“…These powders include epoxy, nylon, polyester and urethane. However, poly coating is mostly used for metal sheets [15]. Thus, protective coating involves the spraying of metals with paints using the conventional method as shown in Figure 1 below.…”

It is natural to define marine corrosion in terms of the different zones in which the corrosion occurs such as atmosphere splash, tidal and sea mud etc. However, this study focused on issues affecting the marine structures, different types of corrosion and their impact on the marine steel structures as well as the machinery/equipment. Furthermore, several control measures of corrosion necessary to avert corrosion in marine environments were discussed. However, it was established that prolonged contact of marine structures with seawater would lead to corrosion as well as ruing the safety elements present. Thus, the study provides potential information to material scientists on the need for using structural steels of adequate mechanical properties.

“…Figure 4 showed the various properties of the aluminium alloy during the welding process. A study by Lu et al [15] reported that aluminium 7055 alloy developed from spray forming technology can have up to about 600 Mpa after undergoing deformation and heat treatment. In addition, the aluminium alloy is associated with properties such as ease of machinability and adequate toughness.…”

“…To this end, Lu et al ( 2022) investigated the heat-affected zones of some samples subjected to single and secondary thermal cycle and this was simulated via heat treatment method. The study focused on the effect of the secondary thermal cycle softening action and the dynamics of HAZ during the TIG welded spray formed 7055 aluminium alloy [15].…”

The review focused on the applications of tungsten inert gas a (TIG) metal inert gas (MIG) welding processes. Each of the welding process was critical studied to understand the operations and the need to maintain safety and reliable weld with adequate mechanical properties. In addition, the various applications in the aerospace, aeronautic, automotive and food packaging industries were critically highlighted. However, there potentials as well as problems highlighted have been critically reviewed and reported especially porosity which usually result into hole defects at the weld joint as well as plastic deformation due to the frictional heat induced have been reported in this study. Furthermore, the study further recommended friction stir processes integrated with TIG/MIG welding as an alternative method that will solve the problems associated with fatigue behaviour of welded joint. Thus, the study provided potential information to all stakeholders especially the professional welders on the need-to-know which method is applicable to aluminium alloy welding

“…Conventional fusion welding techniques, such as gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), and plasma arc welding (PAW), are widely used in joining aluminum alloys due to their versatility and ease of implementation. However, one significant drawback associated with these techniques is the formation of a large HAZ, owing to the high heat inputs, thermal conductivity, low melting point phases, and thermal expansion mismatch of aluminum alloys [ 13 , 14 ]. Moreover, cracks during solidification, porosity in the weld zone, and liquation cracking are among the specific types of defects commonly observed in the fusion welding process of aluminum alloys.…”
