What does the term "stringer beads" refer to in GTAW?

The term "stringer beads" in Gas Tungsten Arc Welding (GTAW) refers to a welding technique where the filler metal is added as a thin line along the weld. This technique is characterized by its simplicity and is typically used for flat welds. Stringer beads involve moving the welding torch in a straightforward, continuous motion, allowing for a narrow bead to be formed with the filler metal introduced directly into the weld pool without excessive manipulation or weaving.

This method is advantageous in maintaining a narrower heat-affected zone and promoting faster welding speeds. In contrast to other techniques that may employ weaving or oscillation, the stringer bead approach helps in controlling the weld profile more effectively, making it ideal for applications that require precision and a clean finish.
