A Review of Weldment Failure Modes and Weldability Testing Methods.
Abstract
An engineering study was conducted that reviewed typical weldment failure modes and the types of weldability test procedures currently used to predict behavioral response of a material that is to be welded. In comparing the design effectiveness of these tests, each has certain inherent technical advantage/disadvantages associated with it. The tests, if used appropriately, can save untold time and costs associated with poorly welded structures/ components that fail in service prematurely. They are divided into two major categories, direct and indirect, related to the test methodology or procedure used to generate results. Specifically, direct tests make use of actual weldments, while indirect tests utilize basic metallurgical principles to predict weld behavior. From this study, it should be apparent that determining what the most appropriate weldability test procedure is for obtaining useful results for a given situation is critical to the success of that test.
