How is the "travel speed" defined in welding?

Travel speed in welding refers to the speed at which the welding torch or electrode moves along the joint being welded. This parameter is crucial as it directly influences the quality of the weld. If the travel speed is too fast, it can lead to inadequate penetration and weak welds, while too slow of a speed may result in excessive heat input, causing deformation or excessive weld bead height.

Understanding travel speed can help welders achieve optimal results, as the right speed ensures proper fusion of the base metals and the filler material. It also affects the appearance of the weld bead and the overall efficiency of the welding process. By controlling travel speed, welders can maintain the necessary heat input and cooling rates, which are integral to producing strong, durable welds.
