CTOD designation for WM and HAZ in butt joint made from S460 ML steel, Expertise No. WOiO/II/82/2015

Abstrakt

Typical (normative) testing of materials and/or welded joints do not answer on all questions about material or welded joint properties. In ship building and off-shore sectors, many strucures requires materials and joint with higher than typical fatigue resistance. Imact tests, which are carried out during welding technology qualification, gives answer about ductility, CTOD tests results about material or welded joint ability to dumpping of fatigue crack propagation. CTOD tests have been carried out on order of Mostostal Pomorze S.A.".. The expertise contains: methodology of CTOD tests in accordance with NORSOK M101, BS 7448 Part 1&2, PN-EN ISO 15653:2010; details about fatigue pre-crack procedure, measurement system (with gauge made by GUT) details; results for Heat Affected Zone of butt weld (parent material: steel, grade S460 ML, thicness of 100 mm, welding methods: 136/138); and conclusions
