摘要
Abstract
In this paper, the properties of transverse cracks formed during the welding in the jacket of offshore platform were analyzed. By layered grinding and dye-penetrant test method, the cracks were detected in the HAZ near the base metal. The size of these cracks was less than 0.5 mm generally. The crack shape and inclusion elements were tested, the result showed that a large number of multiple inclusions with complex composition and low-melting-point eutectic exist in the cracks. These cracks are broad; the inner surface of the crack is smooth and show the typical intergranular fracture mode. All the properties indicated that these transverse cracks are HAZ liquation cracks.关键词
