Science, Technology & Engineering on Instagram: "This video showcases a handheld laser welding gun, a component of a fiber laser welding machine. The device uses a highly focused beam of light to join metal parts with incredible precision and efficiency. Laser welding is much faster than traditional welding methods — often 2-10 times quicker — and produces minimal deformation or welding scars, reducing the need for extra finishing work. The video highlights the clean, precise, and almost futuris

The jobs we'll lose to machines -- and the ones we won't
