The hexagonal quartz welding plate is a special functional device formed by high-purity molten quartz (SiO₂ purity ≥ 99.99%) through precision welding technology, creating a mechanical anchoring structure at six corner points. Its honeycomb mechanical configuration offers superior stress distribution uniformity (stress concentration factor reduced to 1.05) and deformation resistance (stiffness increased by 40%) compared to the four-corner welding plate.
