Bahan baja tahan karat (stainless steel) banyak digunakan dalam industri rumah tangga maupun militer, dan juga nuklir. dibagi menjadi lima tipe yaitu austenite, ferite, martensite, duplex precipitation hardening. Baja feritik merupakan alternatif yang menarik produksi kendaraan karena sifat ketahanan terhadap laju korosi. Logam tidak sejenis mempunyai karakteristik berbeda satu dengan la...

Gas tungsten arc welding (GTAW) is considered a well-established process in the manufacturing industry. Despite, certain challenges associated with high hardness of heat affected zone and cold cracking susceptibility joints, are main barriers for this to be implemented successfully within integrity structure. By using combined procedure experiments modelling (response surface methodology (RSM) ...

Abstract Gas tungsten arc welding (GTAW) technology is widely used in industry and has advantages, including high precision, excellent quality, low equipment cost. However, the inclusion of a large number process parameters hinders its application on wider scale. Therefore, there need to implement prediction optimization models that effectively enhance performance GTAW different applications. I...

The article describes problems of welding heterogeneous welds be specific heat resistant steel X15CrNiSi20-25 with cobalt alloy Stellite 6. Heterogeneous are produced by GTAW (141 according to standard EN ISO 4063) method. major goals the experiment were performing preliminary specifications (pWPS) for a welded part. Further was necessary this weldment set parameters on mechanical testing.
