Wire Arc Additive Manufacturing for Industrial Part Fabrication: A Short Review

Abstract

The purpose of this review is to summarize the status of wire arc additive manufacturing (WAAM) in industrial parts and identify future research topics. First, a literature review of the results of studies on WAAM for industrial parts was conducted to summarize the current literature. Based on the study results obtained through the literature review, the main current issues are summarized. It was found that studies on WAAM have been conducted for a variety of industries, but not for all industries where arc welding, the basis of WAAM, is used. In addition, many studies have been conducted on steel, whereas no studies have been conducted on titanium or multi-materials. The study concluded that an effective means of expanding the industrial use of WAAM is to treat the uncovered topics.
