There are hundreds of weldability tests that have been developed over the past 50 years. These tests attempt to quantify some aspect of material weldability or, as a minimum, give some indication of material performance during fabrication and/or service. Many of these tests focus on cracking that occurs during welding and often apply external loads in bending or tension to produce cracking in laboratory samples. This presentation will summarize the current state-of-the-art with respect to weldability testing and review some recent developments in test methods and procedures that show promise for providing reliable quantification of material weldability.
