Welding

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld.

  • Welding and welded joints of the heat-resistant plastics

    Until recent time no scientific researches on weldability of new heat- resistant thermoplastics, known as polyarylenes, have been carried out in Ukraine.

  • A model-free adaptive control of welding pool dynamics during arc welding

    Arc welding process is characterized as nonlinear, time varying, and uncertain. So it is very difficult to design an effective control scheme by conventional modeling and control methods. Quality control of arc welding process is the key component in robotic welding system. This paper addresses model-free adaptive control with functional reinforce of Al alloy weld pool dynamics during pulsed gas tungsten arc welding (GTAW). This control method only needs the observed input output data and also has functional reinforce to improve the performance of the controller. The shape and size parameters for the weld pool are used to describe the weld pool geometry. The welding current is selected as the control variable, and the backside width of weld pool is selected as the controlled variable. To achieve the goal of full penetration and fine weld seam formation, a model-free adaptive controller with functional reinforce is designed for control of the maximum backside width. This controller of weld pool is independent on mathematic model. Numerical simulations confirmed that the developed control system is effective in achieving the desired fusion state.

  • Study on laser hybrid welding process monitoring

    In this paper, a study of process monitoring technology for the laser hybrid welding was conducted. The laser welding, arc welding and the industrial robotic systems were used with robot-based laser hybrid welding systems. The laser source, arc welding and robot systems are used to increase the processing speed and to improve the efficiency of welding processes. The robot-based laser hybrid welding system was equipped with a laser head and arc welding gun for laser hybrid welding. The welding joints of steel plate and aluminum plate were butt and Fillet joints. The quality testing of the laser hybrid welding was conducted by observing the shape of the beads on the plate and the cross-section of the welded parts, analyzing the results of mechanical tensile test, and monitoring the plasma intensity by using UV and IR sensor. This paper proposes the quality monitoring method and the robot-based laser hybrid welding system as a means of resolving the limited welding speed and accuracy of conventional laser welding systems.

  • A Low-Cost Welding Status Monitoring Framework for High-Power Disk Laser Welding (December 2018)

    Welding status determines the post-weld quality and is crucial to high-power disk laser welding. A low-cost monitoring system based on two photodiodes is developed to monitor the real-time welding statuses in this paper. A deep learning architecture based on stacked autoencoder (SAE) is proposed to automatically learn more representative features of welding statuses from the raw signal features captured by the visible light photodiode and the reflected laser light photodiode without any manual operations. The maximum correntropy loss function is applied to improve the learning ability of the proposed SAE method. Furthermore, a genetic algorithm is applied to optimize the key parameters of the proposed SAE method. The proposed SAE is applied to the high-power disk laser welding experiments and shows better performance in welding status monitoring than the standard AE framework and the conventional SVM and BP method. Additional experiments with different welding parameters validate the effectiveness and robustness of our proposed SAE method.
