As a part of component integrity test program at Bhabha Atomic Research Centre, fatigue tests on full scale pipe and pipe welds were conducted in addition to CT and TPB specimens. In this paper the outcome of this program is discussed. Specimen testing was conducted to determine the basic cyclic stress strain curve, LCF and FCGR properties. FCGR tests were conducted on CT and TPB specimens to u...

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...

The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...

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...
