TL;DR: In this article, the residual stress in a large-diameter multi-pass butt-welded pipe joint was calculated for various welding pass sequences by thermal elastic-plastic analysis using the finite element method.
Abstract: Residual stress in a large-diameter multi-pass butt-welded pipe joint was calculated for various welding pass sequences by thermal elastic-plastic analysis using the finite element method. The pipe joint used had an X-shaped groove, and the sequences of welding passes were changed. The distribution of residual stress depends on the welding pass sequences. The mechanism that produces residual stress in the welded pipe joint was studied in detail by using a simple prediction model. An optimum welding sequence for preventing stress-corrosion cracking was determined from the residual stress distribution.

TL;DR: In this article, the effect of dissolved hydrogen (DH) levels on the Ni/NiO phase transition was investigated by employing electrochemical and exposure experiments, and the results showed that increasing DH in water decreased the thickness and the ionic defect transport resistance of the oxide film, in conjunction with the increase of Cr- but decrease of Ni-concentrations in the oxide.

TL;DR: In this paper, the effects of electrode potential and sulphate content in the water on the stress corrosion cracking (SCC) of a low alloy steel transition weld, A508-309L/308L, in PWR primary side waters at 292°C have been studied using slow strain rate testing (SSRT).

TL;DR: In this paper, the transgranular stress corrosion cracking was studied for single crystals of α-brass, copper, and 304L austenitic stainless steel, and it was concluded that the stress corrosion cracks in all systems tested occurred by cleavage.
