Welding from every angle 💥📐 Welding is a physically demanding job, and sometimes, you need to bend (😩) and stretch (🥵) yourself out of shape in order to make the perfect weld. At Smallaire, they fortunately have a Cobot Welder from Hirebotics to do some of their welding for them, potentially saving them from unnecessary back pain. Look at how the robot is able to handle every weld from one spot 🤩 #robotics #automation #welding | Universal Robots
