Urban outdoor metal furniture must withstand harsh environmental conditions, making weld integrity critical for safety and longevity. Key international standards govern weld strength testing: ASTM International standards (e.g., ASTM A370 for mechanical testing) evaluate tensile strength and hardness. ISO 14341 specifies requirements for weld filler metals, while EN 15085 certification is crucial for European markets, ensuring rigorous quality control. Common tests include destructive methods (tensile, bend, and impact tests) and non-destructive techniques (X-ray or ultrasonic inspection). Manufacturers must verify that welds resist corrosion, mechanical stress, and fatigue—factors essential for public infrastructure furniture like benches, racks, and shelters. Compliance with these standards not only ensures structural reliability but also enhances product lifespan in urban settings.
