TīmeklisLamellar tearing. Lamellar tearing is a type of welding defect that occurs in rolled steel plates that have been welded together due to shrinkage forces perpendicular to the faces of the plates. Since the 1970s, changes in manufacturing practices limiting the amount of sulfur used have greatly reduced the incidence of this problem. government shared services strategy refreshTīmeklis2024. gada 11. maijs · In this study, weldability and cracking susceptibility of SN 490C steel were firstly investigated.
