Real-Time Weld Process Monitoring

Advanced Materials Research, 2014
Welding defects result infailure of the machinery and other negative consequences. Therefore, they need to be detected as they appear to ensure efficient and high-quality production. There is a raising interest in the implementation of sensors to provide highly accurate and robust real-time welding process monitoring.

Laser spot welding and real time evaluation

IEEE Journal of Quantum Electronics, 1975
The high-repetition-rate pulsed-YAG-laser welding of insulated copper wires to terminal posts and their real-time evaluation with stress-wave emission (SWE) are discussed. It is shown that to minimize damage to the wire from the incident radiation a shoulder terminal, wherein the shoulder covers the wire, is desirable.

Real-time ultrasonic weld inspection method

The Journal of the Acoustical Society of America, 1985
The ultrasonic weld inspection method comprises transmitting an ultrasonic wave through the molten metal portion of the weld while the weld is being formed and determining if a weld defect is present in the molten metal. If no defect is detected in the molten metal, the welding process continues.

Real time weld quality monitoring of laser welded blanks – Weld profile monitoring

ICALEO '99: Proceedings of the Laser Materials Processing Conference, 1999
It has been found that the geometry of weld cross-sections influences the formability of tailor welded blanks significantly. The primary defects associated with most weld failures during stamping are top concavities and convexities, root concavities, lack of fusion, pinholes, and porosity. Most weld quality monitoring devices, such as plasma monitoring

Real-time imaging for arc welding

International Journal of Computer Integrated Manufacturing, 1990
Abstract ESPRIT (CIM) Project 9 has taken automated welding systems as instances of 'machines' for which have been developed local, intelligent, corrective systems. Two widely different systems have been studied: single-pass welding, representative of the thin-sheet/high-volume industry (e.g.

INFLUENCE OF WELDING TIME ON MECHANICAL FRICTION WELDING OF BEECH

2021
The optimum welding time for welded beech specimens is assessed with a compression shear test method and the softening of the wood polymers during friction welding is evaluated by dynamic mechanical analysis (DMA). A welding time of 2-3 sec yields the highest mechanical performance (13.6-14.7 MPa) that is equivalent to the shear strength of glued ...

SIMULATION SLASHES WELD LINE DESIGN TIME

Industrial Robot: An International Journal, 1991
Most of the business of Koltanbar Engineering is designing large automated welding lines producing body assemblies. In the past, designing a welding station for one of these lines was an extremely time‐consuming process requiring complicated sectional drawings at each welding point, which were stacked up to determine the gun configuration; intricate ...

Wood welding: Chemical and physical changes according to the welding time

2008
Wood welding using linear friction is a technique that has been developed in the past five years. The goal of this study was to analyze the microstructure development in the interphase enabling the wood-to-wood adhesion without any adhesive. Chemical and physical analyses have been carried out using infrared ther- mography, mechanical shear tests ...

Real-time control of laser-hybrid welding using weld quality attributes

ICALEO 2004: 23rd International Congress on Laser Materials Processing and Laser Microfabrication, 2004
Applied Thermal Sciences, Inc is developing and validating an automated, large-scale laser GMAW-assisted welding process that can be utilized to fabricate high-precision lightweight structural shapes for shipbuilding and other industries. At the heart of this laser welding process is a real-time, adaptive Process Control System (PCS).
