Why Fabricators Rely on Robotic Welding
With Industry 4.0 and the digitalization of manufacturing, technology is revolutionizing every aspect of machine shops – and welding is no exception. Robotic welding has been integral to manufacturing for many years and offers fabricators numerous advantages over traditional manual welding. The key benefit of automated welding is the ability to rapidly produce high-quality welds, increasing fabrication efficiency and consistency as well as safety on the shop floor. Many industries employ robots for welding operations and some common forms of robotic welding include resistance, spot, arc, TIG, MIG, laser, and plasma welds.
Fabricators rely on robotic welding for heavy fabrications for the reasons noted below including higher quality, throughput and safety – all of which lead to a competitive edge for machine shops. State-of-the-art technologies, like robotic welding, make fabricators, like ABS, stand out from the competition. These shops deliver high-quality parts in less time – making for very happy customers. At ABS, our high level of production quality and repeatability enable us to deliver consistent products to customers – becoming their trusted fabrication partner for the long-term.
- Enhanced Precision and Quality: it is simply unrealistic to expect an operator to perform a job exactly the same every single time. Conversely, robots are designed to do just that: create excellent quality welds with incredible precision every time. Once programmed, robotic welding machines perform the exact job parameters and specifications - flawlessly. 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.
- Increased Throughput: fabricators rely on robotic welding for heavy fabrications because it saves considerable amounts of time. Robots are able to work 24 hours a day, 7 days a week with no fatigue or need for breaks except for occasional maintenance. Robots are designed to execute a specific job, typically a repetitive task, and are known for their efficiency on the shop floor. As a general rule of thumb, well-trained welding operators often perform around 50% arc-on time while robots are between 75-95% arc-on time. This increased productivity allows robotic welding to complete the job quicker. In addition, welding mistakes are avoided with robotic welding, eliminating the time spent on rework or refabrication of parts. For these reasons, 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 – streamlining fabrication and leading to a faster speed to market.
- Less Waste Generation: since robots produce more consistent welds with fewer errors, there is less rework required and lower waste generated during heavy fabrications – making robotic welding more cost effective than traditional manual methods. Robots use the precise amount of material required for a given job and are not tempted to “over-weld”. Robotic welding typically consumes less materials and creates less scrap and rework than manual welding – delivering a huge time and money savings for machines shops. Also, less waste generation with robotic welding results in an easier and quicker post-weld cleanup – providing additional efficiency gains. Additionally, the use of robots often saves energy as operators are not constantly starting up and shutting down welding equipment and machinery in between tasks.
- Improved Safety: welding operations during heavy fabrications often exceed temperatures of 6,500°F. Thus, it is no surprise that welding tasks present safety risks such as sparks, flash, fumes, and heat. The use of robotic welding machines removes operators from higher risk, hazardous processes, improving personnel safety. Robots are not impacted by most of these hazards and if they are damaged, robots can be repaired or replaced. A safer work environment reduces lost personnel time due to accidents on the job - leading to higher efficiency on the shop floor and, of course, a safer, happier workforce.
- Lower Labor Costs: machine shops around the world have experienced labor shortages in recent years especially highly skilled welders. Robotic welding machines are able to fill the labor gap in many cases, reducing the number of qualified personnel required for welding operations necessary for heavy fabrications - reducing the labor costs. Robots also enable a machine shop to scale production up or down more readily as market conditions and demand fluctuate over time.
