Using the wrong electrode extension for a specific electrode can result in very poor welding with slag inclusions, porosity, and a lack of ____.
A) homogeneity
B) consistency
C) fusion
D) uniformity

Question

Quizplus · Accepted Answer

Using the wrong electrode extension can result in a lack of fusion, which is the joining of two materials into one continuous piece. The correct electrode extension is critical for maintaining a proper arc length and ensuring the proper amount of heat is applied to achieve fusion. Without fusion, the weld joint will be weak and prone to failure. Slag inclusions and porosity can also be a result of improper electrode extension, but the lack of fusion is the most significant issue.
