Knowledge distillation is an attractive approach for learning compact deep neural networks, which learns a lightweight student model by distilling knowledge from complex teacher model. Attention-based specific form of intermediate feature-based that uses attention mechanisms to encourage the better mimic teacher. However, most previous attention-based approaches perform in spatial domain, primarily affects local regions input image. This may not be sufficient when we need capture broader...
In this study, the effect of oxygen in shielding gas on material flow behavior weld pool surface was discussed to clarify dominant driving force keyhole plasma arc welding (KPAW). To address issue, convection top observed using a high-speed video camera. The temperature distribution along wall measured two-color pyrometry method confirm Marangoni activity pool. results show that inclination angle (keyhole shape) increased especially near due decrease tension through oxidation when Ar + 0.5%...
Nonwoven fabrics are widely used in the textile manufacturing industry due to their advanced characteristics, such as soft, water-repellent, recycle, ecological, and resilient functions. Nowadays, one of innovated technologies applied bond nonwoven is ultrasonic welding method, advantages afforded by its clean, fast, reliable approach. In this work, isotactic polypropylene (PP) were bonded a continuous process. order consider influence roller on formation joints mechanical properties,...
This investigation aims to develop a new Plasma-MIG hybrid welding process for butting joints of large thickness. In this process, Plasma torch and MIG are connected in electrode negative (EN) positive (EP), respectively. is set up the leading position, meanwhile trailing position. The plasma utilized keyhole model. results show that successful single-sided one pass fully penetrated. wettability improved penetration increased comparison with only conventional process. addition, order discuss...
This paper aims to develop a novel tungsten inner gas (TIG) welding torch in order join thin sheets efficiently. Using narrowing nozzle (constricted nozzle) inside conventional TIG can critically improve the position accuracy of electrode and also arc plasma characteristics heat input density. In evaluate efficiency this new torch, weld bead appearance cross-section images were examined by an optical microscope, scanning electron microscope (SEM), back scatter diffraction patterns (EBSD)....
Abstract This work investigates the application of ultrasonic vibration to steel joints formed by gas metal arc welding. Welding is done using a active welding source with current 120–160 A, 0.8 mm diameter wire and 10 l min −1 CO 2 flow. The distance from torch horn 120 mm. Ultrasonic most affects weld when position increases penetration speed 190 (275) mm/min for 5 thick (10 thick) plate. Moreover, width Although does not affect hardness zones, it modifies microstructure diffusion...
This investigation is purposed to clarify the influence of pilot gas composition convective pattern on weld pool surface in Plasma keyhole arc welding process. In order this, top was investigated both cases gas: pure Ar and mixture with 10% hydrogen. For estimating pattern, zirconia particles diameter 0.03 mm were utilized as tracers. After welding, using software (Dipp-motion, Detect Co., Ltd) for analyzing movement particles, estimated. case Ar, circulated motions just behind pool,...
The material flow dynamic and velocity distribution on the melted domain surface play a crucial role joint quality formation of welding defects. In this study, authors investigated effects low high currents plasma arc thermodynamics molten pool its relationship to high-speed video camera (HSVC) was used observe convection welded-joint appearance. Furthermore, consider Marangoni force activation, temperature measured by thermal HSVC. results revealed that weld higher than inside pool....
This paper aims to investigate the fabrication of high strength low alloy (HSLA) steels by wire and arc-based directed energy deposition (WADED). Firstly, relationship between process variables (including travel speed-V, current-C, voltage-U) geometrical characteristics weld beads bead height (BH), width (BW), melting pool length (MPL)) was investigated. Secondly, optimal were identified using desirability approach. The results indicate that voltage-U has highest impact on BW MPL, meanwhile...
