Spot Welded Filter Disc
Spot-Welded Filter Disc | Stainless Steel Spot Welded Wire Mesh Filter
A Spot-Welded Filter Disc is a rigid, high-strength filtration component manufactured by spot welding two or more layers of woven wire mesh at multiple contact points. Compared with single-layer or loosely stacked mesh discs, spot welding ensures stable layer alignment, enhanced mechanical integrity, and consistent filtration accuracy under pressure, vibration, and repeated cleaning cycles.
Spot-welded filter discs are widely used in polymer filtration, hydraulic systems, extrusion equipment, chemical processing, and industrial fluid filtration, where reliable multi-layer filtration and long service life are required. These filter discs are commonly produced in stainless steel, but other alloys are available to meet corrosion, temperature, and chemical resistance requirements.
Advantages of Spot Welded Filter Disc
- High Mechanical Strength
Spot welding permanently bonds mesh layers, preventing slippage, deformation, or separation during operation. - Stable Filtration Accuracy
Welded layers maintain consistent pore alignment, ensuring reliable and repeatable filtration performance. - Excellent Pressure Resistance
Suitable for high-pressure filtration systems and continuous industrial processes. - Good Cleanability and Reusability
Can be cleaned by backflushing, ultrasonic cleaning, or chemical washing without structural damage. - Wide Material Compatibility
Available in stainless steel, nickel alloys, Monel, Inconel, titanium, and other special metals. - Customizable Shapes and Sizes
Can be manufactured in round, square, oval, or custom shapes according to customer drawings.
