in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...

Welding of niobium and tantalum materials is currently conducted in vacuum or inert gas chambers, which limits the size of the equipment to be produced. The objective of this study is to investigate the means to make TIG welding on these materials in atmospheric environment and analyse the effect of heat input on the properties of welds. It was found that it is possible to make TIG welds on the...

Pathogenic microorganisms are able to adhere on equipment surfaces, being possible to contaminate food during processing. Salmonella spp. and Listeria monocytogenes are important pathogens that can be transmitted by food, causing severe foodborne diseases. Most surfaces of food processing industry are made of stainless steel joined by welds. However currently, there are few studies evaluating t...

The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...

the current work was carried out to characterize welding of aisi 310 austenitic stainless steel to inconel 657 nickel-chromium superalloy. the welds were produced using four types of filler materials; the nickel-based corresponding to inconel 82, inconel a, inconel 617 and austenitic stainless steels 310. of the two joints involved, this paper describes the choice of welding consumables for the...

This paper focuses on optimizing process parameters such as tool rotating speed, preheat-treated workpiece temperature, traverse and pin profile for dissimilar friction stir welding (FSW) of brass AA 6063. The hardness the stir-welded joint created is measured a response variable. Taguchi design experiments approach was utilized to finalize experimental strategy, ANOVA employed analyze data. be...
