Paper presented at the The Ninth International Offshore and Polar Engineering Conference, May 30–June 4, 1999
Paper Number: ISOPE-I-99-370
... camera and a penetration control system using Neural Network in TIG arc welding are investigate. In order to characterize the shape of molten pool, width, length and area of the molten pool were measured, and are used to form the contour of the molten pool as a shape parameters. These parameters...
