Abstract
This work involves with investigations on Maraging steel weldments done by GTA welding technique. Similar welding of maraging steel plates of 5mm thick using ErNiCrMo-3 filler wire was done in order to evaluate the weldability and performance characteristics. Micro structural and X- Ray diffraction analysis were done to analyze the structure and phases developed post - weld. Block martensite was formed in the heat affected zones of the parent metal. Tension testing using different strain rates and hardness profile measurements were done to investigate the mechanical properties and the study concludes that the strain rate has considerable influence on the nature of ductility whereas it has very less influence on the Ultimate Strength of Maraging steel. © 2013 The Authors.
