PENGARUH VARIASI GAS PELINDUNG PADA TIG BRAZING ANTARA CEMENTED CARBIDE DAN BAJA KARBON TERHADAP KEKUATAN GESER DAN STRUKTUR MIKRO

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 adhesive or filler has melting point below to be combined connected. The main objective this study was determine shear strength microstructure weld area joined by brazing method. From results test, there comparison difference stress strength. obtained indicate where test at flow rate 5 liters/minute protective gas gets highest value 108 N/mm2, compared 10 liters/minute, equal 97 but 15 lowest 76 N/mm2. result got due decrease amount Si elements, resulting value.
