Metal welding processes, and electric arc in particular, constitute a key link production chain comprising large number of companies. This fact, addition to growing trend favour more in-depth environmental analysis control industry, the need continue affording due consideration economic aspect set stage for this study. Herein, an is conducted four types welding: TIG with without filler, MIG, MA...

In this research, the effect of shielded metal arc welding (SMAW) process heat input upon microstructure and development heat-affected zone in dissimilar joint API 5L X80/DS5 2205 steels was investigated by recording thermal cycles with thermocouple implantation perpendicular direction weld line. The filler used (electrode) is DSS 2209. base metals their interfaces at different inputs were usin...

Austempered ductile iron (ADI) is a new engineering material type which continue receiving increased attention in research and industry. Extensive conducted so far has demonstrated that ADI excellent property combination such as high strength-weight ratio, ductility toughness, good fatigue strength, damping properties wear resistance. As result of to their exceptional mechanical mix, fabricatio...

Abstract During the process of regeneration machine parts, certain phenomena occur that have a significant impact on loss their working ability. Hereditary properties are expressed by interdependence geometric and physical-mechanical-metallurgical parameters gear teeth created during technological operations worn hard-facing. The influence type additional material (electrodes combinations) trib...

In the present work, structure health monitoring (SHM) of welded steel pipes was used to diagnosis their state via vibration based damage detection techniques. The dynamic quantities such as Frequency Response Functions (FRFs), mode shapes and modal parameters from structural vibration to detect damage were measured, set on linear averaging mode, with a maximum frequency of analysis of 3.2 kHz....

Roll Bar merupakan sebuah peranti keselamatan pada mobil balap yang wajib untuk melindungi seorang pembalap meminimalisir resiko disaat terjadi kecelakaan. juga memiliki fungsi dalam kabin agar kecelakaan tidak langsung mengalami kerusakan fatal. Penelitian ini tujuan mengetahui hasil perbandingan kekuatan sambungan las TIG maupun SMAW terhadap material pipa Seamless Sch 40 sebagai bahan baku p...
