completed. In stainless steels, such as type 304, the crystal lattice is face-centered cubic(austenite). During high temperature welding, some surrounding metal may be elevated tobetween 500°F and 1000°F. In this temperature region, the austenite is transformed into a body-centered cub[r]

1. These control schemes all suffer from one, or more, problems in the real world where the relationship between the measured parameter and the amount of inhibitor needed is broken due to such things as leakage, cross ties (in leakage), thermal load changes, and changes in the m[r]

Continuous signals have been associated with smooth weld beads, while burst signals apparentlycorrelate with surface markings on nonuniform weld beads. Defect-related signals, especiallycracks, have been found to be of greater amplitude than the continuous AE signals (Fang et al.,1996; Jolly, 1969;[r]
