Although welded steel mesh for mining has many advantages such as high strength, corrosion resistance, easy installation, and economy, there are also some disadvantages that cannot be ignored. The following is a detailed analysis of its shortcomings:
1, Welding quality issues
1. Uneven quality of solder joints: Due to various factors such as welding materials, welding equipment, and worker skills during the welding process, it is difficult to ensure that the quality of all solder joints is uniform and consistent. This may result in insufficient strength of some welding points, and even cracking of welding points, thereby affecting the service life and safety of the entire steel reinforcement welded mesh.
2. Welding cracks: The welding process is difficult and the welding quality is difficult to guarantee, so welding cracks may sometimes occur in the welded mesh of mining steel bars. This not only affects its aesthetics, but also reduces its service life, and even poses a threat to the personal safety of users.
2, Limited anti-corrosion performance
The material of welded steel mesh for mining is mostly ordinary steel, which has relatively poor anti-corrosion performance. During use, if anti-corrosion treatment is not carried out in a timely manner, especially in harsh environments such as humidity, acidity, and alkalinity, the welded steel mesh is prone to corrosion such as oxidation and rusting, which accelerates its corrosion process and shortens its service life.
3, The impact on workers' health
In the production process of welded steel mesh, if traditional welding methods such as manual arc welding are used, the arc radiation and smoke generated during the welding process may have adverse effects on the health of workers. Long term exposure to such an environment may expose workers to occupational health risks such as skin burns and respiratory diseases.
4, Production efficiency and cost issues
1. Low production efficiency: The production efficiency of steel bar welded mesh that relies entirely on manual welding is low and cannot meet the needs of large-scale production. This will not only increase production costs, but also affect project progress.
2. Material waste: The manual welding process requires a large amount of auxiliary materials such as welding rods, and due to the instability of welding quality, some materials may be wasted.
In summary, there are certain shortcomings in the welding quality, anti-corrosion performance, worker health, and production efficiency of the welded steel mesh used in mining. Therefore, corresponding measures need to be taken in the use and production process to overcome these shortcomings, such as improving the level of welding technology, strengthening anti-corrosion treatment, improving the working environment, and adopting automated welding production lines. At the same time, when selecting welded steel mesh for mining, it is also necessary to comprehensively consider its advantages and disadvantages as well as the actual needs of the project.
