Fig. 19 Methods used to reduce lamellar tearing. (a) Angling the weld fusion line to avoid shrinkage stresses in the through-thickness direction. (b) Use of smaller partial-penetration welds to reduce joint restraint. (c) Placement of welding beads on the thinner plate (when welding plates More

Fig. 6 Typical location for lamellar tearing in a T-joint. Stress across the plate thickness (the z- direction) occurs from strains that develop from weldmetal shrinkage in the joint. Lamellar separation is roughly parallel to the fusion line. Lamellar tearing can be prevented when More

... of tests for determining the susceptibility of the weld joint to different types of cracking during fabrication, including restraint tests, externally loaded tests, underbead cracking tests, and lamellar tearing tests. Weldability tests are conducted to provide information on the service and performance...
