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.

Seam tracking
system
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.
