If the electrode is moved too quickly when arc welding, what is the consequence?

Moving the electrode too quickly during arc welding leads to insufficient metal being deposited in the weld. This happens because the welder does not spend enough time in one position to allow the molten metal to fill the joint properly. A slower and more controlled movement allows for better penetration and fusion of the base metals, ensuring a strong weld joint.

When the electrode moves rapidly, the heat generated may not be sufficient to melt an adequate amount of filler metal or base metal, leading to a weaker weld. This can result in issues such as lack of fusion, where the weld fails to bond properly to the base material, compromising the overall structural integrity. Therefore, maintaining the correct travel speed is essential to achieving a strong and effective weld.
