Development of Hot-wire Laser Welding Method for Lap Joint of Steel Sheet with Wide Gap

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2011
In this study, hot-wire laser welding was used to develop the welding method for the lap joint of 980MPa class high-strength steel sheets (thickness: 1 mm) with a wide gap. Detailed phenomena of wire melting and bead formation during welding were understood using the high-speed camera, and then the optimum welding condition and the mechanical ...

High-Power and High-Brightness Laser Butt Welding with Using Hot Wire for Thick High-Strength Steel Plate

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2011
High-power and high-brightness lasers such as fiber laser or disk laser are promising as desirable heat sources for deeply-penetrated welds, owing to their superior power density. However, their tightly-focused beam spots have low gap tolerance in butt welding.

Development of automation and monitoring methods for narrow-gap hot-wire laser welding using camera images

Welding in the World
AbstractIn this study, an image-based method was developed for hot-wire laser narrow gap welding. The welding process was monitored based on image information processed using semantic segmentation, a method of classifying images by pixel. To control the welding position, an experimental system was configured that automatically follows the welding ...
