Cobot for welding: a full guide to get started

Welding is one of the most complex and dangerous industrial applications. Welders must know how to fuse parts properly while avoiding the risks of burns and splashes.

So no wonder that automation solutions have quickly become a must-have for welding manufacturers. Collaborative robots have especially stood out on this task with their compact design and high flexibility.

But which cobot to choose and with which welding tool? And how do you integrate them into your existing application and workforce?

Here we give you our complete guide to getting started in the collaborative automation of your welding process.

Why use cobots for welding?

Of all the industrial tasks, welding is certainly one of the most dangerous. A worker who welds parts exposes himself to risks such as burns, splashes, cuts, and electrocution.

For this reason, historical robot manufacturers such as Fanuc or Yaskawa started early on to create robots specialized in welding. Their models have since proven to be successful in partially or fully automating these processes in large industries.

However, these industrial welding robots are not without flaws. They often cannot handle small parts, are difficult to move or repair, and require a large volume of welding to be profitable.

Collaborative robots overcome these limitations with their lightweight design, flexibility, and intelligence. Workers can quickly teach cobots specific welding applications, have them work on more detailed parts, and redeploy them to other workshops.

While these cobots don’t necessarily outperform standard robots on high volumes, they demonstrate high accuracy and quality of work. With cobots, manufacturers can reduce their production costs and allow their professional welders to focus on higher-value parts.

For all these reasons, a welding cobot might interest you if :

  • You’re struggling to hire experienced welders.
  • You want to optimize the cost and quality of your high mix, low volume welding process.
  • You want to reduce your welders’ risk on the shop floor or help them focus on high-value parts.
