Welding is a method of realizing material connections, and the development of modern
sensing technology is pushing this traditional process towards automation and intelligence …

As a traditional fusion welding method, arc welding occupies most of the total welding
production. However, the current industrial welding robots with the “teaching and playback” …

The reliability and accuracy of welding image recognition (WIR) is critical, which can largely
improve domain experts' insight of the welding system. To ensure its performance, deep …

Welding is a major manufacturing process that joins two or more pieces of materials together
through heating/mixing them, with or without pressure, as they cool and solidify. The goal of …

Penetration recognition is the critical technology to improve manufacturing quality and
automation level in arc welding. In this paper, recent research advances concerning …

Automatic welding penetration recognition is a significant and challenging research
direction to improve the manufacturing quality and intelligence level of gas tungsten arc …

During the welding process, the molten metal continuously solidifies along the trailing edge
of the molten pool to form the weld seam, so the change in the weld surface morphology can …

Most of the existing laser welding quality identification methods are post-weld identification
or low-speed identification (Welding speed below 120 m/min). Efficiently online monitoring …

Weld quality is generally determined by reinforcement and penetration depth of weld bead
in arc welding. Penetration depth reflects weld strength and reinforcement reflects weld …

High-power fiber laser welding has a broad range of applications in industrial processing
and modern intelligent manufacturing, but how to assess the quality of laser welding has …
