The specter of robots taking well-paying manufacturing jobs from humans has long triggered a hostile reaction toward the steady march of automation in industry. There is no denying that robots have revolutionized industries such as auto manufacturing, and that jobs have been lost as a consequence. But is it all bad news? Will robots eventually make welders obsolete? This week at American Welding Online, we look at some of the predominant myths about robots and their role in industry.
1. A robot is going to steal my job:
Robotic welding and automated operations are being used as a supplement, not a replacement, for the workforce. As the skills gap worsens, companies are relying on robots to fill holes in the workforce for which these companies can’t find humans with the necessary skills.
2. I can’t afford a robot:
Automated welding can be expensive, but the cost is usually justified by better labor rates, increased productivity, increased volume, less variability and reduced costs in filler metal and training. Moreover, the actual cost of automated welding equipment has decreased over the years.
3. Robots are too complicated to learn:
Automated welding has actually come a long way, and is much easier to learn than it once was. Workers with limited welding experience can be quickly trained to operate robotic welding cells, because a significant amount of the skill required for manual welding is handled by the robot.
4. My operation is too small for automated welding:
Over the years, the programming of robotic welders has become much more flexible. Finely tuned digital communication between the robots components has made it possible to create automated systems that are economically justifiable and productive for manufacturing operations of almost any size.
5. It’s too difficult to incorporate automation:
There are a number of reengineered and customizable robotic cells that can be easily incorporated into your production line. You just need to find the right option for you. The only real limit on integrating automation is cleaning up your current process. You’ll need to eliminate any problems with parts variation and fitup, and the joints that the robot will weld should be easily reached by the robot’s arm. Besides these issues, however, automation is surprisingly easy to add to your production line.
6. Let’s weld everything with a robot:
Welding robots are a great way to improve production efficiency if your business can allow for it, but that doesn’t mean every task should be automated. Outdoor manufacturing operations, welds that robots simply can’t reach, and space constrained welds are just some of the tasks that emphasize the continued importance of semiautomatic and manual welding processes.
Despite our oscillating anxiety over an impending technological tyranny and our hopes for a world saved by science, it’s plain to see that automation is neither a malicious force come to rob welders of their livelihood, nor a cure-all for manufacturing production problems. It’s a tool, like any other equipment or process on the shop floor.
