Tube and pipe

Struggling with high electricity bills?

“We can help!”, says Grzegorz Korzuszek. The Managing Director of EFD Induction Poland wants tube and pipe producers caught in the energy crunch to see how high-quality impeders can cut power consumption.

New Compact Weldac takes industry by storm

Since its introduction in May of last year, EFD Induction’s new Compact Weldac high-frequency induction welder has made a huge impact in the tube and pipe industry. But, to what exactly does this welder owe its success?

Remote commissioning

The introduction of EFD Induction’s new digital control system early last year has proven to be timely. As Covid-19 continues to complicate travel plans, the ability to perform remote commissioning is invaluable.

The sustainable choice

The highly efficient Compact Weldac sets you up for a green and profitable future.

High productivity with Weldac at SRM mill

Compact Weldac for induction welding

EFD Induction’s new Compact Weldac isn’t just the most compact tube welder on the market, it is also the smartest, most efficient and eco-friendly – with low costs to boot.

Tube welding: Simple arithmetic

If you’re in the market for a new solid-state tube welder, it will pay off to do the math on the new Compact Weldac.

A small revolution in induction welding

Sometimes, big things come in small packages, or, as in the case of the new Compact Weldac, in a small cabinet. Less than 1300 millimeters tall, this high-output solid-state welder uses minimal space while yielding a lot of power.

Higher production in smaller space - induction tube welding

After investing in an EFD Induction Weldac welder, Sperrin Trading Services Ltd (STS) in Northern Ireland has been able to increase their production output and free up valuable space.

Lower losses with SiC transistors

Whereas some Silicon Carbide transistors are less short circuit resilient, EFD Induction use a type which is just as rugged as IGBTs and provides higher efficiency as well as less energy consumption.

EFD Induction Weldac chosen for 16 inch mill

For SSAB Europe, the key factors for choosing an EFD Induction tube welder were smaller footprint, new advanced technology with a five-year guarantee on inverter modules and a high-power factor at any welder power level.

Marcegaglia installed a new EFD Induction WELDAC

In August 2017, Marcegaglia UK installed a new EFD Induction 400kW WELDAC high frequency tube welding system on the largest pipe mill at their UK Dudley plant.

Tata Steel invests in EFD Induction Weldacs across European plants

The excellent reliability, efficiency and robustness of the EFD Induction Weldacs make these solid-state tube welders a solid investment indeed.

Introducing SiC transistors

“After comprehensive testing of a range of different types of transistors, EFD Induction is now ready to introduce Silicon Carbide transistors in some of our high frequency, solid-state welders”, says Global Sales Director for Tube and Pipe, Peter Runeborg.

Welder upgrade improves total harmonic distortion

EFD Induction has announced that its lower-power Weldac welders will feature an option for a 12-pulse diode rectifier.

Major European pipe maker orders 750 kW ‘Weldac’

One of the largest tube and pipe manufacturers in Europe has selected EFD Induction to design, build and install a single-cabinet 750 kW / 200 kHz ‘Weldac’welder.

Weldac impresses at Chinese event

Dozens of high-level representatives from China’s tube and pipe industry recently attended a special technical seminar hosted by EFD Induction in Shanghai.

Three ways to cool down

When producing welded pipes according to API specification or similar, the weld and the heat affected zone (HAZ) have to be normalized. EFD Induction has three solutions.
