Study on formation of aluminum alloy thin wall produced with WAAM method under various thermal conditions

Abstract

The study reveals some formation aspects of a thin walls made by WAAM technology. The series of experiments about thin wall deposition in a various thermal condition was carried out. Temperature field finite element model was developed and solved under the giving conditions. Experimental results were treated after metallographic analysis, functional dependences of the width and height of the deposited layer by the temperature of the previous layer were constructed. In a range of 30-300 C sublayer temperature, layer height and width values show linear functional dependencies by sublayer temperature.
