1. Pre-weld Source Control: From material to preparation, eliminate congenital defects
Pre-welding is the foundation of quality, with 80% of the root causes of welding defects lying in pre-welding preparation. The core is "no adulteration of materials, high precision of tooling, and standardization of pre-treatment."
2. Process Strict Control During Welding: Fixed parameters scientific sequence, eliminate human deviation
The core during welding is "unchanged parameters, symmetrical sequence, controlled layer temperature, and standardized operation," which reduces deformation and internal defects caused by uneven thermal input and is key to ensuring the formation and intrinsic quality of the weld.
3. Post-weld Closed-loop Inspection: Eliminate stress non-destructive testing, ensure weld qualification
Post-welding is the key to quality verification, with the core being "stress elimination, defect detection, dimensional correction, and anti-corrosion closure," ensuring that unqualified welds are never released.
4. Finished Product Verification and Design Compliance: From static to dynamic, verify load-bearing capacity
Post-weld finished products need to pass load tests to verify structural safety, ensuring that the boom can withstand the designed static and dynamic loads, which is an important closed loop for quality control.
5. Later Operation and Maintenance and Traceability: Full life cycle control, prevent later failure
Quality control of the boom is not limited to the manufacturing phase; standardization of later operation and maintenance can effectively extend its service life and prevent later weld cracking and structural deformation.
