Video: Key tips for defect-free laser welding on galvanized steel

---

In this video, we show how to properly weld galvanized steel using the MS20 laser welder. The main challenge is zinc, which evaporates at 907 °C, causing micro-explosions, spatter, and irregular weld seams. Compared to MIG or TIG, laser welding offers lower heat input, higher speed, and minimal distortion. We share the right parameters and key tips to achieve clean, stable, and controlled welds.
