Welding is one of the key processes in any industry, notably for those that handle metal and metal products. It is through welding that products, both made of steel, are melded through a metal rod that heats up and sparks upon contact with the metal to be welded, and in the process, melting isolated parts, specifically the parts that have to be mended. The parts that are welded in metals include the corners and junctions of various sections. Having said that, this is an important, and indispensable process in construction, whether it be bridges, houses, buildings, so on and so forth.
Welding is a process that involves high energy, and therefore, high heat, regardless of the mechanism being employed, which could range from Shielded Metal Arc, Gas Tungsten, Gas Metal Arc, Flux-cored arc, Electric Resistance, to Submerged Arc, that makes use of different mechanisms to generate heat and allow metals to melt and eventually fuse. These mechanisms are employed for different classes of metals given that different metals exhibit different properties as well.
Importance of Welding Helmets
Given that the welding process involves heat, and in particular mechanisms, radiation, ultraviolet light, sparks, as well as infrared light, it is not a surprise to know that there are several negative health impacts that come with constant exposure to jobs that have anything to do with welding. Having said that, there have been several materials that have also been made to cater to people’s protection during welding jobs to protect from the negative health effects such as inflamed corneas, and burnt retinas, both of which are serious complications that could result to blindness. To help with this, welding helmets are made, and to further improve its efficacy, auto darkening welding helmets have been created as well.
