How to improve the quality standards and testing level of wind power processing and welding in Dalian

The welding quality of Dalian wind power processing is directly related to the reliability, safety, and service life of wind power equipment. Improving its quality standards and testing level is the key to ensuring the healthy development of the wind power industry. Here are some feasible methods and measures.

1、 Improve quality standards

Optimize process specifications

Thoroughly study the process characteristics of wind power processing and welding, and develop more detailed and scientific process operation specifications based on welding technology and equipment. Clarify the standards for key processes such as welding parameters, welding sequence, and assembly requirements to ensure that each welding and assembly process has clear guidelines to follow. For example, for welding of different parts and materials, corresponding current, voltage, welding speed range, as well as preheating, post heat treatment requirements are specified to ensure the consistency of weld quality and performance.

Strengthen personnel training

Improving the skill level and quality awareness of welders is the core of enhancing quality standards. Regularly organize welder training, including training on welding theory knowledge, practical operation skills, and quality control points. Encourage welders to participate in professional skill certification exams to improve their professional competence. At the same time, strengthen quality education for the entire welding team, so that everyone understands the importance of quality standards, and create a good atmosphere where everyone pays attention to quality.

Introduce standards

Pay attention to the new quality standards and regulations in the international and domestic wind power industry, and timely introduce and apply them to actual production. Communicate and cooperate with industry enterprises to learn their quality management experience and quality standard system. For example, drawing on foreign wind power equipment manufacturing standards, refining and improving the appearance quality and internal defect detection standards of welds, so that our product quality can be in line with international standards.

2、 Improve detection level

Using detection equipment

Invest in purchasing non-destructive testing equipment, such as ultrasonic flaw detectors, radiographic flaw detectors, magnetic particle flaw detectors, etc. These devices can more accurately detect defects inside the weld seam, such as pores, cracks, slag inclusions, etc. At the same time, by utilizing digital detection technology, the accuracy and efficiency of detection can be improved, and real-time monitoring and data analysis of weld quality can be achieved. For example, using an automated ultrasonic testing system can quickly and comprehensively inspect large welded structures and generate detailed inspection reports.

Improve the testing process

Establish a comprehensive testing process from raw materials to finished products. When raw materials enter the site, strict quality inspection is carried out on welding materials to ensure that they meet quality standards. During the welding process, real-time intermediate inspection is carried out to promptly detect and correct welding defects. Finished product testing should be comprehensive and meticulous, with strict non-destructive testing and visual inspection of all welds to ensure product quality is qualified. At the same time, record and analyze the detection data to provide a basis for quality improvement.

Train professional testing personnel

The professional level of the testing personnel directly affects the accuracy of the testing results. Strengthen the training of testing personnel to familiarize them with the operation and testing principles of various testing equipment, and master the correct testing methods and techniques. Regularly conduct skill assessments and comparative tests to enhance the professional competence and sense of responsibility of testing personnel. At the same time, encourage testing personnel to participate in technology research and innovation, explore new testing methods and means, and improve the level of testing.

Establish a quality feedback mechanism

The test results should be promptly fed back to the production department and quality management department. For quality issues discovered, it is necessary to quickly organize analysis of the causes and take effective corrective measures. Establishing a quality traceability system can quickly identify the source of problems and fundamentally solve quality issues. By continuously summarizing experiences and lessons learned, continuously improving quality standards and testing processes, we aim to achieve continuous improvement in the quality of wind power processing and welding.

In short, by improving quality standards and testing levels, the quality of wind power processing and welding in Dalian can be effectively enhanced, providing a solid guarantee for the sustainable development of the wind power industry.
