    • Combined effect of the interlayer temperature with travel speed on features of thin wall WAAM under two cooling approaches
    Authors: Felipe Ribeiro, Teixeira; Fernando Matos, Scotti; Vinicius Lemes, Jorge;  Advisor: -;  Co-Author: - (2023)

    This work presents the evaluation of the interlayer temperature (IT) with travel speed (TS) combined effect for a given wire feed speed (WFS) on operational, geometrical, and metallurgical features of thin walls with the same width deposited by wire arc additive manufacturing (WAAM) with a low alloy steel, using or not active cooling. A preliminary experimental design was carried out to define a range of IT that could prevent the molten pool from running down and, then, be used in the main experimental design. The main tests were planned and performed to find different IT and TS combinations for a given WFS capable of depositing walls with the same target effective wall width. After s...
