VISUAL TESTING

We perform accredited visual testing (VT) in accordance with the following standards:

EN ISO 17635
Non-destructive testing of welds - General rules for metallic materials

EN ISO 17637
Non-destructive testing of welds - Visual testing of fusion-welded joints

EN ISO 5817  
Welding - Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) - Quality levels for imperfections

EN ISO 10042
Welding – Arc-welded joints in aluminium and its alloys – Quality levels for imperfections

DS/EN 1090-2
Execution of steel structures and aluminium structures - Part 2: Technical requirements for steel structures 

NORSOK - M101
Structural steel fabrication

NORSOK M-601
Welding and Inspection of piping

ASME BPVC-V - 2019
Section V-Nondestructive Examination

Eniso has a flexible accreditation and are therefore able to implement other method-specific harmonizing standards in the quality system. All accredited testing is performed by ISO 9712 lvl2 / 3 certified personnel and all inspections are documented with a test report.

A good visual test of the welds is essential and can minimize the need and scope of additional NDT afterwards. This can minimize the cost associated with approval of welds. Many standards allow VT to be performed as an internal control if the executive staff are qualified. Eniso Nordic can train personnel for internal control and provide specific and general procedures for this.
