technology is provided by the GH Group’s latest developments in variable frequency and automatic load adjustment. The company has launched Transithermic ® generator solid-state welders, which are able to weld any tube specifications allowing for any tube diameter, thickness and material. These machines provide flexibility and economy through reductions in downtime and scrap material. The GH Group has headquarters in Spain, with subsidiaries in India, Germany, China, South Korea, Brazil, France, Mexico and Argentina. The company can provide › The GH Group will present details of its range of high frequency power supplies and induction heating equipment

Institut Dr Foerster Reutlingen is a leading manufacturer of non-destructive eddy current and magnetic flux leakage test systems. The company will provide information on its most modern generation of eddy current testers, Defectomat ® , which works with encircling through-type coils, and Circograph ® , which has rotating sensors. The company will also present its new ultrasonic test systems based on EMAT- technology. These systems include Circoson ® F for the detection of internal defects with hot rolled bars, which builds upon the AC magnetic flux leakage test system Circoflux ® , used for the detection of surface defects.

The GH Group offers an entire range of modern high frequency power supplies and equipment for induction heating applications, from MF IGBT inverters to HF Mosfet inverters. This complete range allows the use of the most suitable technology in every induction heating application, avoiding the need for obsolete and low efficiency technologies. In the area of tube induction welding, which often requires frequencies up to 500kHz, the natural, most reliable and efficient component is the Mosfet transistor. This
