Welding Safety Trade Terms- M1 exam fully solved

Arc Burn Burn to the skin produced by brief exposure to intense radiant heat and ultraviolet light Bonded The permanent joining of metallic parts to form an electrically conductive path that will assure electrical continuity and the capacity to safely conduct any current likely to be imposed on it. Carbon Steel An alloy of iron combining iron and usually less than 1 percent carbon to provide hardness. Electric Arc The flow of an electrical current across an air gap or gaseous space. Electrically grounded Connected to Earth or to some conducting body that serves in place of the Earth Electrode The point from which a welding arc is produced. Flash burn Burns to the eyes sometimes called welder's flash; caused by exposure to intense radiant heat and ultraviolet light. Flux A material used to dissolve or prevent the formation of oxides and other undesirable substances on a weld joint. Fume Plume The fumes, gases, and particles from the consumables, base metal, and base metal coating during the welding process. Galvanized Steel Carbon Steel dipped in zinc to inhibit corrosion. Immediate danger to life and health As defined by OSHA, this term refers to an atmosphere that poses an immediate threat to life, would cause irreversible damage, or would impair an individual's ability to escape from a dangerous atmosphere. Purge Gas An inert gas, such as nitrogen, used to drive oxygen away from a weld site. Shielding gas A gas such as argon, helium, or carbon dioxide used to protect the welding electrode wire from contamination in GMAW and FCAW welding. Stainless Steel An iron-based alloy usually containing at least 11 percent chromium Ultraviolet Radiation Invisible rays capable of causing burns. UV rays from the sun are the causes of sunburn.
