Welding is often referred to as “industrial craftsmanship”, a term that is justified given the detailed process involved in combining metals through a complex interaction of electricity, heat, melting, mixing, and solidification. In most cases, welding is done to achieve smooth metal joints that are both reliable and visually appealing. From bridges and airplanes to pipes, medical devices, and beyond, welding remains a ubiquitous technology in achieving remarkable results across various industries. Even though welding is used to join some of the most precisely engineered infrastructures in the world, its techniques and practices remain variable and inconsistent. Even though large-scale welding applications are becoming more and more automated, manual welding still prevails in many applications depending on the expertise and skills of a welder. Either way, the process depends on weld parameters that were validated many years ago.
