Fabricating as an industrial term refers to building metal structures by cutting, bending, and assembling. These processes can cause breakdowns in the materials used and, in some cases, defects or failures in the finished product. Welding is one of the most common processes used in assembling and is usually the focal point of non-destructive testing (NDT).
Welders and fabricators are commonly tested and certified to meet specific welding requirements. Typically, fabrications with welds requiring certified welding also include a non-destructive testing inspection. These inspections can play a vital role in defect detection and initial failure prevention as well as future preventive maintenance.
Common inspections would include radiograph (X-ray), magnetic particle, liquid penetrant, visual, and ultrasonic.
Fabrication / weld inspections are very common at American Testing Services. Our experience with inspections in this field is not only vast in the method of inspection, but also in the methods of welding.
