From Wire to Fence: The Process of Making Welded Wire Mesh
Wire Drawing
The manufacturing process begins with wire drawing, wherein steel rods made of low carbon or stainless steel are drawn through a series of dies to reduce their diameter and achieve the desired wire gauge. This process also strengthens the wire through work hardening, preparing it for the subsequent welding process.
Welding
After the wire drawing process, the wires are arranged in a grid pattern with parallel wires running horizontally and vertically. They are then welded together at each intersection using electric resistance welding (ERW) or spot welding techniques. Both methods create strong bonds between the wires, ensuring a sturdy and durable welded wire mesh.
Electric Resistance Welding (ERW)
In electric resistance welding, an electric current is passed through the contact points between the wires, generating heat due to electrical resistance. The heat melts the metal at the contact points, and pressure is applied to fuse the wires together, creating a strong bond. ERW is an efficient and precise method for producing welded wire mesh.
Spot Welding
Spot welding is another technique used in the production of welded wire mesh. In this process, concentrated heat and pressure are applied at specific points to create strong bonds between the wires. Spot welding is known for its precision, efficiency, and minimal heat-affected zone, which helps maintain the overall strength and integrity of the wire mesh.
Cutting and Shaping
After the welding process, the welded wire mesh is cut and shaped according to the desired dimensions. This process may involve cutting the mesh into panels or rolling it into coils. Cutting and shaping can be done using various tools and machinery, such as shearing machines, guillotine cutters, or CNC-controlled cutting machines.
Surface Treatment
Depending on the material used and the specific requirements of the project, the welded wire mesh may undergo surface treatments to enhance its corrosion resistance and appearance. These treatments can include:
- Galvanizing: Applying a protective zinc coating to steel wires, either before or after welding, to protect against corrosion.
- PVC coating: Coating the wires with a layer of polyvinyl chloride (PVC) material to improve corrosion resistance, UV resistance, and appearance.
Hot-Dipped Galvanized Welded Wire Mesh
For hot-dipped galvanized welded wire mesh, the welding process is followed by a galvanization process. The welded wire mesh is submerged in a bath of molten zinc, which forms a protective layer on the wire surface, providing excellent corrosion resistance. There are two main methods for hot-dipped galvanization:
- Pre-galvanization: In this method, the steel wires are galvanized before welding, ensuring an even coating. However, the welding process can damage the zinc coating at the intersection points, which may require additional treatment to restore corrosion resistance.
- Post-galvanization: In this method, the welding process is performed first, followed by the galvanization process. This ensures that the entire welded wire mesh, including the welded intersections, is protected by the zinc coating. However, the process can be more complex and time-consuming than pre-galvanization.
PVC-Coated Welded Wire Mesh
For PVC-coated welded wire mesh, the welding process is followed by the application of a PVC coating. The coating enhances the wire mesh’s corrosion resistance, UV resistance, and appearance. The process involves the following steps:
- Pre-treatment: The welded wire mesh is cleaned and prepared for the PVC coating. This may involve removing any surface contaminants or applying a primer for better adhesion.
- PVC coating: The wire mesh is passed through a PVC powder, which adheres to the wire surface. The coated mesh is then heated, causing the PVC powder to melt and form a uniform layer around the wires.
- Cooling and curing: The PVC-coated welded wire mesh is allowed to cool, and the PVC coating hardens, providing a durable and attractive finish.
Quality Control and Inspection
Throughout the manufacturing process, quality control measures are implemented to ensure that the welded wire mesh meets industry standards and customer specifications. This may involve visual inspections, dimensional checks, weld strength testing, and checking the integrity of the surface treatments.
Packaging and Shipping
The final stage involves packaging the welded wire mesh for shipping, either as rolls or flat panels. Protective packaging materials, such as plastic wrap or wooden crates, may be used to prevent damage during transportation. The packaged welded wire mesh is then shipped to customers or distributors for use in various applications.
