“…Não foram detectadas descontinuidades de soldagem do tipo mordeduras, porosidades e/ou trincas em ambas as amostras comparadas. Portanto, na soldagem realizada infere-se realmente um incremento da profundidade na solda A-TIG, como era esperado de acordo com a literatura [1][2][3]. O fluxo utilizado de Cr 2 O 3 mesmo sendo simples permitiu que a zona termicamente afetada atingisse praticamente toda espessura da amostra como observado Figura 4b [9].…”

“…A soldagem A-TIG (Active Flux TIG Welding) foi desenvolvida pela Paton Electric Welding Institute (PWI) na década de 60 e promove um aumento significativo na penetração do cordão de solda a partir da aplicação de um fluxo de ativação (óxidos e haletos), que é uma mistura de material inorgânico suspenso em meio volátil, na superfície do material antes da soldagem [1,2]. Essa técnica permite suprir algumas limitações do processo TIG (Tungsten Inert Gas), como a baixa produtividade devido à taxa de deposição e penetração rasa.…”

“…To carry out the research work on steel plates material was cut into different shapes and sizes of the weld bead as per need by an abrasive cutter with a blade. These samples-specimens was used in various TIG welding was carried out (such as TIG, ATIG, FBTIG and HTRCFB-TIG) research experiments conducted and papers were published in high impacts journals [8][9][10][11][12][13], as shown in Fig. 5 (a) to (d) and Fig.…”

Metals and Metals-alloys play a significant role in the everyday life of researchers and also in industrial applications to develop a new framework product. New development of tool and techniques help researchers to do their work smoothly. Multi-purpose machines mainly help researchers to do framework design and research as per need and it will save both cost and time. In this paper, the main aim is to develop a machine-stand that performs machine operations in a single column (either side of the column). The operations are cutting, grinding, and drilling. The purpose of the machine is to support researchers in their research work, with high precision to drill without any (human error) vibrations and to cut the work-samples without edges loses. The machine is designed for portable purposes, that can be used in laboratory, field, workshop, and workplace, etc. to do operations of cutting and drilling in various places. The same machine is used for multi-operation, instead of using separate fixed flame machines such as cutting, grinding, and drilling machines. The machine operates through power sources with liquid coolant lubricant and the operations performed simultaneously or individually

“…MIG welding process is an efficient welding process used in high quality welding to produce clean and strong welds, but its use has been mainly restricted to the welding of thin layers of materials in the industry due to the small weld penetration gotten when it is used. In order to solve this problem [7][8][9]. Activated-flux MIG welding was introduced as a method of increasing the weld penetration of the MIG welding process and make it possible to use it for thicker materials.…”

A lot of research work has been carried out varying welding parameters and studying its effects but rare work has been done on application of fluxes in MIG welding. Two different FeO based fluxes; Nano-flux and easy-flo flux powder were applied to the joints of 10 pcs each of 50 x 50 mm stainless and mild steel rods, galvanized and mild steel plates using MIG welding process. The samples used were welded under three categories; includes without flux (control), with nano-flux and easy-flow type-flux powder. The weld of the joints were subjected to mechanical test; hardness, tensile and morphological test; SEM and TEM examinations. The weld joints produced using the fluxes were found to have higher average values of hardness and tensile (stress and strain) of 222.73 BHN, 0.03125 and 199.97 BHN, 0.02785 respectively compare to samples without flux having lowest value of 131.36 BHN, 0.01323. The Microstructural analysis results with the use of SEM and TEM were found to have a better ordered grain structure and improved the structure, surface and pattern of the weld than those produced without flux.. The results obtained has revealed the impact of flux in MIG welding for joining steel gave better joint hardness and the structure of the weld.
