A time-dependent measuring system for welding deformation 总被引:2,自引:0,他引:2
In this paper the establishment and application of a time-dependem measuring system for welding deformation are presented which is established with high quality sensors shielded from strong welding interferetwe. By using this system,vertical and horizontal displacements of the high temperature area are surveyed at the same time. And this system is also used for monitoring and controlling the deformation of real welded suttctures. 相似文献

以采集的电阻点焊接头表面的数字图像作为信息源,探索了一种新的点焊质量无损监测方法.首先,通过图像特征分析,焊点表面图像被划分为4个环形特征区域,提取环形特征区域面积作为表征焊点质量的特征参数.其次,根据特征区域面积与焊点抗剪强度的相关性分析结果,选择了相关性显著的3个特征参数作为输入向量,焊点抗剪强度作为输出向量,建立了点焊质量的RBF神经网络监测模型.仿真分析和验证结果表明,基于焊点表面图像特征信息处理监测点焊质量的方法是可行的. 相似文献

The paper describes a monitoring and control platform development for arc welding processes, which provides versatility and efficiency in the scientific study of the welding technology. The implemented system is capable of executing different welding processes and promotes substantial logical operation changes in a simple and didactic way. Among the innovations promoted by the development of the system is the ability to draw MIG/MAG welding process current waveforms, thereby allowing studies related to metal transfer, and, as a consequence of this, making technological innovations to this process. The monitoring and control platform has been developed to be able to absorb new technologies, allowing upgrades along the welding process evolution path. In this context, this system is a significant potential alternative to studies related to welding, in educational and research institutions within and outside the country. 相似文献
