Non-destructive butt weld inspection method |
摘要 |
A non-destructive plastic butt weld inspection method in which the weld bead 42 is removed from an exterior surface of a weld zone region 44 of a butt weld and the weld zone region 44 is heated to a temperature sufficient to visualize the weld zone 44. After heating, defective joints are readily identified by the appearance of a bond line 40 in the weld zone 44 while satisfactory joints merely show the weld zone 44 with no evidence of a bond line 40. Surface irregularities such as ridges 46 and indentations 48 may also form in the weld zone during the heating step.
