Three ways to identify welded wire mesh

Three ways to identify welded wire mesh

How to identify the varieties of welded wire mesh in order to buy good quality ones? Now we will make a specific introduction. Welded wire mesh looks simple, but it requires a high level of technical support. The standard addresses three aspects: wire diameter, wire mesh size and weld firmness. The following are the quality requirements about welded wire mesh.

 

Requirements for welded joints

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

 

Reasonable dimensional tolerance

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

 

Control of wire diameter of welded wire mesh

Here is not too much explanation, we all know that the standard tolerance of the export wire diameter should be controlled within ± 0.05mm.
