Recently, DONGDING TUBE organized a specialized skills training for eddy current testing personnel. The training was lectured by Yu Hai, a senior expert at DONGDING, and focused on the standardized execution of process discipline, the combination of theoretical knowledge with practical operation, and the identification and handling of typical defect patterns. It aimed to enhance eddy current testing capabilities for products including stainless steel welded pipes, stainless steel seamless pipes, stainless steel coiled tubes, stainless steel heat exchanger tubes, precision stainless steel welded pipes, and precision stainless steel seamless pipes.
During the training, the expert first emphasized the importance of process discipline in eddy current testing. From strict execution of testing standards to standardized setting of instrument parameters and standardized operation of testing procedures, the expert provided a systematic explanation based on actual tube production practices. Regarding the weld quality of stainless steel welded pipes and precision stainless steel welded pipes, as well as internal defect control of stainless steel seamless pipes and precision stainless steel seamless pipes, the expert required trainees to strictly follow process procedures and execute process requirements to ensure accurate and reliable test results. For products with high surface and internal quality requirements such as stainless steel coiled tubes and stainless steel heat exchanger tubes, greater attention must be paid to testing details to eliminate missed inspections and misjudgments.
In the lecture, the expert deeply analyzed the principles of eddy current testing and systematically explained the formation mechanisms, signal characteristics, and judgment methods of typical patterns such as flash arcs, weld penetration, cracks, and liner tubes through case studies. Combining the common defect types in production of stainless steel welded pipes, stainless steel seamless pipes, stainless steel coiled tubes, stainless steel heat exchanger tubes, precision stainless steel welded pipes, and precision stainless steel seamless pipes, the expert analyzed pattern characteristics one by one to help trainees improve defect identification and handling capabilities.
This training effectively improved the theoretical level and defect identification ability of eddy current testing personnel, laying a solid foundation for ensuring the quality of stainless steel welded pipes, stainless steel seamless pipes, stainless steel coiled tubes, stainless steel heat exchanger tubes, precision stainless steel welded pipes, and precision stainless steel seamless pipes. DONGDING TUBE will continue to strengthen professional skills training and safeguard the quality of every tube with a testing standard of striving for perfection.
