Welding is a fabrication process to agglutinate metals or thermoplastics using coalescence. The process is economical and it is an efficient method to fuse metal permanently. It finds application in a number of industries such as automotive, transportation, energy, construction, shipbuilding, mining equipment and heavy machinery, and aerospace and defense. The items used in this process are known as welding consumables, and can be broadly categorized as filler metals and flux. The metals that melt with the joining materials, and are consumed in the process are called filler metals. Flux is used to produce a gas shield around the weld pool that prevents oxidation of the hot metal.
