Critical to the success of many robotic applications, is the ability to give “sight” to the industrial robot being used. For welding tasks, traceability and inspection have become extremely important for fabricators looking to improve weld quality and product throughput.

Depending on the type of welding being completed, a very successful approach for achieving this is through the use of intelligent vision systems. Whether a process involves arc welding, laser welding, laser brazing or another hybrid option, 3D laser vision systems can assist in many industries to perform 3D joint tracking, robotic inspection, process control and more.

Why Laser Weld Inspection

With the majority of weld inspection still performed by human workers, the margin for error can be significant. 2D or 3D laser vision systems help to mitigate this by being:

More Consistent

Performing and documenting of measurements by hand is subjective and inconsistent, and it can vary from inspector to inspector. This also usually relies on a smaller sample of parts produced due to the time it takes to inspect each part.

Broader in Scope

While there are dozens of gauge sets and different methods of geometry available for use, they can limit the weld inspection process. Certain dimensions can be difficult to measure, and entire welds may not be measured continuously.


Even skilled engineers can only move so fast. Measuring and documenting values occupies skilled engineers for extended periods of time, utilizing valuable resources that could be used elsewhere for more value-added tasks.
