burn to the skin produced by brief exposure to intense radiant heat and
ultraviolet light - ✔✔Arc burn
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 - ✔✔Bonded
an alloy of iron combining iron and usually less than 1 percent carbon to
provide hardness - ✔✔Carbon steel
the flow of an electrical current across an air gap or gaseous space -
✔✔Electric arc
connected to Earth or to some conducting body that serves in place of the
earth - ✔✔Electrically grounded
the point from which a welding arc is produced - ✔✔Electrode

, a material used to dissolve or prevent the formation of oxides and other
undesirable substances on a weld joint - ✔✔Flux
the fumes, gases, and particles from the consumables, base metal, and
base metal coating during the welding process - ✔✔Fume plume
carbon steel dipped in zinc to inhibit corrosion - ✔✔Galvanized
as defined by OSHA, this term refers to an atmosphere that poses an
immediate threat to life, would cause irreversible adverse health effects, or
would impair an individual's ability to escape from a dangerous atmosphere
- ✔✔Immediate Danger to Life and Health (IDLH)
an inert gas, such as nitrogen, used to drive oxygen away from a weld site -
✔✔Purge gas
a gas such as argon, helium, or carbon dioxide used to protect the welding
electrode wire from contamination in GMAW and FCAW welding -
✔✔Shielding gas
an iron-based alloy usually containing at least 11 percent chromium -
✔✔Stainless steel
invisible rays capable of causing burns. UV rays from the sun are the
causes of sunburn - ✔✔Ultraviolet (UV) radiation
