Lack of side wall fusion. Even if irregularities are very minimal but if the shape size and quality of the weld are way different than what is expected it is also called welding defects. Welding procedure joint features and access and welder technique will have a direct effect on fabrication imperfections.
Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns etc.
Incorrect procedure or poor technique may produce imperfections leading to premature failure in service. Incomplete root fusion or penetration. An ideal weld or good weld should be such that adequate fusion exists between the filler metal and edge preparation together with good penetration. Where defects of this type are likely to occur other NDE techniques such as ultrasonic testing are preferable to radiography.
