Aluminum is the world-wide material of choice for high speed patrol vessels and other vessels up to 120 metres in length. Although highly suitable for its purpose, the material poses many challenges for welding due to its high thermal conductivity and the presence of the natural aluminum oxide on the surface. The vessels are generally used in demanding applications, which means that their quality needs to be world class. For example, Nautic's 30-metre long aluminum high speed crew and patrol vessel, OPS 301, can be used for transporting workers to and from oil rigs. Safety is the main priority, as it carries up to 24 seated passengers with accommodation for 5 crew and 12 passengers.
Die Lösung von Kemppi
Nautic took Kemppi's Kempact MIG 2530 and FastMig Pulse (now available as FastMig X Regular) welding equipment into use with the SuperSnake subfeeder, which enabled welding even at great distances to the welding machine. The Kemppi solution was praised for its user-friendliness in parameter selection. The one-knob operation of FastMig Pulse together with WiseFusion software function was received especially well among the welders. All positions could now be welded with one setting thanks to WiseFusion's ability to ensure optimum arc length. In addition, SuperSnake's extended reach quickly transformed into productivity, safety and ergonomics benefits at the shipyard.
Overall, the versatility and multifunctional flexibility of Kemppi machines compared to their cost assured Nautic of a great choice for their production. What's a better combination than Kemppi welding equipment paired with the skilled welders at the first factory in Africa to have a 100% weld pass rate?
