New press kit ''HybWeldCut''
A faster, more reliable, versatile technology, which reduces the stress felt by operators
A Charleroi SME develops a ground-breaking welding machine for special steels, which pairs laser and conventional resistance welding technology.
To meet the challenges of the European steel industry, including the development of special[1] steels with high added value – the only credible response to the mass production of Chinese and Indian steel - Europe launched a European Innovation Partnership on Raw Materials (EIP) which fosters innovation through the value chain of steel, from exploration and extraction, to efficient processing, recycling and substitution. In this context, an SME from Charleroi, SA Malex, associated with a Walloon research centre, CEWAC (Walloon Research Centre for Assembly and Control of Materials), developed a technology which is the only one of its kind in the world. Indeed, in Europe, current steels are more and more efficient, but they have become difficult to resistance weld – the main technique used to connect coils[2] in the steel industry.

[1] From steels for prestressing cables to controlled expansion nickel iron, special steels cover a very vast range of use and physical and mechanical properties. This includes alloy and non-alloy structural special steels, carbon chromium steels, non-alloy and alloy tool steels, high-speed steels, stainless and heatresisting steels, anti-corrosion alloys, steels and alloys with special physical properties.
[2] Consist in joining end to end two hot or cold-rolled steel sheet reels.
