For the design of welds, see Lectures 11.2. Welding is the process of joining materials - usually metals or thermoplastics - by causing fusion, a method of metal-joining technique that involves melting the base metal. As electricity passes through the electrode, the flux forms a gas, which shields the electric arc in the space between the electrode and the metal being welded, preventing . In a welding symbol, the root opening measurement is located inside the weld symbol. Alternatively, the final attachment can be made by welding, as long as the final attachment criteria in §1926.757(b) for welded final connections are met.
