Answer :
Final answer:
Moving the electrode too fast during arc welding results in a shallower weld because it leads to insufficient heat application, making it difficult for a proper weld pool to form and solidify.
Explanation:
When arc welding, the speed at which the electrode is moved plays a crucial role in determining the characteristics of the weld. Moving the electrode too quickly can lead to insufficient heat being applied to the metal, resulting in inadequate fusion between the weld metal and the base metal. This scenario typically results in a shallower weld. Therefore, the correct answer to the question is c) the weld will be shallower.
For a quality weld, it's important to maintain an appropriate speed that allows the weld pool to properly form and solidify, thereby ensuring good penetration and bond strength. Moving the electrode too fast prevents this, making the weld not just shallower but also potentially weaker due to poor fusion and possibly more prone to defects such as porosity or lack of fusion.
