FACE TO FACE equipment( PPE) for welders. The focus was on intelligent automation, digital networking and sustainable solutions. ISMR sat down with Thomas Häusle, Chief Business Officer( CBO), EWM and MD of EWM Holding, and Alan Cauchi( Managing Director, EWM UK) at the trade show to discuss the EWM Group’ s strategy, market views, new processes and latest innovations.

New processes and innovations
“ Over the last couple of years, we have opened new EWM branches in Italy( near Milan) and France and increased our market share in key countries. We have also launched several new products; our new PPE product range is a case in point. New industry-specific processes have been developed e. g. EWM REACT, a modified short arc process for sheet metal, additive manufacturing and cladding applications. Together with our partners, the TANICS™ project was realised utilising our EWM ForceTIG welding process for production and remote welding of nuclear waste disposal vessels,” Alan Cauchi, MD, EWM UK, told ISMR.
“ The new EWM REACT welding process is one of the highlights on our stand at the Schweissen and Schneiden trade show. It is a high-productivity automation process that will unlock new opportunities for us in industry sectors, such as automotive and other sheetmetal applications in steel, high-alloy steels and aluminium for joining, cladding and additive manufacturing systems. We recently launched the process throughout Europe and beyond. We now have our first systems in place in the UK and plan some events in the coming months. We are also planning new launches for EWM REACT in new materials for both joining
Alan Cauchi, MD, EWM UK. and additive later this year,” he continued.
Compared to the short arc, the EWM REACT welding process involves up to 35 per cent less heat input with a deposition rate that is twice as high. With this welding process, users have full control over droplet transfer. Instead of uncontrolled transfer from the wire end into the weld pool, the droplet is deposited even at high welding speeds. This, says EWM, results in“ virtually no weld spatter and significantly reduces the need for finishing work.”
“ We believe that these industry-specific processes will lead to additional opportunities for us in specialist markets with major industry leaders in defence, nuclear, general manufacturing, construction etc.,” added Alan Cauchi.

Tetrix XQ 300 SiC puls
With its Tetrix XQ 300 SiC, EWM is launching a new TIG welding machine with silicon carbide semiconductors. The new welding machine was presented at the SCHWEISSEN & SCHNEIDEN trade show in Essen this September.
“ Users benefit from higher energy efficiency, lower heat generation and a longer service life. The Tetrix XQ 300 SiC puls contains silicon carbide semiconductors that set new standards in welding technology. Compared to conventional transistors, they have significantly lower switching losses, ensuring precise current control and enabling efficient conversion of the energy used into welding power. This not only reduces power consumption but also excess heat. This reduces the cooling requirements and extends the service life of the electronics,” explained EWM.
“ With the Tetrix XQ 300 SiC puls, we are providing users with a welding machine that combines high performance with the sustainable use of resources,” said Johannes Rosbach, Product Manager Manual Welding, EWM.“ Thanks to its robust design, the Tetrix XQ 300 SiC puls is also suitable for use in harsh industrial environments with its high temperature resistance, low wear and tear, stable performance and maximum conversion of the energy used. This is thanks to the silicon carbide semiconductors and the inverter technology used. In this way, EWM supports companies to increase their productivity while reducing their carbon footprint, an important step towards sustainable welding,” he concluded.
