Measurements
1. Crown height - maximum height of the weld relative to the line drawn between the two weld edges.
2. Weld width - width of the weld between the two edges at the base.
3. Mismatch - height difference of the projected parent surfaces at weld center.
4. Peaking - angle difference of the projected parent surfaces at weld center.
5. Undercut - depth of any undercut relative to the line drawn between the two weld edges.

Industry Examples
1. Space - inspection of welds on external tanks.
2. Welded Steel Blanks - verification of compliance with customer specifications.
3. Shipbuilding - quality inspections.
4. Pressure Vessels - measurement of weld features.

Sensors and Controllers
Sensor selection will be dependent on the size of the weld.  For very small welds such as laser welded blanks, the HS400 which has a narrow field-of-view and higher resolution would be used.  Any of the sensors and controllers could be used for the application including the Series 3000 controller with the RS400 sensor for on-line inspections.
