In the field of steel structure manufacturing, the processing quality of welding robots directly affects product performance and safety of use. A heavy machinery manufacturing company has increased the welding qualification rate to 99.9% by implementing comprehensive quality management, setting a benchmark for the industry.
The company has established a strict equipment maintenance system. Before work every day, technicians will conduct a comprehensive inspection of the welding robot, including mechanical arm precision calibration, welding gun centering debugging, wire feeding system inspection, etc. Deep maintenance is carried out once a week to replace wearing parts and clean key components. These measures ensure that the equipment is always in the best working condition and the equipment failure rate is controlled below 0.1%.
In terms of process control, the company has developed an intelligent welding management system. The system monitors key parameters such as welding current, voltage, speed, etc. in real time, and automatically records the welding data of each weld. When the parameters exceed the set range, the system will immediately alarm and stop the operation. At the same time, a welding process database has been established to preset the optimal welding parameters for different materials and structures to ensure stable welding quality.
Multiple detection methods are used in the quality inspection link. Each weld must undergo visual inspection, ultrasonic flaw detection and X-ray inspection. Destructive tests are also carried out on key parts to ensure that the welding strength meets the design requirements. All test data are entered into the quality traceability system to achieve full process quality monitoring.
Through the implementation of these measures, the company's welding quality has been significantly improved, the product repair rate has been reduced by 80%, and the customer complaint rate has been reduced by 90%. This successful experience shows that only by establishing a complete quality assurance system can the technical advantages of welding robots be fully utilized to ensure the processing quality of steel structure products.
