Question

Quizplus · Accepted Answer

Cracking of dissimilar weld metals occurs on the ferritic side of a weld between an austenitic and a ferritic material operating at high temperatures. This is known as weld metal hot cracking or solidification cracking, and can occur due to differences in thermal expansion coefficients and solidification rates between the two materials.
