Additive Manufacturing of Metal Parts by Welding

Abstract

New technologies can be justified with the advent of the additive manufacturing, excels by its flexibility in manufacturing parts of various geometries, good accuracy and material waste reduction savings. This circumstance requires the application of techniques to determine the reliability of the results in the deposition of layers in order to have a good accuracy. This work aims to present a new technology applied to additive manufacturing, focusing on accuracy in the deposition of layers, lower cost and user friendliness man-machine. New method was proposed in order to obtain advantages regarding the use of Plasma welding process. An apparatus for generating plasma was used to obtain the arc. Devices to control speed and position were used to determine essential variables in the deposition of layers’ process. Correlated magnitudes helped in determining Efficient Model of Deposition for use in offsetting the geometric and thermal errors. Computer simulations were applied to the new concept of deposition and the efficiency of the presented system was performed, but no experimental results are provided herein.
