T echnology U pdate Welding innovations

EWM Hightec Welding exhibited at this year’s EuroBLECH fair the latest equipment and process innovations from its research and development team: alpha Q, Taurus, Phoenix, rootArc ® and pipeSolution ® . The company also presented its range of products, from high-tech power sources to torches and an updated range of filler materials. In addition to the process versions forceArc ® and coldArc ® , theMIG/MAG inverter welding power source alpha Q can now also handle the new pipeSolution. This brand new process demonstrates its advantages in the construction of pipelines, pipe systems and pressure vessels: quick and dependable MAG root welding with high quality, whether for manual or mechanised welding (eg orbital technology), with or without an air gap, on unalloyed or low alloy steels, with solid wires. The arc is especially powerful and therefore directionally stable no matter what the thickness of the material, and in all positions of the sheet or the pipe. Once the root has been welded, the alpha Q changes the process on demand and welds the filling layers and the final pass with a pulsed MAG process. This innovation is an economical alternative to TIG welding. The economic advantage of the welding process is additionally increased if the power source is equipped with a twin case, eliminating the need for a conversion of the filler wire and shielding gas or a second machine. The repertoire of the alpha Q also includes standard MIG/MAG welding TIG (Liftarc) and the MMA welding process. The possible applications of the Taurus EUROMAQUINA, Spain, offers integrated tube processing equipment from the coil to the galvanised pipes in bundles. Using the latest technology, together with its partners the company can now provide integrated solutions as turnkey projects, such as mother tube production, stretch reducing mill (hot rolling), galvanising, threading, packaging or shot blasting-galvanising. Increasingly present in the Middle East, the company now also has offices and agents in ASEAN countries. The company’s key concept is not to consider steel construction, tube making,

power source have been extended: the Taurus Synergic series can now also handle welding with forceArc and is equipped with the rootArc process. This innovation features a stable, soft short arc – suitable for simple and dependable root welding, easy bridging of the seam gap and out-of- position welding. The new, compact Phoenix 335 puls with integrated wire feed supplements the Phoenix range of fully digital inverter welding power sources. Thanks to the plastic casing, the unit is now more ergonomic and significantly lighter. Equipped for almost any welding task and especially convenient and easy to use, the Phoenix is suitable for use in construction sites, assembly work, workshops or production halls. In addition to the previous MIG/MAG pulsed and standard processes, forceArc, TIG (Liftarc) and MMA welding, it now also operates with the rootArc process version. The Phoenix 335 is easy to use and control, and can be simply extended with a cooling module and a transport vehicle, without any tools or special knowledge. The effectiveness of a process chain is determined by all of its components. For this reason EWM carries out its own development and production of MIG/MAG galvanising and material handling as independent issues, but to look for the best possible product design and process flow in terms of durability of final structure (product), reuse of valid mechanical and thermal components of actual plants (investment budget), and looking at the feasibility of automatic galvanising (efficiency) and avoiding non value-adding steps.

torches. The EWM torch standard, which was first presented at the last EuroBLECH, has now demonstrated its worth in practice. Users report that the optimised geometry of the EWM contact tip (M7 to M9) ensures excellent heat dissipation and perfect current transfer. The tip remains cooler and the extremely low spatter formation of the EWM process is significantly reduced. Reworking is reduced even further and the service life of the wearing parts is also extended, which in turn has a positive effect on both changeover times and production costs. For mechanised welding, the company supplies new AMT series torches with various angles for currents from 220 to 550 amps. The wearing parts of the torch are identical to those of the hand torch and are therefore of the same quality. Process reliability and a long service life of the contact tip are especially important with mechanised welding. Each interruption of the welding process causes a standstill of the system, which results in great losses of production.
