Welding uses fusion to permanently bond different metal pieces together and it plays an indispensable role in construction. Metal framing and components can be welded together by a fabricator and also welded together in the field. Welding can connect steel I-beams, trusses, columns and footers, to support the walls, roof and floors of a building. Numerous welding techniques exist: shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and flux core arc welding (FCAW). Welding uses diverse tools: welding clamps, torches, power sources, consumable electrodes and specific safety equipment. To ensure structural building integrity and durability, and prevent structural failure, the welding process must be completed without errors. Welding errors produce defects, flaws or imperfections that compromise the intended use of a weldment. While not a complete list, here are some common welding errors and how to avoid them.
