... ABSTRACT High Frequency-Electric Resistance Welded (HF-ERW) steel pipes are suitable for products with thin wall thickness and high accuracy. However manufacturing high chromium steel is difficult by deterioration of corrosion resistance on weld defects. And so by applying quasi-laminar plasma...

... strength, weld strength, weld toughness, or the presence of unintended weld defects in a specimen designed to contain just man-made defects. Post-test fractography and metallurgical examination are very useful in explaining the performance of a FST; therefore, aspects of failure analysis are discussed...

... engineering structures for the transportation of oil and gas from one place to another. In recent gas pipeline projects, ECA (Engineering Critical Assessment) has often been carried out to decide the acceptance criteria for the weld defects. The ECA is usually conducted according to the acknowledged standards...

... ABSTRACT This paper presents methodology and design criteria for assessment of pipeline girth weld defects that may result in circumferential failure. It covers major failure modes such as plastic collapse, local buckling and fracture for the limit state design. The existing strength equations...

... ABSTRACT The X-ray radiographic testing method is often used for detecting weld defects as a non-destructive testing method (HDT). Due to the difficulties in identifying small defects from the X-ray film, skilled laborers should be trained. However, recently it has been difficult to employ...

... stress, weld defects, etc .. Since there is also a tendency that offshore structures are built in deeper sea areas at lower temperatures, it may be more important to prevent the brittle fracture of welded joint for safety of offshore structures. In order to avoid brittle fracture of a 332 welded joint...
