Welding with two wire electrodes: Status and prospects of the optimisation of gas-shielded metal-arc welding

A variant of high-productivity metal-active gas welding is presented below. It works with two wire electrodes which are electrically insulated from each other and is designated as "Time-Twin" at Fronius. Memories of the older T.I.M.E. process relate to the increases in productivity possible with it, achieved with standard shielding gases. The information provided ranges from the objectives, the status, the application, the process itself, the appliance-technology components and the options right up to the perspectives.
