What is it about?

The work explores how using ultrasonic arc welding can help reduce radiation damage and radiation-based hardening in welds of CLAM steel. The results show that the ultrasonic-arc welding process is an effective method to refine the weld grain structure of such joints, and the mechanism behind the effects is explained.
