CCD图像传感器用于焊接过程时,由于电弧光使其感光单元都达到电饱和,影响它获取信息的准确性和 可靠性,可采用滤光片来减轻弧光的干扰。表面张力过渡技术有很低的线能量、极低的飞溅率和极高的电弧稳定性。 因此,在三峡工程大型水轮机蜗壳大厚板的窄间隙焊接时,使用了STT技术,STT技术为CCD图像传感器用于自动化 焊接提供了可能,使大型水轮机厚板的窄间隙焊接取得成功。
CCD image sensor used in the welding process, due to arc light to make their photosensitive cells are electrically saturated, affecting its accuracy and reliability of access to information, the filter can be used to reduce the interference of light. Surface tension transition technology has a low line energy, low spatter and high arc stability. Therefore, the STT technology is used in the narrow gap welding of the large volute large plate of the Three Gorges Project, and the STT technology has made it possible for the CCD image sensor to be used for the automatic welding, thus succeeding in the narrow gap welding of the large hydraulic turbine slab.
