Welding of special metal tantalum
Among refractory metal materials, tantalum (Ta) has a high melting point (2996°C), an extremely low ductile-brittle transition temperature (-196°C), good plastic processing and forming properties, excellent corrosion resistance, wear resistance, creep resistance and high-temperature mechanical properties. It is widely used in many high-tech fields such as aerospace, nuclear industry, metallurgy, chemical industry, and national defense.
