During the supervision of making steel constructions we review the quality of welded joints, the quality of embedded basic and additional materials, quality of performed corrosion protection, appropriateness and validity of certificates of welders and welding procedures, particularly in the area of compliance of performed works with the project. While monitoring constructing of gas pipelines per customer request, we can assume exclusively monitoring of execution of welding works, while inspecting a welding contractors documentation, quality of added materials, visual, ultrasonic or radiographic review of welded joints, control of execution of the prescribed welding technology.

When monitoring the examinations of HDPE on the aforementioned types of objects we review all welded joints visually, ultrasound method and as wells as mechanical testing of samples. We also provide a follow-up of necessary welding documentation.
