This presentation will provide an overview of modern implementation techniques and technologies for high-speed imaging of welding, including high-speed videography, high-speed thermography, and high-speed bifurcation temperature measurements. Applications covered will include arc welding (including SAW) and laser processes. Challenges to high-speed imaging of metal transfer in welding are the fast time constant of phenomena observed, and the intense light emissions that result in very high contrasts. While an effective tool for studying metal transfer, weld pool flows, and plasma arc properties, high speed videography techniques are often not optimized to the specific welding process, or the videography conditions are not well documented. The presentation will discuss light emissions from the arc and molten metal, considerations for the sensor types, filter, and video digital files, and the three main lighting techniques used: backlighting, front lighting, and natural radiation. The current implementation at the Canadian Center for Welding and Joining will be discussed in detail with examples.
