Expanded silicate in welding technology

High temperature proven during formation, the processed expanded silicate “Rotocell“ plays a critical role during the submerged arc welding process with its important contribution to quality and efficiency. For decades “Rotocell“ the expanded silicate has been used in welding technology for the submerged arc welding process. Submerged arc welding (SAW welding, EN ISO 4063: Process 121) is a fully mechanised process used to achieve high deposit rates. It is mainly used for industrial large-volume welding seams or thick-walled components. Usually, the powder is fed automatically and protects the weld from oxygen by forming slag and improves the conductivity of the arc gap. The main application areas include structural steel and high alloy steels in thicknesses from 2 to 100 mm, in shipbuilding, tank construction, towers for wind turbines, pipelines and rail carriers.
