Which is a common defect that can occur in welded joints?

• A. Poor fit-up
• B. Cracking
• C. Burn-through
• D. All of the above

Answer: (D)

Welded joints can experience various defects during the welding process, and all the listed issues are indeed common. Poor fit-up occurs when the parts being welded are not aligned or held together properly, which can lead to weak welds or misalignment. Cracking can happen during or after the welding process, often due to thermal stresses or improper material selection, compromising the integrity of the joint. Burn-through refers to when excessive heat causes the base metal to melt through entirely, resulting in holes or gaps in the weld. Recognizing that all these defects are potential issues helps welders understand the importance of proper technique, preparation, and execution in the welding process. Each defect highlights the need for careful planning and execution to ensure strong and reliable welded joints.
