A system is presented that allows the visualization of the whole welding process. Factors that can lead to bad welds can be monitored. Methods to optimize the welding process are outlined and a possible "on-line control" is discussed. In addition, schemes are presented for the analysis of the welding process to identify defects in the welding equipment that will cause faulty welds.

To achieve reliable welds with minimum distortion for the fabrication of components in aerospace industry laser beam welding is attempted. Laser welding can provide a significant benefit for the welding of Titanium and Aluminium thin sheet alloys of its precision and rapid processing capability. For laser welding, pulse shape, energy, duration, repetition rate and peak power are the most import...

Welding apprentices invest in their professional and technological education. The welding work, and before that, the welding apprenticeship, exposes the apprentices to several risk factors, such as a physical, chemical and physiological. Exposure to these factors can trigger various health disorders and accidents. Among some of the health disorders that may be triggered by welding activity are ...

Resistance spot welding is an important and widely used method for joining metal objects. In this paper, various classification methods for identifying welding processes are evaluated. Using process identification, a similar process for a new welding experiment can be found among the previously run processes, and the process parameters leading to high-quality welding joints can be applied. With...

OBJECTIVES Ultraviolet radiation (UVR) emitted during arc welding frequently causes keratoconjunctivitis and erythema in the workplace. The degree of hazard from UVR exposure depends on the welding method and conditions. Therefore, it is important to identify the UVR levels present under various conditions. METHODS We experimentally evaluated the UVR levels emitted in gas metal arc welding (G...

During machine learning algorithms, deep refers to a neural network containing multiple hidden layers. Welding research based upon has been increasing due advances in algorithms and computer hardwares. Among the convolutional (CNN) recently received spotlight for performing classification or regression on image input. CNNs enables end-to-end without feature extraction in-situ estimation of proc...
