Abstract

The present work aims to analyze the mechanical behaviour of laser-welded Inconel 825 and AISI 410 welded joints. The main goal of this study is to assess the Vickers microhardness, tensile properties, and metallurgical features (using SEM and EDAX) of welded joints under different operating conditions. In Laser Surface Modification, laser welding was performed at 1200 W to 1800 W, with a welding speed of 30 mm s^-1 and a laser head focal distance of 200 mm. The gap between the materials during welding was 0.05-0.2 mm. The mechanical properties of the welds were assessed using Vickers microhardness testing and tensile testing. The microstructural examination and element analysis of the welded joints were performed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The mechanical and microstructural integrity of the joints as a function of laser power, welding speed, and gap distance is discussed. It provides an important reference for optimizing laser welding technology for similar-metal welds in high-strength, high-temperature dissimilar-metal joints.
