Selecting a process for welding large scale equipment on site demands special expertise due to the numerous variables be considered. This paper is aims applying decision support methodology selection of 16000 cubic meter storage tank welded site. Five processes are chosen select from, namely, Gas Metal Arc Welding (GMAW), Shielded (SMAW), Submerged (SAW), Flux Cord (FCAW) and Tungsten (GTAW). T...

Salah satu jenis stainless steel yang cukup kuat, tahan terhadap korosi, mampu mencegah kontaminasi dan mudah dibersihkan adalah AISI 304 . Dalam aplikasinya di dunia industri penyambungan material ini sering menggunakan pengelasan, dengan parameter pengelasan berbeda-beda, sehingga akan berpengaruh sifat mekanis tersebut. Pada penelitian pengaruh dari arus mekanik pada gas metal arc welding (G...

Euro-6 norms for reduction of CO2 emissions and ECE-R66-01 regulation safer passenger transportation became legislative obligations bus builders. These two adaptations increase the weight a as nearly 600kg which also increases fuel consumption 1.5-3%. Dual phase (DP) steels can compensate these by decreasing thickness components. Because, ferrite provides steel with good formability martensite ...
