In gas metal arc welding, like other welding techniques, the quality of welded joint may be described in terms of weld bead geometry and the presence of welding defects. In turn, the characteristics of welding signals, ...

approach is based on the features of welding electrical and sound output signals. The weld

quality characteristics are defined in terms of weld defects (discontinuity, lack of fusion and overlap) as well as weld shape factor. These measures...
