Structural analysis of traditional Chinese hidden-keyhole padlocks [PDF]
Mechanical Sciences, 2018 Hidden-keyhole padlocks use a plate or some other means to cover the keyhole and are a category of traditional Chinese padlocks. The topological structures of traditional hidden-keyhole padlocks have distinct arrangements in the operation.

Depth Dependence and Keyhole Stability at Threshold, for Different Laser Welding Regimes [PDF]
Applied Sciences, 2020 Depending of the laser operating parameters, several characteristic regimes of laser welding can be observed. At low welding speeds, the aspect ratio of the keyhole can be rather large with a rather vertical cylindrical shape, whereas at high welding ...

Journal of Materials Research and Technology, 2020 Severe spattering is one of the common problems during fiber laser keyhole welding. In this study, the correlation between the spatter formation and laser-induced evaporation vapor on the front keyhole wall (FKW) was studied by changing the welding speed
