T echnology U pdate Welding frequency up to 500kHz NEARLY 10 years of successful use of a patented switching technology has proven the reliability of EFD Induction’s Weldac IGBT welder. Refinement of existing technology has improved and extended the use of readily available, reliable and standard IGBT transistors up to 500kHz. The improvements have led to lower stress and power loss in the transistors and the inverter module across the whole frequency range used for tube and pipe welding. The company states that the Weldac has proven so reliable, it warrants the welders’ IGBT inverter modules and driver cards for a total of five years of operation. EFD Induction has manufacturing plants, workshops and service centres in the Americas, Europe and Asia, with corporate headquarters in Norway. EFD Induction as – Norway Fax: +47 35 50 60 10

SERVO-ROBOT’S Power-Trac™ is a compact intelligent seam tracking system for robotic arc welding. The solution increases travel speed, eliminates defects and reduces over welding. Typical applications include earthmoving equipment, automotive components, military vehicles, and tanks and vessels. Included in the system is a large joint library that allows almost any weld seam on any material to be tracked and measured geometrically. The all-digital system makes integration to any robot fast and easy. Minimal maintenance is required, thanks to the rugged welding specific design. Servo-Robot Inc – Canada Fax: +1 450 653 7869
