What is one common sign of poor weld quality?

One common sign of poor weld quality is excessive spatter or an irregular bead. When spatter occurs, it indicates that there may have been improper welding techniques or settings, such as inconsistent voltage or travel speed, which can lead to ineffective fusion or a weak joint. An irregular bead suggests a lack of control during the welding process, affecting the aesthetic appearance and structural integrity of the weld. Poorly executed welds can introduce flaws that compromise the strength and durability of the weldment, making this a vital indicator for welders and inspectors to consider.

In contrast, a uniform bead width and consistent penetration depth are signs of good welding practices, demonstrating proper control and technique. Additionally, a minimal heat-affected zone typically signifies careful heat management, which is desirable in welds to avoid weakening the surrounding material.
