The quality inspection process of welded mesh is a key link to ensure its product quality, performance and safety. Generally speaking, the quality inspection process of welded mesh includes the following aspects:
1. Appearance inspection
1. Welding quality: Check whether the welding point is flat, and there should be no defects such as welding slag, welding nodules, false welding, and leaking welding. These defects will affect the strength and service life of the welded mesh.
2. Mesh neatness: Check whether the mesh is uniform and neat, and whether the edges are intact. The neatness of the mesh directly affects the screening efficiency and appearance of the welded mesh.
3. Galvanized layer quality: For galvanized welded mesh, it is necessary to check whether the galvanized layer is uniform and smooth, and there should be no defects such as fading, peeling, and bubbles. The quality of the galvanized layer is directly related to the corrosion resistance and service life of the welded mesh.
4. Surface flatness: Check whether the surface of the welded mesh is flat, and there should be no defects such as bumps and waves. Surface flatness affects the appearance and use effect of the welded mesh.
2. Dimension measurement
1. Mesh size: Use measuring tools to check whether the width and length of the mesh are consistent with the specified production size.
2. Wire diameter and spacing: Check whether the diameter and spacing of the wire meet the specified standards. These parameters directly affect the load-bearing capacity and screening efficiency of the welded mesh.
3. Material and chemical composition inspection
1. Chemical composition analysis: Use chemical composition analysis to detect whether the raw materials used in the welded mesh meet the standard requirements. Especially for galvanized welded mesh, it is also necessary to check whether the zinc content of the galvanized layer meets the standard.
2. Physical and mechanical properties testing: Including tests of physical and mechanical properties such as tensile strength and yield strength. These tests can evaluate the load-bearing capacity and durability of the welded mesh.
4. Strength test
Perform strength tests such as tensile, compression, and bending on the welded mesh to evaluate its load-bearing capacity and stability in actual use. These tests help ensure the use effect of the welded mesh in harsh environments.
5. Other inspections
1. Cleanliness inspection: Ensure that there are no impurities attached to the surface of the welded mesh to avoid affecting the use effect.
2. Logo inspection: Check whether the product logo is clear, accurate, complete, and reliable. Product identification is the proof of product identity and an important way for users to understand product information.
The quality inspection process of welded mesh is a comprehensive and systematic process, involving inspections of appearance, size, material, chemical composition, strength and other aspects. Through a strict quality inspection process, it can ensure that the quality of welded mesh meets relevant standards and requirements, and provide users with high-quality products and services.
