Welded wire mesh

Plastic extrusion, pharmaceutical drugs, roadways, and high-rise apartments. These are just a few of the many industries that thrive when mesh is properly integrated. 

With dozens of mesh solutions, such as woven wire mesh and welded mesh, on the market, it&#;s up to the engineers, project managers, and lab technicians to select the right one.

But which material works best: welded mesh or woven wire mesh? 

&#;What will the mesh be used for? What material am I working with? When do I need the mesh?&#; are all questions you must ask yourself when determining whether to use welded mesh or woven wire mesh.

W.S. Tyler has been a leading wire mesh manufacturer for over 140 years and are here to ensure you integrate the right mesh solution.

This article will establish what welded mesh and woven wire mesh are, how each material is made, what they are used for, and how they compare in cost. At the end, you should have a better understanding of which mesh will work for you.

What Is Woven Wire Mesh?

Woven wire mesh is best described as a predetermined number of metal wires interlaced together to form a roll or sheet of wire cloth that upholds a specific pattern. When weaving wire mesh, parameters such as wire diameter, opening (aperture) size, micron rating, weave pattern, width, and length can be customized to your specific needs.

How Wire Mesh Is Made

When woven wire mesh is woven, a designated amount of wires are wrapped around a warp beam that gets placed into a specialized weaving loom. The warp wires are then placed into heddle frames that split them into 2 or more sets depending on the weave/pattern of the mesh.

As the loom operates, the heddle frames push the different sets of wires up and down as a wire, known as the shute wire, is driven in between the wires. After being threaded through the wires, the up and down motion of the heddle frames locks the shute wire into place.

Woven Wire Mesh Applications

One advantage woven wire mesh has over welded mesh is that the mesh opening can be much finer. This is because as the wire diameter gets smaller, the harder it is to weld the mesh without damaging the wires or compromising the openings of the mesh.

Having said that, the finer mesh openings of woven wire mesh make it perfect for virtually any filtration, particle analysis, or screen printing application.

What Is Welded Wire Mesh?

Welded wire mesh is a series of steel wires that are welded at the wire cross-sections using one of several welding techniques, most commonly TIG and spot welding. As the wires undergo a thorough welding process, the opening size of the mesh is, for the most part, permanent.

How Is Welded Wire Mesh Made?

When welded wire mesh is made, spools of wires are threaded into a weld mesh machine, much like threading wires into the heddle frames and reed of a woven wire loom. Separate spools of wire are then fed through a straightener and pre-cut to match the desired width of the mesh. 

As the machine runs, the wires from the spools are fed through the machine. The pre-cut wires are then placed into a mechanism that lays them across the wires being fed from the spools. 

After being laid in place, the machine applies a uniform weld at each cross-section simultaneously. Depending on the length of the welded wire mesh panel, the mesh is made available in welded wire mesh rolls or operators take the mesh, cut the access material, and place it into piles of cut-to-size pieces.

Welded Wire Mesh Applications

As thicker wires must be used to withstand the welding process, welded wire mesh is regarded as being the more rigid and durable of the two materials. This heightened strength makes it perfect for perimeter fencing, protective caging (animals and equipment), and concrete wire mesh sheets.

How Does Cost Compare Between Woven and Welded Wire Mesh?

As illustrated previously, welded mesh and woven wire mesh are produced differently. That said, other than the threaded wires throughout the loom, the weaving process of woven wire is mostly automated.

Producing welded mesh, on the other hand, is a lot more hands-on. An operator must thread wire through a straightener before it is cut into the crossbars.

Additional wire must also be threaded through the machinery itself.

Now, the mechanism that accurately places the crossbars must constantly be fed material. These bars are commonly fed by hand.

Lastly, the access material that protrudes off the edges must ensure optimal results. Again this process is commonly done manually when the mesh is not being rolled by the machine.

With that, the labor costs and heavy-duty wire that must be used causes welded mesh to be the more costly of the two.

Which Mesh Is Right For Me?

As with all mesh solutions, the application will determine whether you should use welded mesh or woven wire mesh.

If you are working with rugged material that requires a mesh that is sturdy and durable, welded wire mesh may be a good fit. Welded mesh is also a good fit for extremely corrosive conditions as it can be galvanized for extra protection.

If mesh strength is not an issue and you&#;re looking for a cost-effective mesh solution that can offer smaller mesh openings than ¼&#; for filtration purposes, woven wire mesh is right for you. As woven wire mesh is produced predominantly with stainless steel, which is too resistant to corrosive material, the fact that it often has shorter lead times than welded mesh should also be considered.

Implement the Ideal Wire Mesh Specification

At first glance, woven wire mesh and welded may seem identical, however, they are two materials that carry a lot of differences. That said, no matter which mesh you chose to implement, knowing the right mesh specification is just as important as the material itself.

Woven wire mesh is a series of wire interlocked together during the weaving process and is ideal for filtration, particle analysis, and screen printing.

Welded mesh is a mesh sheet that is welded at each cross-section and is ideal when heavy-duty mesh openings are needed.
