The inspection of welds can be carried out using various nondestructive methods. There are a number of defects that occur uniquely in weldments that trained welding inspectors are able to identify. Defects such as porosity and problems in the heat affected zone (HAZ) can be identified using visual means. Measurements can be taken of the weld dimensions to ensure compliance to design specifications.
Welding inspection is carried out both directly after manufacturing and in periodic in-service inspection. LTC inspection engineers are fully qualified to inspect welded structures and other fabrications. and have significant experience in identifying weld defects. Many amusement devices are welded in structurally critical areas, and so it is vital to use trained welding inspectors to ensure a thorough, competent examination.
