Automelt B20 Plus: The Standard for High-Toughness, Code-Quality SAW
For fabrication involving high-pressure, high-stress environments, such as reactors, steam generators, and pipelines, the weld metal must exhibit exceptional mechanical properties. The Ador Welding Automelt B20 Plus stands as a premium Agglomerated Basic Flux, specifically formulated to deliver high-quality, radiographic-grade weld deposits in Submerged Arc Welding (SAW) processes.
Technical Superiority and Classification: This fluoride-basic flux is distinguished by its high basicity index (approximately 3.1), which facilitates the efficient removal of impurities and the precise transfer of alloying elements. This results in weld metal with very low impurity content and excellent mechanical properties, meeting rigorous standards like AWS A5.17/A5.17M (F7A8/P8-EH12K, F48A6/P6-EH12K).15 The resulting deposit is known for its high tensile and yield strength, combined with outstanding low-temperature impact toughness.
Versatile Application Parameters: The Automelt B20 Plus exhibits a neutral behavior, making it versatile for use with both low and high manganese content wires (e.g., EH12K). It is suitable for use with both AC and DCEP current polarities and is highly effective in modern, high-productivity setups, including narrow-gap welding and tandem/multi-wire systems.
The carefully controlled grain size ensures smooth flux flow and excellent slag detachability, minimizing post-weld clean-up time and maximizing production speed.
Critical Industry Applications: Beyond general structural work, its primary use is in critical infrastructure, including the long seam and circumferential welding of pipes, and the fabrication of high-specification pressure vessels and boilers, where crack resistance and toughness at service temperatures are absolute requirements.
