What might cause excessive spatter during SMAW?

Excessive spatter during Shielded Metal Arc Welding (SMAW) can often result from using too high of a current setting or an improper electrode angle. When the current is set too high, the increased heat can lead to a more vigorous welding arc, which can cause molten metal to be expelled from the weld pool, resulting in spatter. Additionally, if the electrode angle is not oriented correctly, it can disrupt the arc stability and control over the weld puddle, further contributing to spatter.

Proper management of both current settings and electrode positioning is crucial for achieving a clean and controlled weld. By maintaining the appropriate current levels and ensuring the electrode is held at the proper angle, welders can minimize the occurrence of spatter, allowing for a smoother and more aesthetically pleasing weld.
