From constructing buildings to manufacturing ships, welding is the structural backbone to numerous industries. With over one hundred welding techniques, primarily driven by the base metals, filler rods, electrodes, and environmental factors, welding is a major process used in industry, commerce, and service sectors. The focus of this research is to understand the fumes generated by the Tungsten Inert-Gas (TIG) welding on Aluminum-Lithium Alloy (Al-Li Alloy), estimate applicable emission factors, and identify the heavy metal concentrations of lead, manganese, and chromium. Although there are numerous metals and various welding procedures this study will focus on three main factors: 1. Base metals comprised of Aluminum Lithium Alloy 2195 and 2219 an agehardened copper containing aluminum alloy 2. Weld wire 4043 comprised of aluminum silicone and 2319 comprised of copper silicone 3. Weld techniques of Variable Polarity Plasma Arc (VVPA) and Tungsten inertgas (TIG).
