One machine. Two operations. Zero rework.
Hwashi's Automatic Filter Mesh Roll-Round Welding Machine combines precision roll-forming and continuous seam welding into a single automated process — flat wire mesh goes in, perfectly round and airtight filter cartridges come out. No manual rolling, no part transfer between stations, no seam misalignment.
Key Features
Integrated Roll-and-Weld Design
Separate rolling and welding machines mean double the labor, double the handling, and misalignment between operations. This machine performs both in one continuous pass — the mesh is formed and welded without ever leaving the workstation, guaranteeing perfect seam alignment.
MFDC Inverter Power Supply
Medium-frequency DC delivers faster current rise, more concentrated heat, and 30%+ energy savings vs. conventional AC. Critical for thin wire mesh where excessive heat input distorts mesh openings or burns through wires. Power factor: 0.85–0.90.
Variable Frequency Stepless Speed Control
Welding speed adjusts smoothly from 0.3 to 1.5 m/min to match different mesh types, wire gauges, and material thicknesses. No gear changes, no stepped adjustments — just dial in the speed and run.
Forced Water Cooling
Closed-loop cooling system for welding transformer, thyristors, and welding wheels. Prevents thermal drift during long production runs and extends component service life. Stable weld quality from the first part to the last.
Programmable Welding Parameters
Store up to 101 welding programs, each with custom settings for current, speed, roller pressure, and overlap ratio. Switch between programs instantly on the touch screen — no trial-and-error setup when changing cartridge models.
Horizontal & Vertical Welding Wheel Options
Welding wheel orientation selectable based on cylinder diameter and production layout. Horizontal wheels for standard cylindrical cartridges; vertical wheels for specific geometries or inline integration.
