New AC welding process for aluminium With the Titan XQ 400 AC puls, German welding machine manufacturer EWM is aiming to revolutionise MIG welding of aluminium. molten metal falling through and with reduced distortion.

In the new acArc puls XQ welding process, the welding current alternates during the process sequence between positive and negative polarity. This makes the arc easy to control, even when using AIMg alloys. It can bridge large air gaps, including during automated application. The weld seam is clean and shiny thanks to the reduced magnesium oxide, and welding fumes are reduced. The Positionweld process ensures optimum welding during positional welding. In combination with the acArc puls XQ welding process, MIG welding seams are achieved in a TIG look.

The new acArc puls XQ alternating current welding process makes both manual and automated welding easier, and the weld seam is pure. Alongside the new MIG-AC welding process, all of the established and optimised EWM DC welding processes, such as the forceArc puls XQ, rootArc XQ and coldArc XQ, are included in the machine. The water-cooled Titan XQ 400 AC puls is specialised for aluminium welding: even the thinnest sheets can be easily and safely joined together, without the

Soft aluminium wire can be accurately fed by the Drive XQ wire feeder. With multiple options, such as a wire spool heater, electronic gas flow control, wire reserve sensor and accessories, users can configure a welding machine that matches their requirements and welding tasks. The acArc puls XQ welding process is suited to both manual and automated welding, as well as additive manufacturing of aluminium parts (3D welding) due to its low heat input.

Weld library grows to over 300 videos Xiris Automation Inc has announced the expansion of its Weld Video Library to over 300 videos showing examples of all kinds of welding applications in action, including TIG, MIG, plasma, laser, stick and electron beam welding. The videos are directly from Xiris weld cameras, with no enhancements or touch-ups. through better in-process quality control and lower process qualification costs, while providing welders with a complete video record of the weld for offline process improvement and training purposes.

Xiris specialises in developing optical equipment used for process and quality control across a number of industries. With an extensive product line, Xiris provides manufacturers with the ability to detect, recognise and interpret quality defects in their manufactured goods. Xiris Automation Inc – Canada

The Weld Video Library features colour and monochrome videos, and is categorised by welding processes. All videos are available for viewing on the company’s website.
