At first glance, a robotic arm and a torch may look like everything needed to automate the welding process. However, in order to ensure maximum productivity, one must look at the system as a whole. This is the only way to optimize the performance of the equipment and ensure the safety of workers.
In this way, a welding robot must combine the following elements:
Robotic arm: sturdy and stable device, built in arm shape. This arm can move on different axes, which gives it great flexibility.
Welding torch: element placed at the end of the robot that serves as the delivery vehicle of the welding wire. Accompanying the torch there is a cleaning system (usually placed near the robotic arm) to clean the traces of welding, preventing them from solidifying in the torch.
Welding equipment: generator of the energy needed to create the welding arc (melt the wire).
Controller (HMI): works with the robot's brain. This controller allows adjustments or program changes to be made on site, increasing system productivity.
In addition to the components listed above, they should also be part of the system:
Safety devices: since one of the main reasons for using welding robots is to make workplaces safer for employees, robotic systems should include safety mechanisms such as safety curtains, sensors, metal guards, among others.
Jigs: are the tools to position the parts at the welding site. The tool design should allow for quick change of parts. Large parts may require other types of components such as gantries or lathes.
Many other components can be added to the systems, such as conveyor belts, loading and unloading tables, inspection equipment or others, depending on the level of automation we’re looking for and the value we’re willing to invest.
