MULTIMET® coated electrodes are typically made from nickel-rich alloy consumables that are tailored to handle the differences in thermal expansion and metallurgical properties when welding dissimilar metals. The composition often includes carefully controlled amounts of chromium, molybdenum, and iron to boost corrosion resistance and high-temperature strength. The electrode coating ensures a stable arc, a smooth weld bead appearance, and easy slag removal. Weld deposits usually demonstrate high tensile strength, good ductility, and excellent toughness, resulting in crack-resistant joints that perform reliably under mechanical stress.
MULTIMET® coated electrodes are extensively used for welding dissimilar metals, such as carbon steel to stainless steel and stainless steel to nickel alloys, as well as for buffer layer applications. They are perfect for the fabrication, repair, and maintenance of pressure vessels, boilers, heat exchangers, piping systems, and refinery equipment. Commonly found in the petrochemical, power generation, shipbuilding, and heavy engineering sectors, these electrodes provide strong, corrosion-resistant welds that ensure a long service life even in demanding operating conditions.
