Arc welding machines THE EWM Hightec Welding technology and mechanisation centre, located in Weinheim, Germany, is a wholly owned subsidiary of EWM AG.

orbital system, root, filler and cover passes can be welded in a mechanised manner. This enables four times higher welding speeds and deposition rates. At the same time, quality can be improved compared to vertical down welding. Compared to manual welding, the solution is claimed to provide precision, reproducibility and evenness. The automated method enables X-ray-proof positional welding with single-V butt weld preparation or a U-weld with or without gap. This means the method meets all essential international standards. In the standard area, the weld preparation is bevelled on the construction site or in prefabrication using a straight separating cut and an angle grinder. This may result in uneven gaps during welding when the pipes are joined. The ovality of pipes of larger diameters in most cases causes considerable misaligned edges at the joint. These boundary conditions were taken into account during the development of the process. The pipeSolution process enables welding of an X-ray-proof root with solid or metal cored wires, and welding results without lack of fusion or porosity despite gap tolerances of 3 to 5mm and misaligned edges of up to 1.5mm.

The company’s philosophy is ‘all from one hand’, and it can provide EWM welding processes, experience in welding and engineering, consulting and support in every project stage, tailored solutions fitted to the budget, ‘live’ presentation of the welding tests and mechanisation solutions, and proof of principle of the welding technology. It can also supply technical training of staff, at EWM Weinheim during pre- commissioning and commissioning, and process optimisation on-site. Currently specialising in plant engineering, vessel construction and pipe construction, the challenges faced include low welding speeds due to the use of the TIG process (for safety reasons), the welding of the filler and cover passes with electrodes, and manual welding, which may sometimes be difficult at the construction site.

For more than 50 years EWM has been specialising in the development and production of high-performance arc welding machines for professional use in trade and industry. EWM Weinheim, with its team of application engineers and mechanisation specialists, offers several solutions for mechanised welding and MAG-orbital welding. In addition to standard mechanisation components, EWM Weinheim offers tai- lored mechanisation solutions including full support in the project planning stage (technical consulting, mechanisa- tion concepts, commissioning, training, parameterisation and process optimisa- tion).

EWM’s pipeSolution welding process is based on the coldArc welding process, and is designed to meet the requirements of plant engineering and pipe construction. The advantages over conventional processes are apparent both in prefabrication and at the rotating workpiece or the construction site. In conjunction with the pipeTruck MAG
