X-ray inspection of welded joints

One of the main parameters of any product is its quality – a set of properties that provide the ability to meet needs in accordance with the purpose. An important sign of quality is the durability and safety of operation of this object.

To maintain the quality of the product at a high level, it is recommended to check the object on a regular basis, regardless of the duration and frequency of operation. One of the ways to carry out this check is x-ray control.

The main objects of X-ray inspection are castings and welded joints. 

X-ray inspection of welds

By means of X-ray inspection, it is possible to detect such defects in welds as pores, shells, weld cracks, lack of penetration, non-metallic inclusions in the metal.

How is the object checked? X-ray radiation is directed to the weld, and a special paper is placed on the reverse side. In the process of transillumination, the results of the check are reflected on this paper. The throughput of welded defects is much lower than that of a homogeneous metal. That is why on paper all defects appear as light spots. Based on the outlines and size of these spots, the specialist draws conclusions about the size, shape and location of seam defects.

X-ray inspection requires specialized equipment, as well as a certain set of knowledge and skills in its production. That is why we recommend that you immediately entrust this check to professionals – specialists of our Non-Destructive Testing Laboratory.
