采用焊接电弧光谱检测装置,对脉冲MIG焊熔滴过渡的光谱信息进行了研究,结果表明,电弧光谱信息可以很好地反映脉冲MIG焊的熔滴过渡;发现了多种熔滴过渡的光谱信息模式,这些模式可反映1峰0基、1峰1基等各种形式的熔滴过渡,特别是可以对脉冲峰值期间的多滴喷射过渡作出清晰的反映;信号波形的脉动幅值大,脉宽较宽,抗干扰能力强,容易识别,信号品质优越。这些结果为脉冲MIG焊熔滴过渡的光谱实时控制奠定了良好基础,为脉冲MIG焊的控制开辟了一条新途径。

本文开发了集辅助激光成像系统、紫外/可见波段视觉成像系统(波长小于780 nm)、光谱测量仪、光电传感器的多传感器系统,用以观察和分析激光焊接过程中的焊接状态信息。本文采用小波包分解方法对通过光电传感器获得的可见光波段传感信号和激光反射传感信号进行分解并提取相关特征。光谱仪采集到的信号的主要波长为400~900 nm,将其分为25个子带并采用统计方法来提取光谱信号特征。利用紫外/可见波段视觉成像系统采集的图像获取金属蒸气和飞溅的特征,而辅助照明视觉传感器系统主要是用来采集匙孔特征。本文基于上述焊接过程的实时量化特征建立了焊接状态监测的深度信念网络(DBN),并采用遗传算法对所提出的DBN模型参数进行优化。与传统的反向传播神经网络(BPNN)模型相比,本文建立的DBN模型在焊接状态监测方面具有更高的精度和鲁棒性。最后,本文通过三个附加焊接试验验证了该方法在激光焊接状态监控中的有效性和泛化能力。

This paper focuses on the two-robot welding coordination of complex curve seam which means one robot grasp the workpiece, the other hold the torch, the two robots work on the same workpiece simultaneously. This paper builds the dual-robot coordinate system at the beginning, and three point calibration method of two robots’ relative base coordinate system is presented. After that, the non master/slave scheme is chosen for the motion planning, the non master/slave scheme sets the poses versus time function of the point u on the workpiece, and calculates the two robot end effecter trajectories through the constrained relationship matrix automatically. Moreover, downhand welding is employed which can guarantee the torch and the seam keep in good contact condition all the time during the welding. Finally, a Solidworks-SimMechanics simulation platform is established, and a simulation of curved steel pipe welding is conducted. The results of the simulation illustrate the welding process can meet the requirements of downhand welding, the joint displacement curves are smooth and continuous and no joint velocities are out of working scope.

Review on electromagnetic welding of dissimilar materials

Electromagnetic welding (EMW) is a high-speed joining technique that is used to join similar or dissimilar metals, as well as metals to non-metals. This technique uses electromagnetic force to mainly join conductive materials. Unlike conventional joining processes, the weld interface does not melt, thus keeping the material properties intact. Extremely high velocity and strain rate involved in the process facilitate extending the EMW technique for joining several materials. In this paper, the research and progress in electromagnetic welding are reviewed from various perspectives to provide a basis for further research.
