Manual, shielded metal-arc welds on ASTM A 36 structural steel were monitored with acoustic emission equipment. The listening device detected operator inconsistencies and improper electrode deposition during the welding operation. On completion of the weld, acoustic emission monitoring detected slag inclusions, cracking, and martensite formation.
