Arc welding utilizes an electric arc between an electrode and a metal base using either consumable or non-consumable electrodes. An arc welding robot uses a process which applies intense heat to metal at a joint, causing the metal to melt and intermix.
Robotic arc welders are more consistent throughout the weld and provide repeatability, providing higher quality welds. Robots can also save workers from health hazards by limiting exposure to fumes and decreasing risk of arc burn.
