| Abstract Scope |
For many metal joining processes, welding process stability is vital for producing consistent weld quality. There are a variety of physical processes that can be observed with a HSV system, including metal droplet transfer and spatter generation. However, HSV must be correlated to the welding power source and process parameter data to identify the physical phenomena that produce desired process conditions. The addition of high speed synchronized DAQ to monitor wire feed speed (WFS), voltage, and current augments the analysis of welding processes to help quickly and efficiently identify physical process changes. At EWI, upgrades to an existing HSV and synchronized DAQ system have been used on a variety of welding transfer modes to analyze process stability. The results of the captures from the upgraded system have been used to analyze phenomena such as spatter generation, shielding conditions, and metal droplet transfer rate. The HSV and DAQ system was designed to be system agnostic – meaning that any type of welding transfer can be analyzed including laser and plasma arc welding. Conclusions from the work show that using HSV to analyze metal transfer at a low level can have large-scale impacts on process stability and ensuring high-integrity metal joining. |
