EXCLUSIVE REPORT - The EFD Induction Weldac

The EFD Induction Weldac: What it is, how it works and why you should care.

Article collection

A collection of four articles published in the Tube & Pipe Technology magazine.

Weld setup, variable frequency and heat affected zones

The article investigates the impact that geometrical changes in the weld zone have on weld frequency and the Heat Affected Zone (HAZ).

A brief introduction to one of the lesser-known uses of induction heating: glass fiberizing.

Next time you visit a funfair or circus, take a few minutes to see how candyfloss—known as cotton candy in the US—is made.

Maximising output in high-frequency tube and pipe welding

The authors evaluate the parameters that influence welder performance and scrap production during changeover in the high-frequency tube and pipe welding process.

Maximizing uptime in high-frequency tube and-pipe welding

This article explains some basic principles of solid-state welder design that are crucial for maintaining operation under various conditions.

Consistent quality in high-frequency tube and pipe welding

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.
