Things You Need to Know about Welded Wire Mesh

High quality welded wire mesh is used in a variety of industrial applications. Wire mesh is a structure of intertwined wires with intersections welded together at regular intervals with equal gaps. They are used for commercial and industrial purposes. Typically, welded wire mesh is made of orthogonal wires joined by a resistance welding process. 

A patterned plate lead wire grid should be used. It uses an automatic CNC welding machine to make welded mesh to your exact specifications. There are various diameter configurations and wire spacing options to customize their design. The following are the basics of industrial welded wire mesh.

Wire spacing

The spacing of welded wire mesh is indicated by measuring from the center of the two wires or by measuring the opening between the two wires. Standard wire spacing is 1", or you can choose a custom welded wire with the spacing that fits your application.

Wire diameter

Welded wire mesh is available in a variety of diameters. You can choose the right diameter for the desired strength. To accurately determine the wire diameter, you should use the decimal format rather than the specification format.

Edge conditions

There are basically two types of edges in wire mesh. They include trimmed and untrimmed wire mesh. There should be a proper spacing around the trimmed mesh. This perimeter can also be balanced or reduced to stay within the desired dimensions. You should prefer the outer wire overhang when looking for untrimmed edges. It should be equal to the screen spacing. In these grids, the tail length can also be customized upon request.

Quality Inspection Procedures

Manufacturers should follow strict internal standards to ensure the consistency of welded wire mesh. There are different quality checks used to test the size and strength of the mesh. They are documented throughout the production process using torque tests and welded installation grids.

In addition to this, you should also follow proper maintenance and protection procedures to ensure the durability of the wire mesh. These are the factors to consider when selecting these meshes.

How to distinguish the varieties of welded wire mesh and get high quality welded wire mesh? Now we will give some tips. Welded wire mesh looks simple, but in fact it requires a high level of technical support. The standards are for three aspects: wire diameter, mesh size and weld firmness. The following are the quality requirements for welded wire mesh.

Welded joint requirements

First, the welded joints must be strong enough when welding the wire mesh. There is no leakage, incomplete welding or wire mesh like scrap iron after welding. So what kind of welded joints are qualified? For example, two wire diameter 3mm welded wire mesh, double wire stacked total height of 6mm, after welding the best double wire weld stack height should be between 4-5mm. The weld joint is too shallow leading to poor welding. Welded joints are too deep, the support force is weakened and it is easy to break.

Reasonable size tolerance

The size of general construction welded wire mesh is different from the size of high precision mechanical equipment. So the general requirements of welded wire mesh are not particularly precise in size. During the welding process, the thermal expansion and contraction of the wire mesh usually causes a certain deviation, so there must be a reasonable deviation. The general diagonal tolerance is within ±5mm, and the mesh size tolerance is within ±2mm.
