Measurements
1. Toe angles - angle between the weld and the adjacent plate at the left and right edges of the weld.
2. Face width - width of the weld between the two edges.
3. Plate angle - angle between the two plates.
4. Leg lengths - length of the plate from the edge of the weld to the projected intersection with the other plate.
5. Undercut - depth at the edge of the weld relative to the face of the weld.

Industry Examples
1. Steel - construction inspection on bridges and buildings.
2. Heavy Equipment - verification of specifications.
3. Shipbuilding - inspection.
4. Pressure vessels - quality control measurements.

Sensors and Controllers
The width of the weld will determine the sensor field-of-view required.  Typically an HS300 sensor with wheeled stand-off's and a Series 1100 controller will be used in portable inspection applications.  The stand-off's are designed so they roll between the angled plates keeping the sensor positioned over the weld.  For on-line applications, the Series 3000 controller and RS400 sensor could be used.
