Welding Defects Meaning

Where defects of this type are likely to occur other NDE techniques such as ultrasonic testing are preferable to radiography. Incorrect procedure or poor technique may produce imperfections leading to premature failure in service.

The welds and other fasteners failed to sustain the weight of people crowding onto the walk during a tea dance.

Welding defects meaning. Incomplete root fusion or penetration. TWI CSWIP 31 32. After complete welding identification number is punched near joint.

Welding procedure joint features and access and welder technique will have a direct effect on fabrication imperfections. Welding defects are the irregularities that are formed due to the wrong welding process or due to inexperienced welders. Lack of side wall fusion.

Welding defects can be defined as weld surface irregularities discontinuities imperfections or inconsistencies that occur in welded parts. 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. This lack of sensitivity to planar defects makes radiography an unsuitable technique where a fitness-for-purpose approach is taken when assessing the acceptability of a weld.

The defect may differ from the desired weld bead shape size and intended quality. An ideal weld or good weld should be such that adequate fusion exists between the filler metal and edge preparation together with good penetration. A single crack is considered a weld defect.

Welding defects are generated in a welding job due to the faulty or poor technique used by the inexperienced or unskilled welder or due to fundamental difficulties in the welding operation. Following defects or discontinuity can be revealed by visual inspection. Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns etc.

Code specs for welding address the finished shape dimensions and extent of any anomalies in the finished weld. Complete visual inspection is done and any surface breaking or defect shall be repaired as per approved procedure.
