4. Conclusion
• Homogenous microstructure can be attained by controlling parameters in the additive manufacturing using GMAW. • Impact toughness of the resulting structure is better than the low carbon steel structures with comparable hardness. • Impact toughness in direction parallel and perpendicular to the deposition direction has no significant difference. • The resulting material has a ductile behavior and is lesser prone to catastrophic failure on impact.
