Laser Metal Deposition of Inconel 625 Alloy – Comparison of Powder and Filler Wire Methods

Abstract

Abstract. This article presents comparison of laser metal deposition methods. The main methods presented in this work assume use additional materials in a form of metal powder and filler wire. An important differences and problem with deposition of two different additional materials was presented. A comparison of abovementioned metal deposition methods of Inconel 625 alloy was shown. Microstructure analysis performed on manufactured specimens was presented. Differences in deposition mechanism for both methods were shown.
