Introduction To Welded Joints

Welded joints achieve high-strength connections between components through metallurgical bonding (increasing load-bearing capacity by 30-50%). They are widely used in hydraulic systems, petrochemicals, and other fields, capable of withstanding complex mechanical forces such as pushing, pulling, and torsion. Their surface smoothing treatment reduces contact surface wear (increasing wear resistance by 20-35%), significantly extending the service life of machine tools, ships, and other equipment. In high-pressure pipelines and other applications, welded joints effectively prevent media leakage with their 0.01MPa-level sealing performance, ensuring the safe operation of chemical plants and power plants. Furthermore, in fields such as construction and bridges, weld grinding processes can achieve a surface finish of Ra≤3.2μm, improving the overall aesthetics of the project.
