Welding is the most common method of joining materials. As we push material performance to cope with more difficult operating conditions, welding requirements also become more demanding. DNV helps you ensure that the welded constructions perform as intended.

Purpose

Welding is used to join materials to ensure a solid connection, while NDT is applied to verify that the welded joint has acceptable integrity without any detrimental defects.

Benefits

A welded joint with adequate integrity to withstand the loading and environmental conditions for the weld’s design life is obtained by using a correct design and selection of welding method, filler materials and welding parameters for the actual weld configuration and by using the most appropriate NDT methods for inspection.

DNV’s testing facilities and competence will give the client the possibility to check that the quality of their respective welded connections will meet the requirements specified in recognised international standards or any additional requirements due to specific operating conditions.
