Red Seal Welding Practice Exam

For welding, cracking is considered as:

1. The least concern

2. One of the minor defects

3. The most serious defect

4. An easily fixable defect

The correct answer is: The most serious defect

Cracking is considered the most serious defect in welding because it can compromise the structural integrity of the welded material. It can lead to failure or breakage, which can have serious consequences. Options A and D are incorrect because cracking is a major concern in welding and is not easily fixable. Option B is incorrect because cracking is not a minor defect, and requires immediate attention and rework to avoid further damage.
