Robots are designed to execute a specific job, typically a repetitive task, and are known for their efficiency on the shop floor. Robots are able to work 24 hours a day, 7 days a week with no breaks except for occasional maintenance. For this reason, robots are capable of higher welding productivity and throughput. Higher volumes and faster cycle times translate to lower costs that provide a critical competitive edge to manufacturers. Additionally, multi-axis robots or robots fitted with slender arms are able to reach difficult welding locations that are common on heavy fabrications due to their large size and unique geometry. Employing robots speeds up the manufacturing process, reduces costs, and enables more throughput – maximizing efficiency and leading to faster speed to market.
Automation delivers superior precision, which is another way robotic welding maximizes efficiency. Heavy fabrications are often very large with intricate geometries, and some of these parts undergo significant stress. For these reasons, the welds must be consistent and precise, and free of voids and contaminants, in order to ensure stability and longevity of the part. Human welding can often introduce variance and inconsistencies, whereas, robotic welding machines are known for their excellent precision and quality. Many heavy fabrications require high precision and alignment of parts that are challenging – if not impossible - to achieve with manual welding. Since robots produce more consistent, efficient welds with fewer errors, they drive production consistency – leading to fewer rejected parts and maximum efficiency.
