“…They also found that in copper-rich zones, severe intergranular corrosion occurred. Xu et al (2021) also found similar severity of corrosion in the copper-rich zone for TIG welded copper-steel joint in CuSO4 and H2SO4 solution. They observed that in the welded structure, corrosion resistance was higher in steel and lowest in copper, whereas the welded zone yielded intermediate corrosion resistance.…”

“…The solid-state model can provide insights into how waxes interact with other components of crude, such as asphaltenes, which can influence deposition behavior. 38,39 With fusion property estimation, the model may offer a more nuanced prediction, helping industry players make more informed decisions. If successful, such a model could be applied across various crude oils, increasing its utility for the industry.…”

Precipitation of deposited wax on pipe walls is one of the complex flow assurance problems that cause a decrease and complete blockage of oil production rates by reducing the cross‐sectional area of the flow in the pipelines. In addition, surface facilities require higher energy consumption and equipment failure due to paraffin plugs. The purpose of the research is to use the assessment of melting properties in the model of multisolid (MS) forecasting of paraffin in Kazakhstani oil. This article presents the calculation and modification of the fusion properties for a certain Kazakhstani oil for the subsequent calculation of the MS model for predicting wax deposition; numerous approaches have been developed to predict and prevent the flow assurance problems in both science and industry. Most of them are based on predicting the temperature of crystallization of paraffin considering the temperature dependence of the solubility parameters of individual components in the liquid and solid phases, as well as the molar volumes of individual components. Wax deposition can occur anywhere from a reservoir to surface facilities and pipelines. One of the main limitations of the existing models is their applicability to a wide range of crude oil types, while this modified paraffin predicting model will target Kazakhstani crude oil.

“…Micro-structure and corrosion behavior of copper and 316L stainless steel welded joints on an electrolytic copper cathode plate was investigated. Clear phase separation was noted in the weld metal with the γ-and ε-Cu phase dominating the Fe-rich and Cu-rich zones, respectively [30]. A dissimilar joint of aluminium alloy and commercially used copper alloy by friction stir spot welding (FSSW) process shows that the optimized result of welding parameters can be obtained by the weighted aggregated sum product assessment coupled with grey wolf optimization method and pin length is the most significant factor [31].…”

Gas tungsten arc welding (GTAW) is very popular globally as it is capable of doing similar and dissimilar material welding. Most commonly steel and aluminium of different grades are joined using this process. In this research work, two unalike grades of stainless steel i.e., 304 and 316 were welded together with different combination of parameters. An attempt was made to find out the effect on the surface hardness of the joint. The parameters under consideration were current, welding speed and torch angle, having two limits, maximum limit (+1) and lower limit (-1). A mathematical model was developed between input parameters and the responses such as hardness was analyzed by using the factorial approach. The result of the analysis shows that increase in current and welding speed decreases the hardness whereas an increase in torch angle increases the surface hardness. Hardness is maximum at the weld zone of two dissimilar metals and minimum at the heat affected zone.
