Gas-shielded Metal Arc Welding (GMAW) is a welding type in which an arc is maintained between a continuous solid wire electrode and the work-piece. Using CAVILUX Laser Illumination enables you to identify details such as melt pool behavior, spatter, and the overall quality of the weld. Researchers are able to change any single variable in the process and can see visually the effect of the change during the process. This makes the research quicker and more precise, as well as backing up findings
