Using laser welding for making tube or pipe on a mill is a proven technology, but and advancements in tracking systems and controls have made lasers easier to use than when they were first introduced. However, this doesn’t mean that swapping gas tungsten arc welding (GTAW) or plasma welding for laser is simple. Thinking about changing over to laser requires an understanding of how the laser welding process differs from GTAW and plasma welding, and how the various lasers differ from each other.
