Description

Most publications on lamellar tearing relate to metallurgical investigations, although some process work has been carried out. At present the designer has to examine the available literature and draw his own conclusions. This report tries to isolate those variables which are important to the welding designer and to explain their relevance in a given situation. It is difficult to adopt a design philosophy for lamellar tearing, when the effect of certain variables cannot be assessed for theoretical and experimental reasons, but the designer must have some evidence as a basis for his decisions. In the final part of the report designs prone to lamellar tearing are examined and suggestions made for modifying them to minimize the risk. Emphasis is placed on anticipation of lamellar tearing, as the cure can be extremely time consuming and costly. There are considerable gaps in the available information on material behavior and recommendations are made for appropriate research.
