Product Description

Hwashi Automatic Seam Welding Machine for High-Strength Joints with Adjustable Welding Wheel Speed and 360° Rotational Capability

Automatic Filter Mesh Roll-Round Welding Machine

Product Overview

Every industrial filter cartridge starts the same way — a flat sheet of woven wire mesh that must be precisely rolled into a cylinder and seam-welded without damaging the delicate mesh structure. Get the rolling wrong, and the cylinder is out of round. Get the welding wrong, and you burn through the mesh, distort the openings, or leave a seam that leaks. Either way, the filter fails.

Hwashi's Automatic Filter Mesh Roll-Round Welding Machine solves both problems in a single, integrated process. Flat mesh feeds in; a perfectly round, seam-welded filter cartridge comes out. No manual rolling. No separate seaming step. No rework. Whether you're producing filter cartridges for water treatment, oil & gas separation, automotive filtration, or food processing, this machine delivers consistent cylindrical geometry and airtight weld seams — shift after shift, year after year.

What Makes This Machine Different

Roll and Weld in One Seamless Cycle

Traditional filter production requires two separate operations: roll the mesh into a cylinder on one machine, then transfer it to a seam welder. That's twice the labor, twice the handling, and twice the chance of deformation between steps. This machine integrates both functions — automatic feeding, precision roll-forming, and continuous seam welding — into one continuous cycle. The mesh never leaves the machine between rolling and welding, so alignment is perfect every time.

Gentle on Mesh, Tough on Seams

Woven wire mesh is unforgiving. Too much pressure during rolling crushes the weave. Too much heat during welding melts through the wires or distorts the mesh openings around the seam. This machine's rolling mechanism applies calibrated pressure to form a smooth cylinder without deforming the mesh structure, while the MFDC seam welding system delivers concentrated, controlled energy that creates a strong, leak-proof seam without overheating the surrounding mesh.

Quick Changeover for Multiple Cartridge Sizes

Filter manufacturers rarely produce just one size. This machine accommodates a range of cartridge diameters and lengths with quick-change roll tooling and programmable welding parameters. Switch from a 2-inch water filter to a 6-inch industrial cartridge in under 20 minutes — swap the forming rolls, select the stored program, and you're running. Up to 101 welding programs can be stored, each with tailored current, speed, and overlap settings.

Airtight Seams That Pass Every Test

For filtration applications, seam integrity isn't optional — it's the difference between a filter that works and one that bypasses contaminants. The continuous seam welding process produces overlapping weld nuggets that form a gas-tight, liquid-tight joint. Whether your filter operates at low pressure in a residential water system or at high differential pressure in an industrial hydraulic circuit, the seam holds.

Designed for 24/7 Filter Production

The forced water-cooling system for both the welding transformer and the seam welding wheels ensures stable thermal performance during extended production runs. Variable-frequency stepless speed control allows smooth, consistent welding speed adjustment to match different mesh types and wire gauges. No overheating, no downtime for cooling, no variation in weld quality as the shift progresses.

Machine Configuration

The machine is designed for standalone operation or integration into automated filter production lines:

Configuration	Standalone Unit	Inline System
Best For	Batch production, multiple sizes	High-volume, single-size production
Loading Mode	Manual or automatic feed	Fully automatic from decoiler
Changeover Time	15–20 min	20–30 min
Footprint	Compact, single-station	Custom line layout

Core Systems

Roll-Forming Mechanism

Precision-engineered forming rolls shape flat wire mesh into a smooth cylinder with consistent diameter and roundness. Roll gap and pressure are adjustable to accommodate different mesh thicknesses and wire gauges without crushing the weave pattern. The forming process produces cylinders ready for immediate seam welding — no secondary forming step required.

Seam Welding System

Continuous roller seam welding (also known as roll welding or resistance seam welding) creates an overlapping series of weld nuggets along the longitudinal seam. The welding wheels apply both pressure and current simultaneously as the cylinder rotates, producing a continuous, leak-proof seam. Available in horizontal or vertical welding wheel orientation depending on cylinder diameter and production layout.

MFDC Power Supply

Medium-frequency inverter DC power supply delivers precise, controlled welding energy with superior power factor and 30%+ energy savings compared to conventional AC systems. The fast current rise time is ideal for thin wire mesh, delivering enough energy for a strong nugget without prolonged heat input that would damage surrounding mesh.

Feeding System

Servo-driven mesh feeding with adjustable speed and length control. Compatible with pre-cut mesh sheets or continuous mesh strip from a decoiler. Feeding accuracy ensures consistent overlap at the seam for reliable weld quality on every part.

Control System

Industrial PLC with color touch screen HMI. Intuitive parameter setup for welding current, welding speed, roller pressure, and overlap ratio. Real-time monitoring of all key process variables. Welding data exportable via USB or network. Password-protected operator levels prevent unauthorized parameter changes.
