Welding has long been a key technology for assembling metals parts in various industries. Nowadays with the constant search of quality and productivity, welding has become increasingly sophisticated with the introduction of new processes and the automation of these processes. It is essential to visualize and monitor, in great details and as closest as possible, the weld pool (melt metal) during and/or after the process for ensuring quality, consistency, and reproducibility of assembly. This is a particularly difficult task when considering the high temperature, high level and fast variation of light intensity, and high contrast generated during these operations.
