Elestar: "Behind an efficient industrial system, there is much more than just technology"

For steel tube manufacturers, the reliability of a production line goes far beyond commissioning: it is built over time. This is the approach taken by Elestar, a company specializing in the design and manufacture of induction welding systems for tubes, balancing technical innovation, specialized expertise, and ongoing customer support.
SiC MOSFET: the technology behind Elestar systems
At the heart of Elestar induction welding systems is SiC MOSFET transistor technology, based on silicon carbide semiconductor components. This solution makes it possible to weld both cold-rolled and hot-rolled carbon steel tubes, as well as galvanized steel and aluminum tubes, while providing tangible energy savings for tube manufacturers compared with lines based on conventional transistor technology:
- compact footprint, allowing quick and easy installation on any existing line;
- lower power losses and higher energy efficiency, approximately 90%;
- operational reliability even under challenging environmental conditions;
- consistent, uniform weld quality throughout production.
The output power of Elestar induction welders ranges from 50 to 600 kW, depending on production requirements. For stainless steel applications, Elestar also offers variable-frequency systems designed to meet the specific characteristics of this material.
A commitment that does not end with delivery
Technology, however, is only one side of the story. At Elestar, the delivery of a machine or production system is not the end of the process, but the beginning of a shared journey with the customer. The company works alongside its customers throughout the entire lifecycle of their equipment, providing maintenance, revamping, technical assistance, and specialized engineering support: a welding system may be perfect on paper, but ongoing support is what helps ensure reliability, operational continuity, and sustained performance year after year.
For Elestar, strong partnerships are built on three elements: trust, collaboration, and responsiveness. These principles guide its relationship with customers, from technical consulting through after-sales support. Being an industrial partner means being there when needed, with technical expertise, fast response times, and practical solutions.
