Advanced welding technologies used in aerospace industry

The purpose of the research is comparison of welding processes for the aerospace industry and identification of optimal welding technologies used in the recent decades. The research was conducted by a critical review of literature, published and e-papers on the value of modern advanced welding technologies for aerospace industry, including their fundamentals and application for aerospace structural components. This work is mostly an articles-based study that includes the articles in the area of welding investigations in aerospace industries. The articles were identified through multiple formal search methods including electronic searching of main databases (ScienceDirect, Springer and Elsevier), the use of free-texts, index terms, named authors, reference scanning and citation tracking. Based on the findings and subsequent discussions, it is found that conventional fusion welding technique is no longer competitive to fulfill the demanding standards of aerospace industry, therefore advanced welding technology is the main choice of large global aerospace companies as reliable, sustainable and efficient joining processes, which bring prospects for further development of new light weight aerospace materials and structures. The information provided in this work can be used as the comprehensive review of current trends in joining of aerospace structures with advanced welding processes and as the basis for further scientific research on the industrial implementation of advanced welding in the aerospace sector
