Abstract
This work of undergraduate research involves the study of the influence of welding pulse energy Nd: YAG laser on the balance of phase ferrite/austenite duplex stainless steel UNS S32205. The laser weld beads are obtained with varying intensity of the laser beam 10-60 W/cm2, maintaining the pulse energy equal to 6.0 Joules, the temporal width of 4, 6, 8, and 10 ms, and depths of focus 1.0,…
