Collaborative Robots in Spot and Arc Welding Tasks

May 25, 2021

The central advantage offered by collaborative robots (cobots) is their capacity to work without an enclosure. The innate security features incorporated into these machines enable them to work alongside human laborers.

The subsequent logical step for cobots is to begin handling tasks previously handled by traditional robots. This includes sensitive tasks like welding. Mechanized welding is mainly sought after since many skilled workers are retiring and aren’t being replaced.

A rising number of producers are using the welding cobot to gain the required limit and versatility. In this review, we will look at the benefits of cobots in spot and arc welding operations and so much more.

The Benefits of Collaborative Robots in Spot and Arc Welding Include:

Cobots Are Quick and Easy to Teach

Cobots allow somebody acquainted with the welding cycle to guide them by physically moving the torch and arm through a programmed route to weld a piece. This simple-to-use feature enables producers to teach an employee who is new to robotics on how to handle a robot very quickly.

Cobots Are Safe to Be Around

While it’s true that cobots allow human laborers to work in close proximity to them, manufacturers need to take the required precautions.

There are hazards related to any welding, including arc flash, weld splash, piercing wires, and hot parts regardless of the cobot. Remember, cobot welding is safe if the proper precautions are taken when working alongside the cobot on the production line.

Consequently, PPE (personal protective equipment) and training are still needed as deemed necessary by health and safety measures in the workplace.

Cobots Are Easy to Move Around in The Production Floor Area

Unlike some more extensive and heavier welding robots that weigh around 200 kg, cobots weigh about 50 kg. They can be situated on a small forklift truck or a simple wheelbase. Cobots can be reinstalled somewhere else inside the factory since production needs vary.

The perfect use for a machine of this size would be a production line or factory that already has welding counters built for manual operators. The cobot could undoubtedly be brought in to help complement manual operators.

Cobots Are Ideal for High-Blend Low-Volume Production Tasks

Since these robots are simple to teach makes them ideal for high-blend, low-volume production tasks. Rather than spending an hour or more programming for a piece that requires maybe half the time, the operator programming the cobot may need just a few minutes to get the cobot up and running, enabling brief exchange times.

The use of mechanical welding for high-speed creation in low amounts likewise helps decrease process duration and keeping-up quality while potentially freeing up a human laborer to perform other tasks or complex welds more suited to a skilled manual welder.

With Cobots, You Can Achieve Lower-Cost Per Piece

If human laborers are diverted to other active tasks like custom welding, there is the chance to bring down the cost per unit. If the cobot is running concurrently as the trained welder is working on another task, there is a chance to reduce the cost-per-unit after achieving ROI.

Cobots Give You Longer and Continuous Weld Seams

The usage of welding cobots empowers the capacity to create a continuous weld crease. A trained welder can only weld a two-foot crease in a constant motion, whereas a collaborative robot can double that to weld a four-foot crease

This is useful with long fragments since you can only make a few starts and stops; this ensures the resultant weld is of high quality. Such a part would also require ample space to work on manually. Collaborative robots, on the other hand, need very minimal space

Final Thought

All in all, spot and arc welding activities can be implemented in a production line by human laborers. But as we have illustrated above, involving machines and, in this case, cobots ensure the weld is of better quality and at a reduced cost.
