Expanded Metal Mesh's machining tolerances and welding process requirements
Various Expanded Metal Mesh can be used in workshops, buildings, road protection, pedal nets, etc. In order to not affect the use and aesthetics of Expanded Metal Mesh, the processing error of Expanded Metal Mesh is required in the general industry. Moreover, in practical applications, most of Expanded Metal Mesh is welded on flat steel, round steel and other products, so it is necessary to improve the welding firmness of Expanded Metal Mesh.
The processing error of Expanded Metal Mesh is required during processing. On the one hand, the machining error of Expanded Metal Mesh long pitch should not exceed 1mm, and the short pitch error requirement should not exceed 2mm. On the other hand, the Expanded Metal Mesh stem thickness measurement cannot exceed 0.15 mm of the standard size.
In addition, the Expanded Metal Mesh error requirements are different depending on the thickness and width of the steel sheet. For example, when the thickness of the flat steel is 3-16mm, the processing error range should be controlled between -0.4mm and +0.2mm.
In addition to the strict control of the processing error of Expanded Metal Mesh, it also uses good welding methods, such as pressure resistance welding, arc welding and so on. When Expanded Metal Mesh is welded with flat steel, round steel and other materials, it must not only be strong, but also full soldering, no spot welding; the welding time should be well controlled so as not to affect the oxidation resistance and strength of Expanded Metal Mesh itself.
Strict control of machining error and reasonable application of welding method, flat steel spacing, welding technology, etc., ensure the firmness of Expanded Metal Mesh welding, and do not affect the performance of Expanded Metal Mesh, so that Expanded Metal Mesh can be used for decoration, protection, Support, etc., to better meet the needs of aesthetics and use functions.
