are able to carry out all types of hardening process: induction and conduction hardening as well as teeth or backside process hardening. We have developed a high expertise in steering components induction heat processes. Processes include scanning of rack teeth, pinion, ball screw and barrel, using standalone or robotics cells.

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...
Gear induction hardening SAET is a strategic supplier of all major players in the manufacturing industry. The extensive metallurgical know-how allows to push hardening and tempering process to their limits: very short heating time, minimal deformation, precise control of structure. Machine loading configuration and loading/unloading system depend on the size of the component to be treated.
Driveline components induction heat treatment With more than 300 machines installed, SAET is a strategic supplier of all major players in the driveline manufacturer industry. The extensive metallurgical know-how allow to push hardening and tempering process to their limits: very short heating time, minimal deformation, precise control of structure. Machine loading configurations range from linear transfer system to rotary tables up to stand alone and ro
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
