ANALISIS METALOGRAFI SAMBUNGAN LAS DENGAN SCANNING ELECTRON MICROSCOPE (SEM) DAN TENSILE TEST MENGGUNAKAN BAHAN PADUAN SUPER DENGAN METODE TIG BERBASIS NIKEL

Abstract

The objective from this research is to find (1) plane blade turbin condition in microstructure based super alloy with nikel in normal condition; (2) tensile strengh of the plane blade turbin from result repair in maksimum using method Tungsten Inert Gas (TIG) welding is criteria to apply and fulfill a condition as repair method damage. The experiment is used in this research. A super alloy nikel (Ni) as population in this research and purposive sampling is used to taking sample technique, normal condition in a super alloy nikel (Ni), TIG welding result with variation flux steam welding. Descriptive comparative methods analysis is used to data analysis. The research result show that : (1) surface microstructure observation have characteristic strong and stern appearance on super alloy material in normal condition; (2)  flux stream variation and same material TIG welding from super alloy with materials nickel use a artificially filler in experience welding process have different of elongisitas and maksimum tensile strength; (3) the best material to use flux steam 70 A is material super alloy with nickel use filler rod was finding in this research.
