Cladding is often used to improve the erosion and corrosion of resistance of surfaces, whereby weld overlays of metals with very different properties from substrate extend the serviceable life of metals. Metallurgical bond between surface and substrate. Controlled arc environment. Semi –Automatic / Fully Automatic. Features: Higher production rates because of continuous processing. Less weld metals required. Automation provides for the ability to continuously make root and fill passes and higher productivity. More process consistency resulting in more consistency joints with improved weld strength , toughness and fewer repairs. Reduces human error factors and less physical stain on welders especially on long welding / cladding process. Higher quality & higher productivity, especially with long duration welds. Lower processing costs.
