Analysis of weld toe profiles and weld toe cracks

Abstract Measurement of actual weld toe profiles showed that a wide combination of weld toe angles and toe radii are possible. Experimental and finite element analysis of stress concentration and stress distribution was carried out for a particular cruciform welded joint. Closed-form stress pattern equations were compared from different sources. Stress intensity factor calculations using closed-form integration and weight function methods were carried out for weld toe cracks.
