• Surface Preparation: Using a multi-stage cleaning process, we remove oxide layers and contaminants with a precision of 99.9% purity, ensuring proper weld fusion. Our chemical etching technique achieves a surface roughness of Ra 0.8μm, promoting strong adhesion between welded parts.

• Heat Management: Employing adaptive thermal control systems, we regulate pre-weld heating to within ±5℃ of the optimal temperature for each aluminum alloy, preventing brittleness and ensuring uniform material flow during welding.

• Filler Material Selection: We use aerospace-grade filler wires (such as ER4043 and ER5356) with tight diameter tolerances of ±0.02mm, matching the base material’s composition to maintain consistent mechanical properties across the weld.

• Certifications: We hold AS9100D, the international quality management standard for aerospace, as well as NADCAP accreditation for welding, ensuring compliance with the highest industry requirements.

• Testing Capabilities: Our in-house lab conducts a battery of tests, including:

• Microstructural Analysis: Using scanning electron microscopy (SEM), we examine weld microstructures to detect any defects at the microscopic level.

• Corrosion Resistance Testing: Welded samples undergo 500 hours of salt spray testing (per ASTM B117) with no signs of corrosion, ensuring durability in harsh environments.

• Non-Destructive Testing (NDT): 100% of our welds are inspected using phased array ultrasonic testing (PAUT) and eddy current testing, with a defect detection sensitivity of 0.1mm in diameter.

• Lightweight Structures: For aircraft fuselage and wing components, we specialize in welding thin-walled aluminum parts (0.3mm-2mm thickness) with minimal weight gain, achieving a weld-to-base material weight ratio of less than 5%.

• High-Pressure Components: Our welding for hydraulic and fuel system parts ensures leak-tight performance, withstanding pressure up to 3MPa in static tests and 1.5MPa in dynamic cyclic tests.

• Large-Scale Assemblies: With a production facility featuring overhead cranes with 20-ton capacity, we can handle welded assemblies up to 5m in length, maintaining alignment tolerances of ±0.1mm/m.
