The technology is ready to use in the new GTarc machine, which is available in a three-axis version for parts up to 3m 3 and a five-axis version for parts up to 0.8m³. The machining center is suitable for producing complex and large parts made of steel, nickel, titanium and aluminum. CAM software calculates the data from a CAD modeled part, which enables the CNC unit to precisely position the welding head. The machine automatically produces the near-net-shape part, which is finished externally by a standard CNC milling machine. The modular GTarc machine allows for future upgrades, such as the addition of a pan-tilt table to the three-axis version for five-axis functionality.

With a transmission capacity of 587MVA, the prototype transformer has been tested for functionality, emissions and load level at Siemens’ transformer factory in Nuremberg. Siemens energy management power transformers CEO Beatrix Natter said of the transformer: “It makes direct-current transmission over long distances more efficient for our customers, because higher transmission voltages mean lower transmission losses.” The planned 3,284km, 1,100kV HVDC link between Changji, Xinjiang and Guquan Anhui has 12GW of transmission capacity.

The project is scheduled to be commissioned at the end of 2018.

Laying it on for precision

Gefertec GmbH offers 3DMP ® additive manufacturing technology for the production of near-net-shape metal parts. The manufacturer believes that the quality of the end result is comparable to that achieved using standard manufacturing methods. The technology is based on electric arc welding, using wire rather than powder as the original material. The final part is formed, welding layer by welding layer. Production speed can be up to 600cm 3 per hour.
