摘要

Superalloys like Inconel X750 and Inconel 718 are vital in aerospace and turbine industries due to their exceptional strength, corrosion resistance, and high-temperature performance. However, their high hardness and melting points make welding challenging. TIG welding, known for its precision and clean welds, was employed in this study to join these alloys successfully. Using optimized parameters, such as a current of 70 Amps, welding speed of 60 s, and a shielding gas mixture of Argon and Helium, joints achieved a tensile strength of 623.62 MPa, yield strength of 571.85 MPa, and elongation of 12%. The shielding gas mixture enhanced weld penetration and arc stability, demonstrating its effectiveness in improving joint quality. This study establishes a cost-effective TIG welding approach for fabricating corrosion-resistant, high-strength joints in demanding applications.
