Weldac


EFD Induction

EFD Induction is the largest induction heating company in Europe and offers solutions for a wide range of applications.
ARB Metal is the exclusive sales agent for Tube & Pipe industry in Turkey with the main focus on High Frequency Induction/contact welding of pipes, tubes and profiles using the WELDAC range.
WELDAC is the most advanced, reliable and efficient high frequency welding system in the world. Utilising the latest transistor technology, there is a 5-year warranty on inverter modules/driver cards for all WELDAC HF welders.
Other key benefits of WELDAC include:
 

High-output solid-state welders

  • More output: Continuous electronic load matching secures full power output across a wide range of tube sizes.
  • More uptime: Short-circuit-proof, safe and reliable operation.
  • Unrivalled efficiency: Diode rectifier with a constant power factor of 0.95 at all power levels, and an efficiency factor of 85-87%.
  • Eco and energy friendly: High efficiency saves energy and reduces cooling water consumption.
  • Easy to operate: An easy-to-use control panel with a minimum of manual settings makes the Weldac extremely easy to operate.
  • Wide range of power sizes: From 50 kW up to 2200 kW. A frequency range of 60-500 kHz.
  • Modern modular design: The small, compact footprint saves valuable floor-space and simplifies in-line integration. Up to 1100 kW available in a one-cabinet solution.
  • Complete system: Consisting of a diode rectifier, ­inverter modules, output section, busbar and operator control system.
  • Unmatched warranty: Five-year warranty on Weldac inverter modules and driver cards.

Annealing/Heating of Pipes/profiles
EFD Induction also offers annealing systems for tube & pipe, applications include
•    Seam annealing – inline heat treatment of weld seam
•    Full body annealing of both magnetic and non-magnetic tubular products
•    Pre-heating and post-heating for various processes (e.g. painting/coating)
•    Brazing of heat transfer tubing (boiler, refrigerator and HVAC)
•    Preheating and stress relieving of OCTG pipe ends
•    Coating and post-weld heat treatment (PWHT) of oil and gas pipes
•    Customized solutions for every dimension and alloy type


EFD Induction annealing systems utilise our SINAC range of universal heat generators with IGBT technology.
