EFD Induction’s new Compact Weldac isn’t just the most compact solid-state welder on the market, it is also the smartest, most efficient and eco-friendly.
Weldac is EFD Induction’s family of high-output, solid-state tube and pipe welders. The Weldac family covers a wide range of power sizes; from 50 kW up to 2200 kW. and a frequency range of 60-500 kHz.

The EFD Induction Weldac: What it is, how it works and why you should care.
The authors evaluate the parameters that influence welder performance and scrap production during changeover in the high-frequency tube and pipe welding process.
This article explains some basic principles of solid-state welder design that are crucial for maintaining operation under various conditions.
The authors evaluate the parameters influencing weld quality and scrap production in high-frequency tube and pipe welding. The paper focuses on the welder. Two stages of the production process – steady state operation and non-ideal conditions – are investigated. The parameters involved are ripple in output power and short circuits in the load.
The article investigates the impact that geometrical changes in the weld zone have on weld frequency and the Heat Affected Zone (HAZ).
