DOI: 10.1016/j.measurement.2020.107966

Abstract: Abstract This paper presents a novel methodology for welding penetration recognition in Keyhole Tungsten Inert Gas(K-TIG) welding. A multisensor sensing system is established to acquire the signal of arc sound, arc current, and arc voltage.… read more here.

DOI: 10.1109/tii.2025.3582401

Abstract: Welding defects recognition based on arc sound signals remains a significant challenge in robot arc welding. Existing deep learning methods mainly focus on classifying penetration states rather than recognizing multiclass defects, such as slag inclusion… read more here.

DOI: 10.1177/0954409718799792

Abstract: In recent years, the speed and the current transmission density of high-speed railways are increased. As a result, the rate of the occurrence of pantograph–catenary arc also increases, which directly influences the service performance of… read more here.

DOI: 10.1371/journal.pone.0311119

Abstract: Arc sound signals are considered appropriate for detecting penetration states in cold metal transfer (CMT) welding because of their noninvasive nature and immunity to interference from splatter and arc light. Nevertheless, the stability of arc… read more here.

DOI: 10.3390/app13085152

Abstract: The cold metal transfer (CMT) process is widely used in thin plate welding because of its characteristics of low heat input and stable arc. In actual production, a larger weld gap, misalignment, or other problems… read more here.
