Offset or mismatch are terms associated with a condition where two pieces<br />
being welded together are not properly aligned. The radiographic image is a<br />
noticeable difference in density between the two pieces. The difference in<br />
density is caused by the difference in material thickness. The dark, straight<br />
line is caused by failure <strong>of</strong> the weld metal to fuse with the land area.<br />
