What is a common consequence of using improper electrode angles during welding?

Using improper electrode angles during welding can significantly reduce the weld strength. The electrode angle affects the penetration of the weld into the base material and the overall fusion of the weld metal with the base metal. When the angle is too steep or too flat, it can lead to inadequate fusion, resulting in a weaker bond between the materials being welded. This decreased strength can make the weld more susceptible to failure under load or during service, which is critical in structural applications where integrity is paramount.

In addition to reduced weld strength, improper angles can also create a variety of defects, such as undercuts, excessive spatter, and inconsistent bead appearance, all of which can compromise the overall quality of the weld. Ensuring the correct electrode angle is essential not only for achieving the desired strength but also for maintaining quality and reliability in welds.
