Dissimilar metals have found wide use in electric power generation, electronics, reactors, nuclear, petrochemical, chemical industries, civil construction, vessels, and heat exchange as well several other industries. TIG welding (Tungsten Inert Gas Welding) is a type of that uses tungsten the electrode material not consumed. Brazing way joining metal materials through heating process with an ad...

Laser welding-brazing was used to join cemented carbide WC-Co and steel dissimilar materials. In this study, high-speed welding adopted. The effect of parameters brazing filler metals on the macrostructure, elemental diffusion, micro hardness thermomechanical behavior analyzed using optical metallography, scanning electron microscopy, probe micro-analysis, test, finite element method (FEM) base...

Abstract Brazing is a crucial joining technology in industries where nickel-superalloy components must be joined. Nickel-based brazing filler metals are extensively employed, possessing excellent mechanical properties, corrosion resistance, and retained strength at elevated temperatures. To function as metal, the alloy melting point reduced to below that of materials being joined, but addition ...
