- Abstract:
-
By employing active cooling methods with a steel-depositing wire-arc additive manufacturing (WAAM) system we have shown the hardness and yield strength of prints can be manipulated on-the-fly. The purpose of this research was to determine the scope of influence active cooling can have on the mechanical properties of WAAM printed steel. Active cooling is achieved by applying coolant onto deposited material continuously and directly behind the molten puddle. Tensile specimens are cut from thin walls of stacked single width passes. Tensile and hardness tests show the yield strength of ER70S-6 can increase up to 90 KSI and 10 HRC points respectively.
