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

GMAW process. Gas metal arc welding, sometimes referred to by its subtypes metal inert gas and metal active gas is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal, which heats the workpiece metal, causing them to fuse. GMAW is a welding process which joins metals by heating the metals to their melting point with an electric arc and the arc is struck between a continuous, consumable bare (not covered) electrode wire and the work pie
