摘要:
为了解决管线钢管现场焊缝宏观检验传统方法存在的成品管浪费量大、耗时长、试样修磨精度不高造成腐蚀时间延长以及环境污染等问题,提出了一种基于投影原理的现场焊缝快速检验方法。该方法可快速完成试样制备以及现场焊缝焊偏量、重合量和宏观质量的快速检测。相比传统检测方法,该方法不会造成成品管浪费,腐蚀操作安全环保,检测效率能提高十几倍甚至数十倍。采用手机软件可进行图像采集、数据处理以及焊偏量和重合量的测量,检测精度和宏观照片清晰度等同实验室焊缝金相宏观检验水平,远高于现场酸蚀法焊缝宏观检验。
Abstract:
In order to solve the waste and long time of finished pipe in the traditional method of macroscopic inspection of pipeline steel pipe on site, and low grinding accuracy of the sample results in prolonged corrosion time and environmental pollution, a new method based on projective principle for rapid weld inspection on site is presented. It can quickly complete the sample preparation and the weld misalignment, overlap and macroscopic quality detection on site. Compared with traditional detection methods, this method will not cause waste of finished pipe, corrosion operation is safe and environmental friendly, and detection efficiency can be increased by ten times or more. Image acquisition, data processing and measurement of weld misalignment and overlap are carried out by using mobile phone software. The detection accuracy and macroscopic photograph definition are the same as the laboratory weld macroscopic examination level, which is much higher than the macroscopic examination of on site acid etching method.
