Although there are many types of collaborative robots, the broader category of cobots is defined by certain characteristics—namely, the ability to work alongside human operators. To facilitate this function, cobots have advanced capabilities in terms of collision detection and automatically safe stop when they come into physical contact with a human worker. This differs from traditional industrial robots because a system of light curtains, walls, cages, laser scanners, and safety interlocks must be employed so to eliminate the risk of injury to the operator. While industrial robots are typically tailored for higher production, they also take up more floor space and take longer to engineer and setup.
This is a tricky question because a robot may not perform a task faster than a person, but a robot can perform a task more consistently than a person, and it does not fatigue. Also, welding is limited by the physics of the welding process, but a person with little or no welding skills can keep a robot in production once the robot has been set up correctly.
Typically, robots do not take away jobs. What usually happens is this. A company will choose the highest production parts and put them on a robot. This allows the welding staff to produce more low volume or more complex components because the robots are handling the high production parts. Robotic MIG welding can weld components that would normally be produced with the TIG process. Because the MIG process is much faster than TIG, more production can be performed with the same floor space, allowing for more productive.
Once you plug the system in and power it up, striking your first arc all depends on the complexity of the part. With the Universal Robots UR10e and THG Automation's tight integration with Fronius, you could be welding parts in as little as a day. Fronius makes it relatively easy to set up their weld jobs with their Weld Wizard.
Many parts can be welding on one robot and also parts of different base materials. One day you can weld steel parts, the next day you can weld aluminum parts on the same system. It takes three basic conditions to weld a part or assembly. The first is the tooling. Holding the part in the same place every time is very important. The tooling can be a couple of angles clamped to the table or engineered tooling for more complex holding. The second condition is the weld jobs. Fronius TPS 400i power sources can store up to 1000 jobs. More than enough to keep all your carbon steel, stainless steel, and aluminum settings in one power source. Third, the robot programs. Many programs can be stored in the Universal Robots controller. With today's robot controllers, there is usually more than enough memory space to handle all your needs.
