Linde Gases, a division of the Linde Group, has launched the ARCLINE® PP, an innovative new automated welding process to produce high-quality and efficient aluminium welds by combining the best of existing welding technologies in one package.

ARCLINE PP has been designed to eliminate the compromises made when choosing between Tungsten Inert Gas (TIG) welding, which ensures high quality at longer weld times, and Metal Inert Gas welding (MIG), which has faster weld times but can create issues with weld strength and integrity.

ARCLINE PP features a positively energised tungsten electrode that provides constant cathodic cleaning of the welding area, which reduces the risk of inclusions and minimises the need for pre-weld cleaning. Secondly, the technology uses two separate gas streams, whereas other welding technologies employ only one. ARCLINE PP employs an outer shroud of shielding gas to protect the weld of impurities, and an inner stream to increase power density and improve arc stability. Finally, ARCLINE PP is equipped with a sophisticated liquid cooling system to extend the electrode’s lifecycle.

Martin Ball, Global Head of Commercial Management, Secondary Industries, Linde, said, “ARCLINE PP is a strong addition to our welding portfolio, and ensures durable and innovative aluminium welding without having to make compromises previously experienced when selecting either TIG or MIG welding.”

He continued, “By offering the high welding speeds associated with MIG in symbiosis with the high quality expected from TIG, ARCLINE PP is the perfect solution of minimal preparation and post-processing at extraordinary speed. It also generates significantly less fume emissions than MIG, enhancing occupational safety.”
