“…This can include tasks performed on certain equipment through service contracts, cleaning activities, inspections, lubrication tasks, testing, etc. Inspection plays a major role in preventive maintenance as it leads to early detection and correction of faults [11]. It is the most popular maintenance management strategy for production operations [12].…”

Evaluation of Effective Maintenance and Reliability Operation Management – A Review

Manufacturing operations are often carried out with one major goal in mind: to develop products that satisfy increasing customer demand for reliable and high-quality goods. Achieving this target is often hindered by factors such as machine downtime caused by faults in the machinery or production process which leads to time and financial losses. Hence, it is important for operation managers to ensure measures are employed at every stage of production to effectively address these factors and enable unhindered production. Some commonly used strategies include timely maintenance of machines and facilities and reliability analysis of components and processes. This paper assesses the influence of effective maintenance and reliability practices for operations management.

“…In the 19 th century, improvements to the process of welding started in earnest with discovery of the "short pulse" electric arc and the continuous electric arc by Sir Humphry Davy and Vasily Petrov, this resulted in the invention of the first electric arc welding process using carbon electrodes in 1880 by Nikolai Benardos and Stanislaw Olszewski [4]. Further improvements that occurred were invention of metal electrodes in 1888 by Slavyanov and Coffin, the development in Britain of a metal electrode covered with suitable coating by A. P. Strohmenger in 1900 which gave a stable arc as an addition [5]. In 1905, the use of a three-phase electric arc was suggested by Vladimir Mitkevich.…”

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.

In this study, various techniques used in the modification of the grain structure of steel were considered. It was found that different heat treatment techniques cause changes in the grain structure of steel and subsequent improvement in the mechanical properties of the material. More so, the bimodal grain size, as well as the lamellar structure in steel, will lead to work hardening effect and improved ductility of the steel. The carburization technique also improves the mechanical properties such as hardenability, compressibility, tensile strength, and toughness. While nitriding effects will lead to excellent tribocorrosion performance. More importantly, these heat treatment techniques help to improve the resistance against cyclic load in different application environments. Thus, failures resulting from crack propagation and other failure modes are prevented. In this regard, structural failures are prevented by grain structure modification using heat techniques.
