The welded wire mesh machine (also known as a spot welding machine) is specialized equipment that uses a digital control system as its core and achieves automatic welding of metal wire intersections through resistance spot welding technology. Its core value lies in replacing the traditional decentralized manual electrode welding process. By arranging longitudinal and transverse metal wires at preset intervals and completing full intersection welding, it achieves standardization, efficiency, and large-scale production of wire mesh. It serves as the core equipment for manufacturing metal mesh products in fields such as construction, transportation, and protection.
This equipment is compatible with carbon steel, stainless steel, coated steel, and non-ferrous metal wires, with wire diameters ranging from 2 to 12 millimeters. It can process various mesh sheet specifications from 0.5 m × 1 m to 3 m × 6 m. The welding strength can reach more than 85% of the original strength of the raw materials, far exceeding the quality of manual welding.
Composition of Key Equipment
The complete set of equipment consists of six core systems that work together to ensure the welding process is precise and efficient:
Wire feeding and blanking system: Includes a longitudinal wire feeding mechanism and a transverse wire blanking device. Longitudinal wires are automatically conveyed through a pneumatic clamping device, while transverse wires are driven by patented disc technology to achieve single-strand blanking with a positioning accuracy of ±0.5 mm.
Welding execution unit: Equipped with a dedicated water-cooled transformer for welded wire mesh, the output power is adjustable in steps. It is paired with multiple sets of upper and lower electrode blocks, capable of completing the synchronous welding of more than eight weld points at one time.
Mesh pulling mechanism: Adopts a continuous reciprocating design with pneumatic clamping and servo drive. The spacing of transverse wires can be infinitely adjusted by inputting parameters through the touch screen. Multiple spacing specifications can be set within the same mesh.
Frame and pressurization system: The main frame is welded from thick steel plates and profiles. The upper electrode is pressurized by a cylinder with precisely adjustable pressure. The downward and upward speeds are controllable, reducing impact loss on the workpiece.
Electronic control system: Centered on a PLC programmable controller and touch screen, it supports welding parameter setting, process monitoring, and fault alarms. The operation interface is highly visualized, enabling beginners to learn quickly.
Cooling system: Uses water cooling to cool the welding transformer and electrode blocks in real time, preventing component wear caused by high temperatures and extending the service life of the equipment.
Standardized Production Process
Parameter presetting: Input parameters such as mesh size, longitudinal wire spacing, transverse wire spacing, and welding current on the touch screen; the system will automatically match the corresponding welding program.
Raw material feeding: Place the longitudinal wires into the feeding mechanism, load the transverse wires into the blanking bin, and start the automatic operation mode.
Wire conveying: The pneumatic wire feeding device conveys the wires at set intervals to the welding station.
Transverse wire blanking: The drive disc blanking mechanism precisely positions a single transverse wire at the intersection of longitudinal wires.
Synchronous welding: The cylinder drives the electrode block downward, and the transformer outputs current to complete hot-melt welding at the intersection points. Multiple rows of weld points can be welded simultaneously.
Mesh pulling and forming: The mesh pulling mechanism clamps the edge of the mesh sheet and pulls it to the next welding position at the preset interval, repeating the welding process.
Finished product cutting: After the mesh reaches the set length, the automatic cutting device performs cutting, and the finished product is conveyed to the storage area.
