The purpose of this paper is to review the challenges facing manufacturers and metal fabricators attempting to automate the welding of materials with irregular, inconsistent or difficult to access joint interfaces; and established technology and recent advancements that have made robotic automation in this segment far more viable.
In principle the addition of sensors to robotic equipment will enable the automation technology to operate with remarkably human-like capabilities. When a sensor system is correctly selected, installed and trained (programmed) it will significantly extend the operational capability of the robotic arm and controller combination. In robotic welding systems the introduction of sensors provides the adaptive capability of touch and sight to address the challenges of a “moving” weld seam or component.
