Real-time monitoring of laser beam welding using infrared weld emissions
Journal of Laser Applications, 1998A nonintrusive, solid-state device has been developed to monitor in real time the infrared emissions during laser welding. The weld monitor output is an analog signal (100–1000 mV) that depends on the beam power and weld characteristics. The dc level of this signal is related to weld penetration, while ac portions of the output can be correlated with ...

Real-time estimation of weld penetration using weld pool surface based calibration
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016Appropriate depth of weld penetration is required in many precision joining application but the weld penetration underneath the work-piece is not directly/conventionally measurable during the welding process. This work aims at establishing an analytic model to correlate the measurable weld pool surface to the development of the weld pool.

Effect of Welding Time in the Resistance Spot Welded Dissimilar Stainless Steels
Transactions of the Indian Institute of Metals, 2014In this study, the effect of welding time on joining capability of austenitic stainless steel (AISI 304) sheets and ferritic stainless steel (AISI 430) sheets by using resistance spot welding (RSW) process was investigated. Therefore, macrostructure, microstructure, microhardness, tensile shear strength, and failure mode of welded materials were ...

Real-time laser weld point seam tracking system for robotic welding
Journal of Computer & Electrical and Electronics Engineering SciencesThis paper presents a real-time vision-based laser weld seam tracking system optimized for robotic welding. The core innovation is a computer vision algorithm that processes video data to detect welding points with high precision, achieving an average absolute error of ±0.23 mm, with varying precision for different joint types (butt joint: ±0.63 mm ...
