As vehicles are assembled, the fit-up of various parts is inspected by measuring the width of the gap between two adjacent panels and the alignment of the two surfaces, also called flushness.

Application Brochure

Fasteners on the exterior of aircraft must be flush to the surface within a certain tolerance.  A fastener that protrudes above or one that is driven below the adjacent surface may adversely affect performance in flight. 

 Application Brochure 

Automotive sheet metal parts must be stamped to exact dimensions for a vehicle to assemble properly.  A radius stamped into the part and the location of the radius relative the part's edge can be measured using a specialized LG sensor.

Application Brochure 

Potential weaknesses in a weld can be revealed in the evaluation of its surface characteristics.  The height, width, and area of a butt weld are factors in its strength.

 Application Brochure

Residential siding board has a wavy pattern on the front side.  The production process must insure that the contour of those waves consistently stays within a range.  If the profile of the boards is not consistent, they will appear to be different colors when installed on the side of house and the consumer will not accept this patterned look.

 Application Brochure 

The leading edge of a vane or blade used in aircraft or power system engines must maintain its designed contour within an acceptable range for safe and efficient operation of the engine.  Measurements that are critical include the edge radius and the width or thickness of the blade at varying distances away from the edge.

Application Brochure

Sheet metal coils of different thickness are laser-welded together and cut into blanks.  The blanks are used in stamping certain automotive parts.  Using blanks that have variable thickness saves the cost and weight of the unneeded metal.  Since the metal is subjected to a stamping process, the integrity of the weld is critical.

 Application Brochure

Critical components in aircraft and space vehicles can be damaged by foreign objects during repair processes or by unexpected wear during normal operation.  Any material removed from a surface by a scratch or a gouge or any deformity of a surface, such as a dent, may compromise the safety of the vehicle.

 Application Brochure

Pitting on a jet engine turbine blade requires repair once it exceeds a depth threshold.  If the pitting is too severe, the blade cannot be repaired and has to be scrapped.  Identifying blades that are eligible for repair saves significant costs for the airlines.
